I might be... but not excessively.
Nitrates are at 0, and I only dose 5-7mm of vodka a day. The clean up crew is terribly small, I think stuff is just getting stuck in places snails would get.
Also my skimmer has been working extremely poor over the past few months. I dropped our DCS300 and while it was broken (now fixed and on our frag tank) I bought a Regal 300SSS. From day one I couldn't get it dialed in.
Turns out the pump wasn't strong enough for the body, have to run water up about 3/4ths of the neck. Half the time it would overflow or not collect.
Reef Octopus has a new controller in the mail that bumps up the output from 50 to 70 watts and should run 40% stronger. We'll see if the skimmer starts working correctly after that.
It's weird, the GHA will go away, then just come back.
Also I noticed the fuge was COVERED in GHA, basically the walls of a 36x24" area. There wasn't any more room for it to grow. I'm so over lighting that area, that the walls of the fuge area are probably acting like an algae scrubber and the chaeto in the middle is going wild.
I think if I harvest the GHA when I see it full again maybe that will help as well. It had been full for months... maybe the tank was the next easiest place to grow.
Not to take over your thread, but here is what the fuge looked like after I pulled it and how much I pulled (with the water drained out, decent sized salad bowl):

I have shared your frustration many times with GHA. You should post a video of the new Skimmer and controller in action. Also, how do you like the Neptune Dos doing your AWC. I have to pick one up for this build pretty soon.
Oh, don't worry about taking over the thread. Hell, Im just here for fun anyway.
