Ok so here is what I finally decided to do after hearing from you all and researching online.
I've decided to go with the Aquarium Master. Apparently their new tanks do use the cross support bar and glass. I'm going with the 135 standard aquarium that measures 72" long x 18" deep x 24" tall. I was going to go with the 120 gallon model but it was only 48" long x 24 x24" and I want the fish to have room to swim back and forth.
If you think the 120 would be best, please let me know cause I'm going tomorrow morning to get it. The 135 gallon is being sold for $279 + tax so $300 here.
The front, back and bottom of the tank are tempered and ONLY the sides are not. So my plan is to drill the left side of the tank that is 18" wide. Is this ok? I really need to know if this will be ok or will it limit me on the box that I can place. I'm looking to drill a bean animal overflow. I guess the returns would have to go on the same side? That way nobody see it it from the entrance when they come in. Is it ok that both the overflow and return are on the same side and close?
Any input would be greatly appreciated. Thanks!
