300 gl project

Recommended Posts

So I picked up a used 300 gl acrylic aquarium. It's 8' long 29.5" tall and 24" wide. The returns were cut in the bottom so I'm thinking of getting a wider than 1.5" circle of 1" acrylic and welding to inside of bottom. The holes are about 4" off the back. Looks like I have a lot of work to do. Will know more when I get it cleaned upad1a3d11f6a55874dcffd9c5a96f3cac.jpg

I just ordered a 12x12 inch sheet off Amazon for pretty cheap Fred that could be cut to plug the holes easily. Or you could just bulkhead them and put a valve on them as well and use for drains or a closed loop as well.

I paid less than $25 I think for both a 12x12 sheet of clear and a tube of 16 solvent but it was not weld on brand. I would just cover the holes and not try to get an insert to fill because a flat piece will be easier to get to seal. Probably just do a 5x5 or 4x4 patch which would be over kill but give you plenty of surface for a bond even if you are terrible at it like myself.

I'm going to creative acrylics tomorrow to get a patch for a sump I just picked up. He said just a few bucks.

Anything I can cover a 1.5" hole with. Probably 2"or more. Pretty sure I still need to go with 1" thickness

I honestly think one inch thickness will be overkill. The reason they make the tanks that thick is the large expanses of acrylic like to bow so they make them thick and use the euro bracing to keep them as rigid as possible. The about of pressure exerted on any one spot won't be enough to cause any issues. I would think quarter inch would be more than enough and I would go for more overlap that I would go for thicker patch. If the coast is negligible between the two and you are going to have sand then go for it but if the cost different is large I think you could save the money and be perfectly safe.

I think thickness is irrelevant if cost negligible.... So I'd go 1" as long as you have the surface area and a good bond. Unless I missed it, why aren't you using the holes?
