How much water do you take out of a 55 down to be 20%
water has a density of 62.4 pounds per cu ft and tank is 36 cu ft 62.4 x 36 = 2246 pounds
There is not enough information to answer. What is the shape of the tank? How cold is it? How efficient is the heating system? How large a space are you heating?
Use volume which is cm3 ? x ? x ? Length Width Depth
To get a specific answer, we'd have to know the size of the tank. Since you used "an", let's assume an 18 gallon tank. 18 x 2.999 = 53.982. Rounded to the nearest cent (hundredth), that's $53.98
It depends on how much water and how pressure is on the tank.
about 4 feet
What kind of tank? How much water is in it? Is there air in the tank? What fills the tank? What kind of pressure from where and what?answerIf the tank is gravity fed, multiply .431 times the altitude that the source is above the tank. For example, the reservoir supplying my domestic water system is approximately 200 feet higher than the valley floor I live on. My water pressure is slightly over 80 psi. If the tank is pump fed, and if you have no information on the pump, you will have to put a gauge on the system.
That depends on how much water is drawn from the tank and how often it is drawn.
10,771.2 gallons with a weight of 89,724 pounds NOT including the tank
the salt comes with a scoop and 1 per gal of water is what I do and it has worked great for me

None, unless it is contaminated.
56.75 Gallons
26500 liters
Be more Specific, Size of tank, temp of water, etc
It depends on the type/brand of conditioner, and how much water is the Betta tank can hold.
