I run a aquaticlife 115 mini skimmer in my 10 gal whatever tank and can't complain about it for the price. I also run a tunze 9002 in my biocube 29G and so far I am not really impressed with it. Trying to find that sweet spot. I know many think nano skimmers are a waste, but seeing what they do pull out is proof enough to me. I plan on adding a reguim to my biocube and when I do that will get a better skimmer.
SCA-302. After we got the second one that wasn't cracked, it's doing a great job. Reasonably priced and the company stands behind their product. I will say though that if you are new to the hobby, the "instructions" are not user-friendly. If we didn't already know how one of these went together, I don't know that we would have figured it out by the poor instruction manual.
I just switched out my Bubble Master 250 ( which was pretty decent ) for a Reef Octopus 5000 int which is pretty awesome, on my 233.
I need to empty the skimmer cup every 4-5 days or it really starts stinking up the house.
