I just got my 37gal.tall tank and am wondering how I should set up.I plan on going kinda slow with this one.I'm not sure if I can drill it(the bottom said tempered but i think I've read sometimes it's only the bottom)gonna do more research. If i can't I was thinking a HOB overflow box but read these can be a hassle,and I don't think HOB filter and skimmer will be good enough(correct me if I'm wrong).I have 2 tanks now a 75 w/sump and a 55 w/2HOB filters and a HOB skimmer so I know how to deal with either.I want to add a bunch of tonga branch(still looking for a good source) some seagrass maybe some seafans and (though I'd like to go all natural)some plastic branching coral (I think these will make good hitching posts). Thanks for the help. I will try and get some pics of my build.
