Remove and replace overflow. Advice and suggestions please.

[pbauec]

I just got a good deal on a 90G. Its my First tank and I want to do it right and not tear it down and rebuild in 6 months. I have two main issues now. I hate the overflow and drain so I need to remove the glass overflow and plug the existing drain. Then I need to install a new draining system. The baffle is 1/2 glass and I don't think I can remove the silicone without damaging the side corner bead. Would using a diamond blade dremel cut it down to an inch? Something sand would cover? Any other ideas or suggestions to remove it? Next is the drain. Herbie overflow? Any other recommendations? Like I said, I really would rather do the extra work now and a teardown and rebuild later. I welcome all ideas and suggestions.

Oops. Just noticed it was a 90g. Scraping that will be a pain in the butt.

Cut out that piece of overflow material (with a razor blade) and scrape the glass clean (with a razor blade.) Plug up that hole in the bottom corner using a bulkhead and plug. Now install a Glass-Holes overflow and you'll be happy.


I too have a custom 90 with a 1500 gph Glass-Holes overflow. Couldn't be happier. Very small compared to those corner behemoth overflows they make.

+1 ^^^ Just use a razor blade it's a piece of cake (don't know why everyone's making it seem difficult) and nearly impossible to scratch a tank with a fresh blade. P.S. razor blades are one of if not the best to use for scraping algae and removing silicone.

I was afraid of not sealing the tank properly after, not scratching glass. I am paranoid of leaks. But i see its only way to do it. So what recommendations for new overflow and drain system? And should i use a plug or glass over the old drain ?

Not sure why your paranoid about leaks, the silicone you need to remove is only holding the baffle in place not the tank together. Your making this harder than it needs to be. If you accidentally remove some of the structural silicone just add more it's really not hard man. As for the hole, I would cut a circle of glass that fits in the hole then sandwhich it with two square glass pieces. For the overflow I would go bean animal. Just my opinion

The bead on the inside of the tank actually just protects the silicone joint. It doesn't do much to hold the tank together. I've seen people cut it out to re-apply a clean bead when it gets all torn up from years of tank cleaning. Just be sure you let it cure for about a week before you fill it, to make sure it is completely cured. If you can put your nose up to it and smell silicone, it is still curing.
