What is Reddit's opinion of Rubbermaid Commercial Products Brute Trash Can Dolly with Wheels, Black, Transports 20, 32, 44 and 55G Brute Containers?

From 3.5 billion Reddit comments

hey,

for starters, you should be able to find a 44 gallon brute. Then you could do at least 40 gallons. I have an older one, and a new one, and the older ones seem to be thicker more durable than the new ones (sadly). So, I might think about doing 2 of them. I also paid for a wheel dolly type attachment (they have them at home depot) to put the can on, this way I can make water in one part of the house, then slowly,gently push the can full to the tank to a water change.

Another option is to setup a tank in your garage or somewhere out of sight, and use that for mixing salt water and get a good pump and some tubing and run a long hose to the display tank. you should be able to pick up a used 75 gallon for WAY cheaper than a big plastic mixing tank. of course, this depends on where you live and what the weather is like, I couldnt do it here in florida, the water would get way to hot in my garage in 24 hrs.. but maybe you live somewhere cooler and could just use a heater on the tank?

If you dont like the idea of a glass tank, you could look at the rubbermaid water troughs for horses . they sell them at tractor supply for pretty cheap, i want to say like a 50 or 75 gallon for about a dollar a gallon..

I would guess you have a 75gpd membrane on your RO, that would mean it would take almost 12 hrs to make 35 gallons. sound about right? then maybe you need to do a piggy back RO, where you run the waste water from your first membrane into a second membrane. This should double your output if your pressure is good enough (check your pressure, I cannot do this in my setup, I only have 50psi at the membrane, and what i hear is that you need more like 60-65 to get the 2nd membrane to work right).

edit: some links, and forgot to mention, only use GRAY or WHITE (maybe yellow) brute containers, other colors are NOT food safe and can leach color into your water. They need to be "NSF42" I think, to be the right ones, the old ones were marked this way, and are used in the food service industry and are generally considered reef safe.
