hey bros, thanks for promoting my skimmer. No more monster tangs at the moment cuz my 7" Naso passed away. However, i still house about 9 tangs and 27 fishes in total.
Still wish to lay my hands on the deltec 851!
btw this skimmer is both in sump & out sump, but i feel the performance is better in sump. There's no such thing as overkill , only underkill.
