How do I seal overflow holes?

[waytoodeep03]

I would like to be able to close up my overflow holes and just use HOB filters. My landlord is scared of the sump idea and having running water so close to the carpet.

So I need to close them up for the time being and just use HOB filters.

If its just temporary how about plumbing test plugs? You can get them for a few bucks at the hardware store.

Are they acrylic or glass? If they are glass, just silicone a larger piece of glass over the holes. If acrylic, I would look at plugging them. either plug with the ones show above, or get a threaded bulkhead and put a screw-in plug in it.

If your tank is acrylic, you take a piece of acrylic that is bigger than the hole. Use acrylic glue, it sets very fast, and glue the piece of acrylic inside the tank covering the hole. The repair job can be covered by something, (plants, decorations, etc...) or you might not even notice it. Hope this helps, The Doctor.

hMm tape...? i would be a bit skeptical of tape.. but hey, i dont have experience with that...
yea for glass, i would silicone a glass piece alil bigger than the hole and silicone it together... for acrylic, same method but with acrylic glue.. i just covered up an overflow hole at the upper left side of my 40g... works great!

I would not even consider a permanent solution, like welding acrylic.

Just get a male threaded bushing, a female threaded bushing, a gasket, a threaded cap, and a threaded nipple from homedepot (or lowes which is superior to HD for plumbing). From top to bottom it would be like this:

Cap
Nipple
Male Bushing
Gasket
Tank bottom
Female bushing

come on guys, figure out what he has first- http://www.monsterfishkeepers.com/forums/showthread.php?t=211292

sounds like your not too handy way too deep, no offence. simple solution is dont fill the tank up to the overflow, OR glue pipes into the bulkheads inside your overflow box and have them extend higher than the top of the tank to ensure no water can get in em. there are other ways, but this seems to be the simplest that i can explain over the net.
