The main reason for the purchase is, I have been fighting GHA for a year. This problem, never existed till I bought a ReefBreeders Proton 32. Even changed the stock white meds to 10k and 20k. No fix. just a few months back I sold it and got 2 Kessil 350w. I lost the control part, but I plan on getting a APEX in a couple weeks so no biggie.
Since then I have removed the sand bed I had for the past 2years,and now is BareBottom. My sump is just filter sock, which I change every 3 days. My Seaside Aquatics cs1 skimmer, and Foam pad then return pump back to Tank.
I have turned back lighting to 5-6 hours, and I just have 2 clowns ( which I feed now 1 cube of mysis a week ,rinsed with RO) (use to be 2 cubes). also mixed LPS and 2 months, and some softies. I lost all my coraline algae in the tank.
maybe my live rock is leaching it back or something. This Monday when I am off, I am going to take a stiff brush to the rocks and rinse, and soak my mp10s and scrub as well. I have even tried blackout for 4 days, but it still comes back.
I do and have been running a bag of chem pure elite, that is in the first chamber of the sump that has a small powerhead for water movement, but not directly on the bag.
I use RODI water from my LFS, and have even gone to 2 other stores to get RO. They use reef crystal salt. which I plan to change to red sea pro this coming week to buy from BRS.
