Hello all, long time since last posted. I have been battling GHA for long time and I am about over it!!!!! It is more than a little bit, has almost taken over. Always have had ULN, always, Do not think that GHA using up nitrate so not in water column. My tank is too clean!!! Here is my plan, and perhaps last ditch effort. Here is my tank stats reefer 170 live sand dry rock AI Hydra 26 HD (blues 60% low red and green white 26%) system 3-4 years old, matured slowly through out rodi Apex apex top off protein skimmer carbon reactor, have been running both carbon and GFO until recently. Dose CA and DKH, BRS 1.1 ml pump on run on apex bio load: royal gramma 1 chromi, (should get more) pulling out GHA and has stress out others that did not make it, so hesitant to get more before GHA under control) LPS and soft coral only CUC: 1 tuxedo urchin 6 astrea 5 narsarius 7 turbo 4 hermits 1 peppermint shrimp (maybe, see him every six months or so, it has been a long time since last spotting) SG 1.025 PH 8.0-8.35 DKH 9.6 CA 460 Mg (typically high I don't test anymore Nitrate 0 Highest has ever been in 3 years has been 3 phosphate 0.02 TEMP: 77.5 WC 2-3 weeks I am sure this is not a high nutrient issue, I have been down that road for a long time. Still have original flake food I bought 3-4 years ago. Here is my plan, curious what people think 1. have been manual removing, hoping if removed would increase nitrates. I have removed a lot of gha nitrate continue to be 0 and P0 0.02. This is steady 2. turning off reactor 3. Skimate always tea color, going to dial back and really just use for oxygenation, not nutrient removal 4. frozen food for fish and increase reef roid 5. track nitrate and phosphate for 2 weeks 6. continue to remove GHA manually 7. dose Nitrate, bright well 8. have phosphate to dose if necessary (brightwell) GOAL: nitrate of 5ppm and continued 0.02 and decrease in GHA Tried to keep post short, hoping people will have feedback. Clown79, I need your help!!!! Thank you!!
