    Right now, my 90 gallon aquarium doesn't have a internal overflow. Also, I got the tank from some cheap people :doh: and I got a huge discount on it, so I can't get a refund on it. So, I called 2 people. One told me to tell me to get a hang on overflow. The second told me to get somebody to...

    I just got a 100 gallon sea clear tank. It is pre-drilled. The tank does not have a built in overflow section. Is this necessary? If not, any pro/con for design (durso/stockman) Thanks!

    After many, many searches and no real direction towards what I'm looking for I've turned to the forum. I'm looking for the black plastic trim that is being used on alot of new tanks today.
