Hahaha... thanks for your compliments!
Very satisfied at the skimmer's performance so far. Perhaps, also one of the factors that my sand bed is kept cleaned. I think the re-positioning of the Hydor Nano and the re-scape helped in the overall flow as well. Less build up of detritus. I was thinking of converting the other, now defunct skimmer, into a denitrator. Time to put on my thinking cap!
