I recently purchase a used 220 gallon Perfecto aquarium, 72x24x30 tall. I have a lot of questions and concerns about setting this tank up. This tank will be replacing a 6' 125 gallon aquarium I have now.

My first concern is strengthening the floor for the larger tank. I live in a mobile home and the 125 gallon tank sits parallel with the floor joists and has been there for 8 years with no problems. It has bothered me some, even though there hasn't been problems, that it's been sitting on one floor joist this whole time. I went under the house to see how the floor was constructed and the aqaurium is centered on one 2x6 floor joist. 16" to the rear of that joist is a 4x6 which the wall behind the tank is resting on. There are steel I beams 8' on center running the length of the house. Any suggestions on what the best way is to strengthen this floor area to support the larger aquarium that I will be putting there? Putting it somewhere else in the house is not an option. BTW, I'm planning on putting a 55 gallon sump under it as well.

Next, I've read of some people having problems with Perfecto aquariums leaking. Many people said that the silicone joints are very thin and that they should be cut out and re-sealed. I looked at the seams on this tank and agree that they are thin, with not an excess amount of silicone but they still appear in good shape... not peeling. The tank was manufactured in 1990, however. Any thoughts/opinions on this?

Also, I'm planning on ordering an overflow box from Glass-Holes.com. I really like the design of these overflow boxes and they assure me that drilling the glass is not that difficult. Glass is 1/2" thick and not tempered. Anyone have experience with their overflow boxes and/or drilling glass?

Thanks!
 
If you have the time, stripping all the silicone and resealing is about a 3 hour job and about 20 buck is material. It would probably be worth doing just so it eases your nerves. For support I would do something like pictured below(modified ofcouse since floor joist are running opposite). You can also "sister" the existing floor joints by adding another 2" x 6" board to them.

Thanks for the picture. I think I will try to do something similar to that... doubling and maybe even tripling the floor joists under the tank and adding a beam below those.

If I were to reseal the tank, could I just do the four sides and not the bottom? The bottom seams have an ample amount of silicone.

Does anyone have any experience with www.Glass-Holes.com overflow boxes?

No, it is best to reseal the entire tank. The new silicone will not bond to the old silicone, so you could end up with a leakin this area.
