I wouldnt lower your phos any lower. Corals need phos to flourish. I have mine at .1 right now and am happy with that. Sweetohioreef is experiencing major coral damage right now from several days of 0 phosphates with corals in strong lighting. So be careful lowering it too much. Even with the tank fallow you will need to add food or something for the bacteria to feed off of or your bacteria bed will be harmed. Once your able to add tangs to the tank you will be able to control the gha a lot better. Love the moorish in your tank. Looks like you might have bought Justins fish. When your ready to buy fish send me a pm, I can save you a lot of money.

Very good point Jeff. I read it all over the place that people are so focused on keeping nutrients low these days that they actually strip them entirely, which is way worse! I did receive my high capacity GFO in last week but still have changed out the media with my old yet. I brought online an algae turf scrubber I had laying around from my old 75g and it seems to be working well (pic below is of first harvest). For right now I have managed to curb the gha outbreak. Its still there a little bit but not really growing anymore, whereas before it was growing rapidly. So if I can naturally bring the levels down to a safe spot I think I may just do that. I was also able to find a Skimz MBR127 macroalgae reactor for $92 bucks on BRS! Pump and leds included! It was an open box return + they are liquidating all their Skimz products for 60% off. I figured why not give it a shot, its only rated for around 100 gallons but it will fit in the sump just fine and if I use it with my current ATS there's no need for the bigger one. I have been doing weekly feedings of my corals now that I am fishless and to keep the inverts happy. I feed the trachys, anemone, and elegance each a nice chuck of the rods reef frenzy and they gobble it right up. I also target feed everything else with reef roids.
I may have have to take you up on the fish offer here in a few months
