I just ordered a sump tonight. I saw Dace's for sale thread but I didn't really like the configuration. I went with a 48" long by 24" deep by 20" high. The height was just because he could go to 24" with out charging me so I went to 20". I did a simple 6" drain area, 1 baffle huge fuge in the middle 2 baffles before return, leaving 6" for the return area. Basically I went with a monster refugium. The baffles will be 10" high so the sump volume while running is 50 gallons with additional room for 50 gallons of water draining when I shut the system down, although I think i should have under 20 gallons of water draining. I also got 48" by 18" by 10" high rimless frag tank ordered. They will drill it for me so I can plumb it right in. I gt everything at world class aquarium in Brooklyn. It's a really old school store and they build tanks in the basement. The tanks aren't nice at all, pretty sloppy and over built with a ton of braces on top, but for sumps and things of that sort they're good and priced very well. The guy that owns the place is really old school and he wants you to go his way, like a wet dry or what he calls a mud filter! lol But if you sweet talk him enough he actually will listen to you and do what you want lol. He's actually a really nice guy and means well but hes set in his ways. I am expecting a huge Premium Aquatics delivery tomorrow. Once I get that and I have the sump in like a week or 2 I can start plumbing which I wish I could just have someone good do for me but I don't know anyone for the job. I can do it all on my own but i'm sort of lazy with the plumbing for some reason. I am going to have all the electrical and ventilation stuff done tomorrow.
