Hi guys, a while ago I had bought an used Skimmer from a 3reefer. It worked 'ok', but since skimmers are temperamental, my mother would sneeze and the skimmer would shut off. Me being in college, did not have the ability to come back and fix it and mom says " I only agreed to feed and add water ". So my tank would go months without skimming. Having a FOWLR, this wasnt a HUGE problem (albeit I've always ran my tank in the higher level of stock). Long story short, Im back home and skimmer had been off for 2 weeks. (since I last bought my LEDs and new fish). I tried washing it, but I think this time is dead for good. (there is a needle thing in the pump that looks like its broken). It made some crackling noises and then never turned back on. My zoas are dead ( although having a flame angel, he might be the suspect- they were tiny frags so im not TOO bummed). I havent been reading and I've forgotten quite a bit of things. So please take a minute and enlighten me. Having a Skimmer with high Bioload is important because it removes organic materials which in turn should maintain nutrients that give rise to Nitrates, Ammonia and algae to a minimum correct? My Nitrates have been through the Roof lately (i keep getting red on the kit). I've done a few water changes, but no changes? (3----35-40ish gallons each) My tank is 150G. Most importantly, I am going to purchase a new Skimmer ASAP. I believe the one I have was rated for 180 or 220 I forget. For a fully stocked, possibly over stocked lol 150G tank with a 55G sump/fuge. How big a skimmer should I get? I read some threads and people say to get something rated around 220-300? I've heard Octopus is great, how true is this? Do you guys think that having a skimmer running 24/7 will eliminate my nitrate problems? (I am also continuing water changes and twiking my amount of feeding). For those of you who dont know, here is my current stock in the tank. 5 Batfish, 6 Chromis, 1 Garibaldi, 1 porcupine Puffer, 1 saddle back Clown, 1 yellow tang and 1 sailfin tang, 1 Flame angel and 1 Foxface. I was thinking on returning the saddle back and purchasing a pair of Maroon clowns and call it. Ofcourse since my tank is already stocked to the max I will probably refrain. Unless you guys think it might still be ok? I feed around 6 Cubes a day. (3 of them the puffer swallows whole) and the other 3 is for the remaining fish. Given the metabolism of the remaining fish, Im reluctant to reduce feeding. I know the thread is a mixture of Skimmer and stuff, but the main question is skimmer choices.
