I am currently cycling a 29gal with a 20gal sump. It has been cycling for about a month now and ammonia is at 0 nitrites 0 and nitrates were at 5ppm. Now I am waiting for the phosphate cycle to complete and when gha is present is when I will add my CUC. They will be the first things I put in so is it necessary to continue checking the parameters? Obviously I'll keep checking salinity but since there shouldn't be a change do I need to continue or can I save my testers and wait till before I add my CUC to start checking again?
