what is safe to plug a hole with

[tgriffin]

I've got a corner aquarium with a built in sump that is behind the DT. It is a lot like some of the nano tanks that have the sump behind the display. The guy that owned the tank before me drilled two holes to allow a maxijet to fit inside the sump and have the nozzle through the hole pointing in the tank. I am wanting to permanently plug/patch that hole. It is round and is however wide enough just to fit a maxijet 1200, so maybe a 1/2 inch. I was wondering if black tape would be safe to fish and corals. I didn't know if that would be best because if figured after some time it would just peel off. I'm wanting something black, as that is what the back of the tank is..


any suggestions

thanks

Don't use black tape. Not only will it not last but it will degrade and you will have the glue and other nasty stuff in your water.

I would patch it with a small piece of acrylic and weld-on.

Assuming the tank is dry, that'll work great. If it's not, use underwater epoxy putty. It should be easy to form a ball of it into a plug to cover the hole.

does the underwater epoxy putty come in black?

I've seen it in all shades of gray and pink/purple but never black - though it may exist. You could always use it to glue a piece of black acrylic over the hole, though it doesn't hold well to acrylic - scratch it up well with sandpaper if you go that route.

My aquarium is acrylic, so I am assuming the overflow/sump is acrylic.

Does it have water in it?
If not just patch it and paint it, if not paint it first let it dry the and the patch with underwater epoxy, just an idea.

it does have water and livestock in it

Try finding a plastic hole cover at the hardware store. They sell different sizes and colors. Most have small tabs that will snap in place, a little water may leak past but won't matter.

I think putty is your only option with water in it already. You could empty it, dry it and use a piece of acrylic as mentioned above to seal the hole.
