Test alk and cal every 3 days. Could afford an apex and trident. Just don’t think all the cheap looking gear is worth it since I have a PH controller. A Hanna KH checker and Red Sea Calcium test kit. I do a 20% water change every 8-12 days. Just to keep sand bed and sump clean of detritus.Know that this is NOT a one size fits all hobby and there will be many different opinions but what do you consider your reef keeping best practices?
For me, a best practice is the 10% weekly water change. (Thinking about to switching to every other week due to rising costs.). Know that there many reefers that don’t change water but curious to what are the best practices for no water changes?
Anyway, hope you will post your best practices and I’m looking forward to learning something new!
