SUMP-I bought an AA sump from Craigslist (48x24x18ish). When I picked up the sump I saw, Jose! The dude with the dreads. That was a cool surprise, I had seen him around the SCMAS meetings. Also, 2 years ago at the SCMAS x-mas dinner he moved so my wife and I could sit together, that was cool. I don't know if he remembered or recognize me. I was totally going to try and talk him down like $20 on the price of the sump but after I know who he was, I decided to keep my mouth shut.
It was a basic sump with 2 chambers so I bought some Acrylic from Paragon Plastics and customized the sump. I cut the plastic to size and made the chambers I needed. From, water in sump to water out of sump, skimmer, refugium, return are the chambers. The sump holds about 50gal of water, working volume. That was kind of my goal just cause my old tank was 50gal and I just wanted to say that my sump holds the same amount of water as my old tank. It makes me feel awesome saying that cause it gauges how much more water I have in my system. Not that I have the biggest tank in the world, just a measurement of old tank to new tank and the possibility of 3x more see life in my house is an awesome feeling.
