Hello, I started lurking this forum and reading the website when I got a 25 gallon tank a few months ago for free, and with the help here got it up and running with 5 Tiger Barbs, 5 Cherry Barbs and 5 Danio's. I was hooked on the hobby immediately, and loved watching my fish (Especially the Tigers, they are awesome.) I knew I wanted a bigger tank so i surfed craigslist every day, hoping to spot a 55 or so to upgrade so I could get a Rainbow shark or something like that. I spotted a 125 Gallon for $50(!!) and called as soon as I saw the post, and the guy also ended up selling me the stand for it, a Mareinland Tidepool 2 wet/dry (only missing return line but did have pump) a HOT Magnum 250 canister and a bunch of Reef chemicals and assorted food and stuff. I got the whole kit and kaboodle for $125. A very good deal if I say so myself. My wife was not as excited to see the 125 as I was, so it sat in my workshop while I decided what to do with it. Then, one morning I noticed my tank was about 3 inches low on water, so thinking it was weird to have such sudden evaporation, I noticed the water running down the stand and the wet floor :-\ Aww , I sprang a spontaneous leak. Beats me how, the tank hasn't moved since I got it. So I figured, I better pump the water to the125 and move the fish there while I reseal the 25. Then I REALLY screwed up. I dont know what I was thinking, but I got a bucket of tap water to transport the fish to the other tank, AND I didn't even remember to treat the water. By the time I caught the last fish out of the tank, I noticed the ones in the bucket were dead I know better than that too, I just wasn't thinking. I should have siphoned out of the tank to fill the bucket. Well I was able to save 2 Tiger Barbs and 3 Danio's, and they are doing fine in my 125 gallon, that is only filled 1/4 of the way. I have a Whisper filter box sitting in the tank for filtration and a couple of powerheads moving the water around, and they are doing fine for now. So that's my introduction, I do have a bunch of questions on setting up the wet/dry system, I need to get some media for the trays, and some kind of return line etc. I'd ask more but I'll save it for another thread, I'm tired of typing now anyway.
