Just an update:
I completed a 15 gallon water change yesterday and added some LR that had finished cooking. I'll do my best to make 15 gallon water changes every week. I also tore out about 5 handfuls of dead/dying halimeda and caulerpa. I'm waiting on my Ca and Mg test kits, as well as some supplements. I also decided to skim wet for a while, see how that works.
My wife and I have made the decision that if the GBTA does not improve over the next 2 months, we'll breakdown the tank. I foolishly thought I could create a "low-maintenance" reef tank, but I've ended up killing more critters than I care to mention. The idea of what I wanted simply cannot be accomplished without more time and money spent on the tank. Unfortunately, both commodities are in short supply these days.
I'll keep this thread updated, and if it comes down to it, will post a for sale thread in the next two months. Zambavi has first dibs, as I failed to purchase a couple items I told him I would buy.
