I maintain the aquariums at a local envrionmental education center. I only maintain the aquariums and do not actually stock fish (although, occassionally I am for my advice). Recently there has been a nasty outbreak of ich, as well as possible other diseases. Let me giv eyou a little background on the facility, because this makes upkeep and maintenance very challenging.
The facility is located in Florida, and the building is un-air-conditioned. This means that air temperatures can range upwards into the 90s, or down into the 20s-30s. Some tanks also get a large amount of sunlight in addition to tank lighting. The tanks range in size from what I think is about 70 gallons to 20 gallons. The filtration is rudimentary with only impellar filtration (the kind with the carbon packets that hang on the back of the tank). The local fish and invertebrates range from crabs to puffers to snappers, etc. The only things that I have to clean all of the tanks, are one algae magnet, a scraper, and a scrub brush. This is used for all tanks (you can see how disease can travel easily). Also, often the fish are added to the tanks without quaratine (much to my dismay).
Basically my questions are--what is the best way for me to treat disease, and also to attempt to prevent further outbreaks? I have already lost numerous puffers/burrfish, filefish, conchs, and crabs recently.
Any help or advice with this challenging set up would be great.
Thanks so much.
