Hey all, I’m pretty new to this all so I appreciate the help, tank is 7 months old, 75 gallons, 60lb of live rock, 60lb of live sand, I’ve been having issues with nitrates and phosphates everything else seems to be in order, recently added denitrate which lowered my nitrates from 27ppm to 4.4ppm overnight however 8 hours later it was 14.5ppm, phosphates also have been steadily increasing while using Phosphat-E from brightwell, phosphate was at .58ppm last night around 10pm and is now at .71ppm aprox 20 hours later, I’ve been using Hanna testers for all tests if that helps, thank you
