Well the tank is really starting to go down hill. All of my sps is pretty much gone and I even lost my fire and ice zoa colony. And the tank is silmed up pretty good. My lps and shrooms are doing ok. But nothing seems to be growing. I test my water once a week and it stays about the same. For some reason I can't even get any coraline growing. I did make one mistake and that was I went on a hunting trip last weekend and left my mom in charge of my tank./site/DesktopModules/NTForums/themes/_default/emoticons/cry.gif Well the jug of water that I use to drip fresh water for my top off ran out and my salinity went way up./site/DesktopModules/NTForums/themes/_default/emoticons/crying.gif So I know that didn't help matters. Stupid mistake on my part./site/DesktopModules/NTForums/themes/_default/emoticons/blush.gif I know you guys are going to want to know what my water tested at so here it is: Calcium 420ppm Phosphates 0ppm KH 10dKH Nitrate 5ppm PH 8.2 salinity 1.026 RO 2 tds I dose Purple up every day and dow flake once a week. I do a 5 gallon water change once a week. As far as equipment goes I have a 40 gallon breeder with a 20 gallon sump with a Quite one 800 for a return pump. I run a bak pak for a skimmer. I know its not the best but it will have to work till I get a better one. I have 2 #2 Hydor Koralias for flow in the tank. For lights I have 2 175 watt metal halides. With 20k XM bulbs (I know not a very good choice for growing stuff). With 2 PC actinics. In my sump I have a layer of sand and some LR with cheto. I have a 150 watt metal halide over my sump. Well I don't know what else I can tell you guys. If I forgot anything let me know and I will post a answer. Well hopefully I can get it figuered out cause I'm about at the point of just tearing the thing down and be done with it. Thanks for lookn'.
