Hi all. I'm hoping someone here can help. For many months, I have been battling high nitrates without any success of remedying it. I've tried several things including the following but it never worked:
1. Large frequent water changes (made no difference)
2. Seachem Prime dosing (which worked for reducing no3 but tanked po4, fried my alveopora, and killed my chaeto)
3. Carbon dosing with sugar (melted my Xenia and stressed out my torch and frogspawn)
4. Reducing feeding (made no difference)
5. Cutting out foods with no phosphorus content (made no difference)
6. Biopellets (I'm at week 6 and it has made no difference at all)
7. Removing the refugium entirely thinking it was eating too much po4 (has made no difference so far)
8. MB7 dosing (has made no difference)
9. Vacuuming the sand bed and accumulated dutritus (made no difference)
10. Dosing Seachem Phosphorus daily at twice the recommended dose for my tank (made no difference at all to my phosphate level)
I have a 150 gallon tall tank (4' x 2' x 31") with a Pro Clear Aquatics model 300 sump, which has x3 filter socks and two compartments. In the large main compartment, I'm using a Reef Octopus Classic 200INT skimmer and a Red Starfish Media Reactor with 600mL of NPX biopellets then a MarinePure 8x8" plate in the second compartment. I feed one cube of frozen mysis twice daily and a small 4x4" sheet of nori once a day. Inhabitants include:
-A pair of Maroon Clowns
-Longnose Butterfly
-Juvenile Emperor Angel
-Flame Angel
-Coral Beauty Angel
-Blue Tang
-Sailfin Tang
-Powder Blue Tang
-Green Mandarin
-Cleaner Goby
Any ideas as to why my no3 is so high and why I can't get it down?
