Aww. Guess I will have to call someone for mine.
I have run different water depths now. Had a good 9in. in my 20g sump as compared with 8in. with my SWC sump. Unlike some of the RC thread, I found no difference. Easy to adjust in either situation to run both wet or dry.
This is wet skimming. I either dumped it at lunchtime yesterday or the day before. Not something one remembers closely.
