Hello, I am very new to the internet world and have been enjoying the Q&A's posted on your site. I have had a 90 gallon marine tank for about 4yrs now and started the adventure by falling in love with a porcupine puffer at my local aquarium store. I currently have a strange "something" taking over my tank and I have seen this a few times before. I have spoken to many marine enthusiasts and no one seems to know what is going on in there, perhaps you will know... About a week ago my fish developed something that looks like ich. I had a bannerfish, clown, tang, 3 damsels, trigger(had for 3.5yrs), and of course my dog face puffer(had for 10months). My water condition is almost perfect except for my PH is a little low 7.8 from 8.2. I immediately started treating them by raising the temp from 78 degrees to 81 and lowered the salinity from .022 to .018. Unfortunately the "ich" or whatever it is got much worse. I lost my clown and bannerfish and my puffer developed a thick white patch between his mouth and gill. I started freshwater dips on him (same temp. and PH) but that also made him worse the white patch grew and turned dark almost like a bruise. I have now seen this bruising on 2 other puffers in my tank and both times no one could help. I finally decided to get medication but didn't know what i was treating. After a long chat with my local aquarium store we decided to treat the tank with a non copper based solution that treats many different kinds of parasites and bacteria such as, fungus, fin rot, ich, etc. By the time i was ready to give the tank a 1/2 dose the bruising took over his body and he died (it broke my heart). He was breathing very heavy, wouldn't eat(for 2-3 days), and it looked like he was urinating a thick white substance. The bruising and the other symptoms are the same thing that happened to my other puffers (a porcupine and another dogface). I have since medicated the tank and by the next morning my fish looked much better but by the end of the day they are covered with white thick spots again. I really don't know what to do and don't want to loose my remaining fish. I would also really like to have a puffer some day but i am very afraid that there is something in my tank that will cause this to happen again. If i can figure it out maybe i can get rid of it. Please help, any advice is welcome. Thanks j_fers
