How big are the holes in the UGF? How many and what's the spacing between them?
From Liam's post on Shrimp now
As far as the UGF is, the first row (closest to the inlet) the holes are 2 inches apart, I used a 4mm drill bit. The second row (farthest from inlet) are 1 inch apart, in a hope to equalize the input throughout the entire filter. I have 3 of these homemade filters and I'm quite happy with the performance of all 3. I have had absolutely no clogs in the last 6 months, and no slowdown of performance either.
20g platy, , 2 x 10g shrimp, 3 x 20g shrimp, 7.5g shrimp and 1 great dane/mastiff puppy.
Is this another one?!?!? I see you're using Akadama this time. I'm going to have to check it out one of these days. We still have to hook up...got something for ya! You and Nick make me want to set up a new tank....maybe after the holidays....
