tank session mocked up by Sound Current Meditation

So, I was not in my tank. I was sitting indian style and doing some Sound Current meditation. I got sleepy and laid down. Next thing I knew, I was gasping for air and pushing upwards to the top of my tank. My nose crashed into the ceiling of the tank.Right around this time, I realized that I had not been floating but merely laying down for a nap after a session of Sound Current meditation.

Cool!

[thedeepself] Silva Mind Body Healing

It’s a very powerful audio. I dont know if you know Jose Silva’s background, but it’s a fun read, how he was in a barbershop and wanted to learn Electronics so the barber said he’d pay for the course if he would put his name on the certificate.Then he read about the alpha rhythm and designed a little device to make the pecking sound at the right frequency and his children started demonstrating psychic powers while he was going over their homework with them. 

And the data on healing cancer by mind alone is simply staggering:

Read all about Dr. O’ Carl Simonton, a world-renowned
oncologist and author who uses imagery therapy
to teach patients to heal themselves, even from cancer.

Dr. Simonton has said, “About the Silva system,
I would say it is the most powerful single tool that
I have to offer patients.”

This is a must read for anyone who has a family
member who is at risk or suffering from a “terminal”
disease like cancer.

I think it’s well worth being on their mailing list – they have some interesting data.

Great to play in a floatation tank.

responsibility for players; intra and extra tank fantasy; heating the float room and bathroom

I woke up this morning and did a 30 minute insight meditation. After that, I realized that all trauma has to do with thinking a separate “I” was injured by a separate other. This is called the Responsibility Scale of 1962 in L. Ron Hubbard’s writings.So anyway, I was laying in the tank, doing something. I was either watching my breath or watching thoughts and studying how I felt I was separate from the person I was thinking about.

Before too long, I was having the following fantasy:

 

I was rolling down a river in my float tank and the river fed into a highway. I needed to get off the highway because I was low on air (to breathe). So I parked at a zoo and got out of my tank. Two girls saw me and asked me about my tank. I described it and one of them started telling me all about her former jobs. She got fixated on one job she had with people on welfare. One client had an issue with her taking pictures of him and went ballistic.It was about this time, I decided to stop dreaming and get out of the tank. So I got out and John Lilly was there in a bright blue Hawaiian shirt. I asked him what he thought of Scientology, since I had always wanted to do that. He said: well, they think they know something and are now just trying to figure out how to prove it. I dont work that way.

So I reflected on that advice and I realized that I got out of my tank using shock struts – but that was the old design. So then I realized I had never gotten out of the tank and was still in.

So this time, I really wake up 🙂

One neat thing I did this time was heat both the bathroom and the float room to 80 deg F so that I was not shocked by cold air when leaving the float room. That was a nice touch.

ah, refreshing! near electrocution!

# ah refreshingNothing like a float to clear the mind. The float itself was _horrible_ – I’m struggling to set the perfect temperature for my heaters and match that with room heat. And fight with floor coldness as I did not put down 2-inch thick styrofoam to insulate the tank bottom.

But even with that horrible float (where I noticed coldness at times and I dont have enough salt so my knees poke out and my head drops back too much), I came out refreshed and ready to deal with all the stuff that was aggravating me before I climbed in.

# near electrocution

The other night, I decided to do a tank sleep. 2.5 hours later as I’m getting out, I notice that one of the heaters was not unplugged — I had moved around some things and forgot to put one of the heaters on the GFCI power strip.

I guess that was me balancing my karmic debt with the goldfish 🙂

Pondmaster 1250 problems

Hello, as you can see in these 2 videos: 

My pondmaster is not sucking up any debris in my tank. My tank is 8′ x 5′ x 16″ and has 300 gallons of water with 1000 pounds of epsom salt (specific gravity 1.25 or so — much higher than an aquarium):

https://lh3.googleusercontent.com/_Pu5idg9RIVo/TWwEr8_nTTI/AAAAAAAAA_c/FyE4KCUCxFE/s800/IMAG0057.jpg

This pondmaster was recommended to me by tech support, yet it is not doing any cleaning.

I did have to put rocks in the input tray of the pondmaster to weigh it down:
https://lh5.googleusercontent.com/_Pu5idg9RIVo/TXeUCNYheCI/AAAAAAAABAo/A9sI-JvVDMs/s800/IMAG0075.jpg

So I’m not sure if that is reducing the input suction significantly.

Any help on getting this to work is appreciated,
Terrence Brannon

easy simple cheap free floatation tank plans – version 2b

Pratyahara Tanks is the worlds first completely open source tank manufacturer. Our tank (known as the Black Beauty) is constructed from 100% off-the-shelf parts. Building this tank requires very little carpentry skills – to build a Black Beauty tank is simple.

Here are a lot of photos of the tank.

and here is a video of me using it.

MATERIALS

  1. 2 Norwesco 360 gallon containment tanks – one will hold the water, one will serve as the top of your tank. Dimensions of containment tank are 93″ Length x 69″ Width x 16″ Height
  2. A hydrometer to measure salinity of the water which reads specific gravity from 1.0 to 2.0. They tend to be calibrated for 60 deg F, but that’s close enough for our work. You also will need to get the cylinder to hold the hydrometer, which they should have also. Dont get standard aquarium hydrometers because those saltwater tanks only have a spec gravity of 1.025.
  3. 7 pieces of plywood (optional, to put some space between the tarp and the tank bottom – picture)
  4. 2-inch thick styrofoam (optional also – I dont even know why I ever listed this).
  5. A pump/filter system.
  6. 2 inflexible rods – used to prop up the tank top while adding salt. pvc or hard wood dowels 4 1/2 feet long are good – Here is a picture. … this is during your build phase. You may be successful attaching drawer guides (glides) between the bottom and top tank so you can slide it as shown here but that approach did not ultimately work for me. So I drilled holes and used plastic cinches to connect the bottom and top parts.

STEP-BY-STEP-INSTRUCTIONS

  1. The base of your tank is a tarp, some 2x4s and 2 inch thick styrofoam.
  2. Then you put down one containment tank
  3. Put the 2nd containment tank on top of the first – picture
  4. Drill holes in both tanks and slide a cinch through the holes to make your hinged door – here is a picture and here is another.
  5. Fill the tank: start with just a few inches of water, enough to cover the heaters. Let that get up to 94 deg F, making use of an external thermometer as reference point. Then add more and more water. But never more than 250 gallons total. See the calculations for how to convert inches of water into total gallons as a function of the tank dimensions. UPDATE: a baptismal heater doesnt need all of this coddling: it can heat very large bodies of water easily. Also, I tend to simply get hot water from the shower and then dump salt into that.
  6. Salt the water. Slowly. 1 bag at a time.
  7. Unplug all electricity and float

CONCEPTUAL TANK DISCUSSION

The Tank Room

A nice tank room that can be comfortably heated is wonderful. Here are other things to consider about the room itself.

electricity

Here is a formula:

watts / volts = amps

since most houses are 120 volts and 15 amps, this implies that you can pull at most 1800 watts of power. So buying 2 1000 watt aquarium heaters is not going to work with standard setups: I know, I threw my fuse breaker when I tried. I have 1 1k watt and another at 300 watts and so far that is fine.

You could re-wire the power from the breaker to the power supply with a different guage wire, or get dedicated wiring, but the purpose of this project is to make everything work with off-the-shelf standard parts and settings.

dimensions

3 feet longer and wider than the tank seems to be an absolute minimum

restroom

A restroom near/attached to the tank room is very convenient.

Tank

Get two 360 gallon containment tanks from NTOTankOutlet.

Tank Framework

Lay down a tarp

You need to get the tank off the floor with some 2x4s. And then put 2-inch styrofoam over that.

Next, simply put the two containment tanks on top of each other like this:

Then drill holes in one side and cinch the top to the bottom on one side to create a hinge like this:

I actually think padlocks are better than plastic cinches because you will find yourself taking them off and on to situate the heaters and also when you drain the tank for cleaning you will need to take off the top. Finally, some people are claustrophobic and would prefer to float without a top.

Spa Pack (pump/filter)

In order to filter the water and warm it, we have to go with a sealless mag drive pump and filter modules.

I’ve found 2 good choices (LifeGard Aquatics and Pondmaster) and I went with pondmaster.

UPDATE – a very good set of articles was published to the Reddit FloatTank group showing a new spa pack setup. See the “Scope for Future Tank” section for details.

LifeGard Aquatics

  • we want a sealless magdrive pump that can deal with 350 gallons of saltwater (though we will only have 250)
  • we a triple capacity mechanical filter for particle filtering
  • we want a triple capacity chemical filter that has carbon in it
  • ultraviolet filtering is loved by some professionals. others think it is a waste of time
  • ozone in a closed space will kill a lot, but might also kill you. So let’s drop that also.
  • hydrogen peroxide will become a good friend of yours
  • weekly and monthly sanitization tips are forthcoming

Temperature Control & Monitoring

Water Thermometer

Submersible Aquarium Heater

In between floats, you need to keep the water warm or the epsom salt will precipitate. So you need a good aquarium heater for that. While 300W is just fine for 300 gallons when you speak of waterbed heaters, my experience is that it is not enough when dealing with aquarium heaters. You need 3-6 watts for every gallon of water you want to heat above 80 deg F. Let’s use 6 watts since we have salt water, whose specific heat capacity is lower than plain water. But on the other hand, you can only have about 1800 watts of total heating at the max. I suggest 1300 to 1600 watts of total heating power. So you’re going to need two 800 watt heaters, one 800 and one 500 or one 1000 and and 300/500 or some combination like that.

Now, there are 7.5 gallons of water in a cubic foot. And so we have the various gallons of water that we can deal with based on total wattage:

  • 1300 watts => 216 gallons of water
  • 1500 watts => 250 gallons
  • 1600 watts => 266 gallons

UPDATE: in my opinion baptismal heaters are the way to go although a washing machine heating element might work.

Epsom Salt

Crop Production Services (sometimes aka Agricultural Garden Supply) was a good place for salt. Look for a place that sells lawn fertilizers.

Then setup your spa pack for intake and discharge by adding some piping.

Then heat the water to 104F (the maximum the spa pack is legally allowed to do) and gradually add salt.

Testing for Salinity

You can get fancy and buy a salinity pen, but you can also get the job done for just 10 bucks with these two products:

Filling the tank

First, start with about 3 inches of water. NO SALT. Then submerge your two heaters. Make sure you can get that up to 95 degrees.

Your maximum height is based on how many gallons of water you can heat. Let’s say you can heat 1500 gallons of water. Since there are 7.5 gallons of water in a cubic foot, we can use unit cancellation mathematics to see who many cubic feet of water we can heat:

(1 ft^3 / 7.5 gal) x 250 gal = 33 ft^3

Now the tank we have it quite wide, so the water will not be very high. Let’s convert cubic feet to inches and see how many cubic inches we can afford to heat. 33 cubic feet is 57,024 cubic inches. Now the tank slopes, but the given width and length are 93″ and 69″. So let’s multiply those together and divide that product by 57,024 to get the height available to us. The result is 8.8 inches. Most people recommend 10 inches, but I think we can get by.

Let’s do the 1300 watt calcs

216 gallons is covered by 28.8 ft^3

1 ft^3 = (12 inches)^3 = 1728 inches cubed

therefore 28.8 ft^3 is 49766 inches

So we have 7.75 inches of water available at 1300 watts. That’s not very high. I’ve done it, but dont recommend it.

General Comments

Total cost

  • two containment tanks: 655 + 190 S&H = 850
  • spa pack with mechanical filter, no ozone: 400 + 50 S&H = 450
  • submersible aquarium heaters – 360 + 9  S&H = 370
  • water thermometer – 8.00 + 7 S&H = 15

The total cost is 1700.00. Most tanks will run you 2000-3500 used. Then we can add in epsom salt for 300 bucks for a clean 2 grand for the whole deal!

Optional Products

You might want a shockbuster, although you will probably opt to float with all heater power off. I was influenced by Tim Strudwick in this case: he built a tank that costs 5 figures and it has NO heat on during the float. So: the heat and pump/filter for my tank are manually added and removed to the tank when used. No fear of electric shock with this approach.

Scope for Future Tank

An excellent pump filter setup was revealed in these 2 posts

  • https://www.reddit.com/r/FloatTank/comments/1871kql/zen_float_filter_bags/

In short

Iwaki MD15RLT Water Pump

I located this pump – https://premiumaquatics.com/products/iwaki-md15rlt-water-pump-japanese-motor.html

since it is mag-drive, can we presume it does not have a rubber seal that can rot due to salt?

I read in the description Includes 1 meter power cord, but you will need to purchase a grounded plug to wire onto it. -> does this mean you needed to do something other than just plug it into a socket?

Inland Seas Nu-Clear Model 533 Mechanical Canister Filter

located – https://www.marineandreef.com/Nu_Clear_Model_533_Canister_Filter_Inland_Seas_p/ris00533.htm

it says it is for salt water up to 90 gallons. How many gallons of water are in a Zen Float Tank? My guess is 200… but typically products can do more than they advertise.

I guess there is a way to know when to replace the carbon filter?

The description says Includes pressure gauge -> what do you use this guage for?

an experiment in contra-survival floatation

I’m experimenting with room and tank temperatures to find the optimal mix. Room temperature was 90 deg F and tank temperature may have been 95.3… my thermometer needs calibration but it did feel rather warm, instead of that usual tepid slightly chilled temp I’m used to.So I get into my tank (which only has 16 inches of clearance to the top) and it’s a pressure cooker. It’s hot and uncomfortable. I make notes to drop the room temperature to 80 deg F next time.

But now for some fun. Is there some way to enjoy myself while my body is sending distress signals about being in sub-optimal conditions? I tried a number of techniques:

 

  1. radiate loving-kindness to the sensations of heat – hmm, I still felt agony
  2. expect the unexpected – I cant send my attention elsewhere, I’m suffering!
  3. observe the sensations with bare attention/equanimity – hmm, man, look. it’s hot in here. and that’s a fact
  4. radiating loving-kindness to the feeling I AM – Eureka! This is truly an amazing technique. Sri Siddharameshar gifted Nisargadatta Maharaj with an excellent tool. It really goes to the root of all problems – the idea that I am a separate entity.

Nothing like trial by fire to see which meditation technique owns!
