I have the R-200 sump and I'm very happy with it. I know they're easy enough to make, but I really didn't want to go through the learning curve on my fuge and I got a decent deal on ebay for $179.00 w/free shipping.
One thing i don't use is the sock. This is my first sump, but I've read a number of articles that state the sock can become a nitrate trap. I'd rather have the detritus stay in motion, so it can be pulled out by the skimmer. Plus.....it's another thing that needs constant maintenance, which I'd rather not add to the list.
so I've heard/read anyway. Again...I have no actual experience with the sock causing nitrate problems.
I just have flex tubing running to the bottom of the first compartment, so I don't have the noise of water splashing of course.
It's a decent product that keeps my nitrates at 0, which is what i bought it for. I will however say that it's not nearly as pristine looking as FDShoes fuge. Props to you on that picture perfect fuge. wow....it's like an ad!
