What’s up everyone. Got an Innovative 25lagoon ext running about 2 months now. Rock was established from an existing tank before I upgraded. All that’s new is sand. Can’t seem to keep any phosphates detectable. Not running any carbon or skimmer just filter floss. I feed pellets about 3 time a day and I have 4 fish . I’ve been dosing a bit of phos from brightwell. Anyone else have this issue before?
