I agree with Flake and Spoonman...the corals are doing fine, they are all open and looking actually better than they did in the tank lol probably because my powercompact is like6 inches from them lol, my engineer goby pulled through, he is swimming around now and I fed everything a very minimal amount last night and he ate almost everything, my LPS'S all ate and shrooms are fully expanded, I did about a 60% water change(i found out that larger PWC's help with my column tank instead of the normal 20% i usually do about a 35 give or tank guess it because it is so tall with a small surface area) I checked my parameters yesterday i have a GH,KH,PH,NO2 AND NO3 TEST KIT, GH-180, KH-250,, PH-8.0 i put in some buffer so it should be highr now, NO2-0, NO3-0. Since there is nothing in the tank except my LR that doesnt have corals on it(60% of my rock), I plan on switching out my substrate monday from CC to LS, I plan on leaving about a half inch to an inch of cc and adding about 3 inches of sand on top of it I just cnt aquascape it until Im ready to put everything back into it due to some of the rock that I removed and with only an engineer goby for fish, my bio load will be next to nothing lol. I have 2 xlrg turbo's and about 6 smaller turbo's, about 5 nassarius snails, 2 emerald crabs, 1 ppmnt shrimp and 4 hermits left so I plan on adding some more cleaners also. on a good note I saw a nass in the tank that i didnt get out and he was just cruising across the bottom, looking for some grub unlike the other day when everything was basically climbing out of the tank, I watch him for about a half hour to see how he as acting and he did not seem to be suffering at all, i have noticed more feather dusters opening up and spagatti worms doing their thing also any ideas of what I should add?1 torch, 1 trumpet, 1 forgspawn, (all single heads) 1 green lobo, 1 green bubble, I purple lobo(he wasnt doing to well when I got him though so he migh be on his way out) 1 yellow encrusting montiora on a frag disk, carious zoos, dragoneyes, some orage and red with white centers and lime green. 12 various msshrooms, 2 orage ricordia, 2 neon ricordias(they are whit with like flourescent green mouthes and edges, about 20 button polyps, 1 baby gonipora, roughy 15 headed black sun polyps
