My tank is a 90 gallon and I change 20-30 gallons about every 6 weeks. I can draw that much since I added the 25 gallon receiver tank to my RODI. I need to take the sink spout off my RODI and change filters before my next water change, but I just did one after reigning death on my tank. I'll let my new critters settle in before I do another change, it'll be at least a couple weeks.
I don't have a refugium, so I really rely on good water and good salt to keep my nerves from fraying.
