How to cap pre-drilled holes

[LordBarron7692]

Not sure I'm putting this in the right area but here goes. Anyways I recently bought another 90 gal tanks that was pre-drill but unlike my other tanks the holes are drill in the bottom right corner as opposed to the center of the bottom glass and it doesn't work with the stand I had built so now I'm just gonna cap it but not sure the best method to use any help would be greatly appreciated and will post pictures tonight for those that "need proof" LOL

How to cap pre-drilled holes

If it already has bulk heads go to HD and buy a cap

[LordBarron7692]

thats the problem the guy that I got the tank from kept them so it's just two holes in the bottom of the tank

[mistahoo]

He kept them? What a cheapskate! He should've included it in the sale of the tank. You could always silicone a piece of glass/acrylic around the hole for a more somewhat permanent solution.

[LordBarron7692]

well in moving the tank one completly broke off so he gave me a fantastic discount plus he moved out of state and didn't want to move it so I pretty much got it for free well I helped him load the moving truck but pretty much got the tank filters and lids for free

[mistahoo]

Ah well that doesn't sound that bad then!

[LordBarron7692]

nah I didn't think so either but you say just a piece of glass or can I use like the light diffusers from hd or lowes?

[mistahoo]

Something flat and about the same thickness of the glass or more.

Edit: If you're gonna be siliconing whatever you plan to use to cover up the hole, you wouldn't want anything plastic like or something that'll break if you knock on it or accidentally hit it.

That would be the cheapest way to go. City Pets sells new bulkheads if you want to temporarily cap the holes so that you can run canisters through the bottom if you wanted to.

[LordBarron7692]

couldn't I just plug it ?

[SunnyHouTX]

Yes, you can. What were your thoughts on how you were gonna do it?

[LordBarron7692]

I actually have no idead other than maybe like a cleanout plug from HD or lowes and just silicone around the edges

[SunnyHouTX]

That could work if the fit is good.

[LordBarron7692]

yeah thats what I'm thinking but it has to fit tight but it's a work in progress I realize that this isn't gonna be a tank that gets set-up tomorrow

[SunnyHouTX]

It doesn't have to be super tight, as long as the plug flange sits well on the glass you'll be fine if the silicone application is good.
