I've added a step(s) to my 10 gallon shrimp tank that has helped my survival greatly. I'm using RO/DI remineralized water and letting it sit out for 24 hours with an air stone and a heater. I then drip in into my aquarium. This has helped with stress on my shrimp and allowed me to control my water quality a lot more. I've been thinking of adding a similar step to my water changes on my 55 gallon. Currently I use the Python system, but that means adding chlorinated water directly back to my tank after pretreating with Prime, which doesn't sound idea for more fragile inhabitants. I don't think I would start with RO/DI yet, but aging the water does seem like a good idea. If you do this, how do you typically go about it? Buying a 20-30 gallon bucket seems pretty unwieldy, and I'm not sure I could easily get it elevated enough to siphon or drip it in. Anyone have any tips for 20-50% water changes on a 55 gallon?
