I'm proud to announce my first DIY sump/fuge :)

.... Short buffles are 8" tall. Longer buffles are going almost all the way to the top so i can rest the light on them
I bought precut acrylic sheets (14" x 10") @ Home Depot, so i only had to cut few inches from both sides as opposed to buying big sheet, i think its more handy

Nice job.... thought I'd share a variation on a theme. I'm amazed you're not losing more water through evaporation... I'm putting about a gallon in per day... but I'm moving the water ALOT.... 900 Gph! And you thought you had tight quarters!

Hey guys,
This is a really nice thread! I wonder if anyone uses a UV sterilizer in their system? I'm building a sump/refugium and plan to use a skimmer and a UV sterilizer. I just don't know where in the stream to place the sterilizer. Should I place it after the overflow and before the skimmer?

Usually there is a limit to how much water should flow through the sterilizer. The slower the flow, the more contact time anything will have with the UV bulb. So it would probably need to have its own pump to move water through it, or the return line should be split with some water going through the UV and then up to the tank, as well as the second line that sends up the rest of the water up to the tank.
The only drawback I can think of is when the return pump is off, any water in the UV would drain back into the sump. I don't know if that would burn up the UV or not.

Thanks all - for a newb at sumps, I'm still trying to gather as much information as possible before starting the project. Now I understand the evaporation issue much better. I always assumed the water in the sump would evaporate equally among the chambers, but I see that is not the case. And again wojo, nice job you did there. . .

Good. I hope you read "What is a sump?" because that is really what you need to understand. It explains the refugium as well.
Once you've got that understanding, you can come back to this forum and post your plans as well as any questions so you can DIY - which is something you can be proud of.

Thanks melev, that makes sense to me. BTW, I've also read your site and it's very informative.
Not to hijack wojo's thread but I'd like to make a couple of other observations: I was a reefer back in the dark ages of the mid 80's and things are quite different today. I stopped in 1992 and started again in 2005. Before 2005, I'd never seen a refugium on a reef system. State of the art in those days was a wet/dry system with a skimmer and ozonizer, which I had. The sand/gravel bed (dolomite) was heart of the bacterial filtration then. We simply looked at live rock as just that...rocks w/things growing on them. RO water was a luxury that most didn't have. I used tap water fed to a mixing bucket via garden hose (the HORROR). My nitrates were always low but I'm sure that water was horrible. We knew lighting was important but the stuff available today was unheard of then. Most people frowned on anything under 30-g for a marine tank and you were considered a fool and fish murderer if you tried anything in the nano size. We knew water turnover was good but not necessarilly water movement in the tank. Propogating and fragging corals was just not done either. Ahh, knowledge is good.

I like your sump too! It looks a lot like mine.
One thing about your skimmer... The input to the skimmer should be in the first comportment where the dirty tank water first comes in. The output from the skimmer should go into the next section so as to not recirculate the skimmed water.
You should check out this thread about refuges.
Looks great!! :thumbsup:

Because your tank is draining water into the sump faster than the skimmer can push it out of itself, plenty of water bypasses it. You aren't reskimming the same water over and over. And even if you were reskimming, once the DOCs are out of the water, the skimmer stops producing skimmate.
