That is, how many cubic feet is needed for a 55 gallon barrel for a moving bed filter?

A 55 gallon drum is about 7.35 cubic foot. If you wanted 1/3 of the filter to be bead material then you would want about 2.5 to 3 cubic foot. Everyone builds their filters differently but this should point you in the right direction. Thanks for your interest, John

I used three bags to fill my 20L (30in X 12in) tank, this gave me a bed depth of approximately 2.5in. That is about 900 cubic inches of substrate (30in X 12in X 2.5in = 900in^3) roughly that means you will get about 300 cubic inches per bag. So for your 55 (48in X 12 X 2in = 1152in^3) (1152 / 300 = 3.84) I would recommend purchasing purchasing 4 bags of substrate, to acquire a bed depth of 2in. For other bed depths just calculate the volume of the substrate you would like (L X W X H = V) and divide that number by 300 (V/300 = # of bags) to roughly determine how many bags you should purchase. Hope you find this helpful. I used three bags to fill my 20L (30in X 12in) tank, this gave me a bed depth of approximately 2.5in.

6.5" is the overall depth of the body of the filter. You'll need 3" minimum, preferably 4+ inches clearance from top of aquarium glass/frame to whatever goes above, in order to facilitate removing all for cleaning or just removing the filter without having to dismantle it completely. Hope it helps.

I checked on Google and it said there is around 226.5 liters in 8.0 cubic feet.

Umm no. If you have a 55 you should buy a Aquaclear 110. It is rated for a 110 gallon aquarium. The rule of thum is to use a hang on back filter rated for 2 times the size of your tank.

Thanks for your question. I think that a 55gal would be the max tank I would use it for. You would have to use it to the max adjusting but it should work fine. Good luck and have fun

Based on the dimensions given as 20" tall and 16" diameter, cubic footage is about 2.3 cubic feet, or about 17.5 gallons

If your 55gal is 48", like most are, it will work. You will need 2 of them.

1 is barely enough 2 shouldn't hurt I have 2500gph in my 55 and it could take more a good rule of thumb go salt water is "a minimum of 20gph flow per 1 gallon of tank volume" so a 55 needs a minimum of 2100 gph also just watch your aquarium and give it what it likes

I would guess 20 galons of water. There are no drain holes. The barrel is made of fiberglass or some type of plastic resin. It is only around 24" long by 16" wide. Hope this helps

Storage Capacity: 16.2 Cubic Feet (121 gallons); Dimensions: 56" (W) x 22" (H) x 21" (Depth); Outside Dimensions: 60" (W) x 28" (H) x 26" (Depth).

4 Gal. 12x15 works great. I already had a system but wanted something smaller easier to manage. I added a valve and tubing to container for drainage. As well I upgraded my airstone to two and larger ones than what comes with it. I would suggest an extra pump capable of running two to three lines for the airstones and hook up two. More bubbles means more co2 and better roots. Hope it helps.

If 1 lb (453.6 gms) is used to treat 10,000 gallons to 7.5 ppm Cl2 level (per their guidance), I calculate a 55 gallon drum would require only 0.66 gms to achieve 2 ppm Cl2 level.And if that 0.66 gms is 32% inert that comes out to 0.21 gms, IMO hardly worth worrying about. That said most people do not have access to a balance that measures gms accurately, I do. Which is the reason this usage indication generally has you make a stock solution of about 500 ppm to use for water purification.

Mine used almost 4 cubic feet. It hasn't had time to settle though, so I may need to add some more as it does.

I get approximately 4.4 cubic feet. It' a little difficult to do a precise measurement.

To answer your question truthfully... it all depends on your tank and what you're trying to do. You may be okay with a 500. This is my experience with the 750 pump on my 75 gallon heavily planted FW tank. I bought it when I had only one 55/75 aqueon filter because I wanted to circulate the water better. I think for my intended purpose, I bought TOO big of a pump because it kept uprooting my live plants despite it being placed close to the top of the tank and aimed up. I felt like the pump size I bought was too big and instead of buying a smaller size circulation pump, I opted to take it out and buy a second 55/75 aqueon filter. With two filters running, my tank has plenty of circulation so I don't feel like I need to add a circulation pump to my tank. Even though I don't use it in my tank(s), I feel it was a good purchase as I felt it was doing a good job of moving the water and it was quiet. Plus, I still use it occasionally to circulate the water in my bathtub while I'm curing big pieces of driftwood that I can't boil.

My waterbed mattress is working fine. It's a little thinner that the mattress I replaced. The mattress measures 7 feet by 6 feet by 8 inches deep Equals 84 inches by 72 inches by 8 inches Equals 84x72x8= 48384 cubic inches Now convert cubic inches to gallons. There are about 231 cubic inches in a gallon So 48384/231=209.5 gallons 209.5 gallons * 8.34 pounds per gallon = 1747 pounds of water, not counting the weight of the bed frame.
