Hello everyone, I'm new to this forum and to this saltwater hobby. I have a 24g jbj nano cube with 1 blue damsel 4 turbo and 6 hermit crabs. It's been running for 2 weeks now and the Nitrites are high. I wanted to do water change on it to help lower the nitrites. I add seachem safe ever 24hrs. How much water change do you recommend for this 24 gallon tank? when I'm mixing salt , do i have to match the actual salinity in the tank or it needs to be within the range from the hydrometer? and does the PH matter every time i do WC? any recommendation on how to do it step by step? thank you guys!
