For those who don't know, I mix my own water for my tanks. I fill 3 5-gallon jugs with store-bought ro
water, and put all that water into a big plastic tub, add the required salts and other additives, and let it mix with a small powerhead and warm up a bit with a small heater.
I currently use a small powerhead to mix the water and then pump it back into the 5-gallon containers using a hose attached to the output. I then lift the containers to dump water into the tank.
I want some kind of pump that's strong enought to pump water out of the plastic tub and directly into the tank. It also needs to be something inexpensive, since I'll only be using it for water changes. What are my options?
