there is the possibility that your system is under filtered.
How much livestock is in there and what are the specific filters you are using?
you should consider adding a protein skimmer to the set-up. That would also help.
I buy premixed saltwater from a local fish store and I test each time.
I have royal gramma, two anthias, blue tang, maroon clown, kole tang, yellow wrasse, long nose hawkfish, dwarf lion fish and a few snails and crabs.
One fluval 306 canister, one fluval aquaclear 110, uv
sterilizer, reef octopus skimmer, one circulation pump.
