I have read several posts on Ich. I started battling it a week after I bought my 1st Tang (Dejardin). I was feeding with garlic soaked food and soon after started using a product called Ich Attack so as to not harm inverts or coral. I thought I was beating it into remiission as all of my fish seemed to be doing well and spots started to go away, everyone was out swimming and going about daily activities; like eating with gusto. I then lost my Tang yesterday followed with my Signal Goby and 6 Line this morning. Everything looked healthy and normal if I did not know i had been battling the Ich. This is my 1st major loss of any kind in my tank and I am pretty upset about it. I checked water quality and nothing is out of whack and temps are running constantly at 78 to 79 with heater. My skunk cleaner shrimp ain't cleaning a thing. Any advice on better techniques or anything I can do to prevent this next time? I am running an Oceanic biocube 29 (approx. 24 gallons) Near zero nitrites or nitrates. Zero detectable on other negatives. SG is just below 1.025. Any fish to get to help me combat this next time or possibly adding another small cleaner shrimp? Thanks to everyone for any help. JOHN
