AquaC. Great skimmer very few problems. If water changes n gets too high it quits skimming tho. Bought it off Craigslist. Came with another tank set up.
I chose an SWC Extreme Cone Mini S, for built quality, performance and price. Overall I've been very happy with the skimmer. The only real complaint would be that it's not a true seamless cone, there's a small transition where the cone meets the neck. However, the skimmer works fantastic and I've been happy with the results.
