I am having some very strange issues. Which is part of the reason I haven't done an update. I have lost quite a few corals the past month or so. My PH keeps dipping below 8.0 at night, yet I am keeping my ALK in the 8-9DKH range. I am thinking that this is where my problem lies since it is mostly SPS that seems to not be doing as well, some zoas and for the most part my LPS are totally fine. The weird part is how well my other SPS and zoas that are not dying are doing. lots of growth good color... its very frustrating and confusing. I have been a little extra busy since taking on managing the Lionsgate Center, the event center my parents own. So I have had less time to spend working / looking at the tank which makes it harder to figure out what exactly I need to do to fix this. I think that these problems may be due to the tank needing mature more. I figure more water volume will get you more stable parameters, but will also take longer to fully mature into a true box of ocean.
The good news with the tank is that all the fish are doing very well and I have seem to beat the ich into remission. It had me wondering if I was ever going to be able to keep tangs in the tank. None of the other fish would show any signs of infection however almost every tang I put in the tank aside from my sail fin and blue hippo would get it bad after introduction and would be dead days later. After loosing 2 powder blues and a clown tang I stopped adding tangs for a month or two. I then tried one last time adding a purple tang, clown tang, naso tang, and barine tang. I added them as a group, after the lights went off, and after a longer acclimation than I normally do. I also increased the amount of feedings w/garlic and ordered a pound of gracilaria from catfish charlies so they have a constant supply of fresh algae to eat. That seemed to do the trick! Those tangs have been in the tank for over a month now looking fat and healthy and no signs of ich! (even though I do know its lying dormant somewhere in the tank waiting for the fish to get stressed enough to succum to infection, but I just have to accept that since tearing everything down and setting up an elaborate QT system is just not an option for me)
