Million dollar question

[Lori]

So, I bought a tank Pre-drilled. I'm removing the overflow in the tank and want to seal the two enormous holes in the bottom. What do you suggest? 1. Have a piece of glass cut larger then the holes and Silicone the heck out of it? 2. Same as #1. I'm out of guesses. Oh, last question. Instead of everyone doubting the GE1 silicone from lowes or home depot, why not just get the stuff from one of these Custom tank builder's? If it work's for them, it should work for you and me. We'll skip that for now, I just want to know what you would do to seal the holes. Thank's.

I did the same thing you are talking about doing with pvc caps from Home Depot....the silicone will work....I had a tank with 4 holes in the bottom and none of them leaked ...

Ok CF. Splain it to me. You got 4 holes. You buy 4 PVC caps. I assume larger than the hole. Add silicone to cap and glass, apply preasure, and that's it. No leaky? Hmmmmm. I'm scratching my head thinking about this. I've rigged plenty thing but, still scratching head.

[fshfrk]

Use the GE1 and the glass should over hang 4"-6". You should be good to go.

[Lori]

You say that with Confidence. I'm still scratching my head.

key....let dry for a few days....

I used large black rubber washers under the pvc caps...(yes ..oversized) and the water pressure does the rest.....you could use any solid flat object that is water proof....it just needs to be solid....

If John (fshfrk) says it'll work, you can take it to the bank! He is the MacGyver of the aquarium world

Ok. I think i'm getting it now. New question. How do you suggest I cut the overflow box out. Not alot of space between overflow an tank walls. Razor blade may take awhile.

[CichlidFan]

I have thought....mind you I have not tried this......but I had thought about trying a heat gun on the silicone and pulling them off....but....you must be careful not to go crazy with the surronding areas. where you don't want to disturb the silicone on the walls of the sides and bottom.......I believe the razor blade is the "go to" method though...just use patience and be careful......take your time.

how big is the tank?
if i was you, i just sold that tank and buy another tank that fitted your need.

[Lori]

The thing is, I just bought this tank. So, it's a project in the work's. The tank is a 100gal.

+1
Since you already removed the overflow boxes this is the best option to go.

I found some plugs at Lowe's. Gonna try them this weekend. I'll post up some pics before I start the transformation. Maybe it will be helpful to someone like me in the future.

[fshfrk]

I took the reef ready over flows out of a 210gal and drain from the bottom into a wet dry. But thats a whole other deal. I would not plug the holes. There are other options.

[Lori]

Fshfrk, i'm all ears. What are your other option's? Tank has been put on hold until "HoneyDo's" are Complete.
