Didnt know you owned a dd...that pretty cool so you like it ? What are you using for filtration....i know nothing about sumps or wet/dry sucks i would just throw a couple of 2262's on it and be done
Shadow what are you using for filtration?I have a glass cages tank that I like a lot. Bought it used at 2 years old.
Its a custom size 7'x3'x26" 340. 1/2" glass all the way around. The euro bracing is a little obnoxious but if you use substrate you could just bury it. The other complaint is they could be a little cleaner with their silicone work.
