How to eliminate hole in tank I don't want

[mamia]

Hello I recently picked up a 95 gallon Surfline aquarium that is drilled has all the plumbing for the sump and everything. I don't want to use a some I'm going to use hang on back filters. My question is how do I eliminate those holes? Do I remove everything and get a piece of glass and silicone it over the holes, or do I find a way to cap off existing Plumbing? I tried to unscrew the shredded part underneath the tank but it won't move. Any suggestions are greatly appreciated I'd like to try to get my project underway

Hi, if the seal around the outlet / inlet pipes is water tight I'd be tempted to leave it in situ & just cap the pipe ends.

Hello. I don't know 100% if it is water tight because i don't know how to "plug them up" to fill with water. The pipes sticking out the bottom have no thread until close the the glass. Do i plug them from the inside? I went to home depot yesterday, left feeling defeated. The previous owner said held water, other than cleaning see no scratches.
I kept the top and bottom of stand but trashed the rest as i want to use wood.

One way would be to get about a 6 inch length of hose & push the ends onto each of the protruding pipes & clamp with jubilee clips, you could then fill the inside holes with aquatic silicon to stop water getting into the pipe & stop any fish etc. going in there & getting stuck, I think that should work.

Ok. On my way to buy them and give it a try.
Thanks for your help.

You're welcome, let the silicon dry thoroughly & then put some water in the tank to check for leaks before using.

....clamp with jubilee clips, .....

LOL, first time I heard them called that. Learn something new all the time. That might even be the real name.

I would remove everything from the hole and clean the glass on both sides well. Scrape off any remaining silicone.
I would get a small piece of glass large enough to cover the hole. Silicone bead all around the edge and press onto the glass and let cure for at least 24 hours.
Do this from the inside so all the pressure on your patch is from within.

They do make a product for this. Its a plug made for a water tight seal. Its two pieces with a bolt and a nut. Maybe you can find more than I did. Good luck.

Well.....looks like i will be doing your glass idea. Just came home on lunch to drop off plugs and hose....my son decided to "help" me out..poor thing has be breaking the black "box" out with pliers to surprise me ..it's the thought that counts

Ok. Scraped all silicone off, cleaned with alcohol, tank glass and patch glass. Put silicone on...now waiting for it to cure. Question..patch glass is 3/4" thick, 6"x12". Should i put another piece on top of it or?
Thanks for all the help

Does it look rippled or is it just the shadow?
That is a thick piece of glass!!!

Um..the caulking in ziz zag but when pressed down edges are flat, then caulked around outside edge...should i take it off and do it again?

Aaah, now it makes sense. It may be just me, but the circle around the upper hole looks a little thin in the upper right quadrant. It may be just the perspective.

Good grief. Was just told the glass is 1/4" not 3/4". Should i remove it and reseal it or let it dry then remove it or?
Thanks again for the help. It is a 95 gallon surfline tank if that helps.

Glad you clarified the glass patch piece thickness! I am a perfectionist so I would have done this a different way.
1) I would have used a single bead all the way around the patch piece. Just inside the edges. But far enough in so it did not squeeze out the edges. This would require light pressing. I hope you did not press it hard enough to flatten the silicone bead? If you did you should remove and start all over again.
2) I would have never used any around the edges, outside the patch. The inner bead is plenty.

I did press to flatten, some did, others did not hence the ziz zag look. i agree it looks like and not happy with it. I will remove it this evening and start over.
So i do NOT put silicone anywhere but the inner edges then? I thought i had to cover the whole glass patch (which came out poorly)
Thank you for you help.

Do a little more of you own research on this style patch. With that much water on top of it, ME PERSONALLY, I would want a solid surface butted against each other. Either buttering bread style, or around the outside edges leaving the center glass to glass.

 

[mamia]

I have and did it the way the internet showed
I will figure it out.
Thanks

I did not see your pictures well enough to give you any advice. But I do see your last picture well.
Being the hole is so close to the tank bottom edge, I am not sure a patch is the best option? Google "bulkhead plug" and see what you can come up with.
I was under the impression the hole was further away from the bottom edge. This hole is in a very bad spot. Personally I would not trust any repair as this hole is to close to the bottom tank seal. But maybe a plug will work.

Hello. I did find bulk head plugs online last night. I ordered a set. I am almost afraid to fill this thing up anymore at this point...i will probably just move on to another tank.
Thank you

I agree. I would never trust it. In that place that is. Had it been out away from sides and bottom I might have tried.
