Hey all, I have been longing for some SPS lovin' but every time I bring a frag or two home they bleach/go nasty and end up dying in two or so weeks. Abit about my tank, (more can be found in my build thread), its a 55g. Lights are 150Ws of 3W Cree LED's. 30g sump, with skimmer (Hydor Performer 450), refugium (Calerpa + Alternate light cycle), carbon reactor and GFO reactor. 1/6 HP Chiller. Flow is provided by 2x MP10s. The tank currently houses a bristletooth tang, flame angel, two oscellaris clowns, a cleaner wrasse and a court jester goby (Please discuss my stocking choices on my build thread). Coral wise, its mainly LPS (Hammers, Torches, Elegances), Softies (Singularia, Toadstool, Kenya tree), zoanthids and NPS (Gorgs and Sun Coral) + a BTA or two. I have had a few problems with the LPS over recent weeks with a few hammers and torches experiencing polyp bailout, but so far seem to be on top of that now. SPS that I have tried have really only included wild acro colonies, I have also tried a few acro frags (unknown species), a dallas acro, and some smooth skin acros. In the tank at the moment I have a green montipora that I have had for about a week. My current big 3 are: Calc: 350 Alk: 9.8 Mg: 1400 SG: 1.025-1.026 Temp: 25 Degrees Celcius. (77 degrees Fahrenheit) I will take these reading every day for the next week to see if maybe dosing might be the go? Salt used is Red Sea Coral Pro. I do 10% water changes every 2 weeks. I dose nothing into the tank except for Microbacter 7, Prodibio Digest and Coral food etc. I did at one stage used to add a little bit of Red Sea Ca/Mg/Alk solutions, but haven't for a while. But please. Tear me apart, help me out. I really want to get on top of these issues so I can get into some SPS. I will take a video sometime tomorrow specifically on this issue and attempt to post it (but my nets slow so may take a while).
