Water changes? What are those?
20% every other week, 10% the other week with an electronic refractometer.
Don't bring that up lol :banghead:
40g a week for 300g system
I believe in larger water changes with the water going in at the same temp and salinity as what's coming out. Smaller intermittent changes while they don't shock the system as much, don't accomplish the same as larger changes (based on volume calculations). Somewhere on RC I saw a calculator in a thread somewhere validating this method with stats on what percent a 5g WC would do verses a 10g etc.
