    I'm setting up a small breeding and grow out rack and would like some advice/thoughts on using a fluval 406 as the return pump. The rack will be 4x 20 longs above with a 40 breeder sump. The 406 will sit just below the 40B - so water will siphon into it. The 20 longs will be above the canister...

    I've got a Fluval 406 that feeds water into a 28" long, 2" diameter Griggs style CO2 reactor. I currently run my CO2 at ~6 bps.

    How well does the U4 work as an internal filter? It would be an additional filter for me, sorta like a powerhead per say. Since I'll have a Fluval 406 it might not be enough flow around the whole tank.

    I'm in need of a new canister filter as my Eheim Ecco 2236 cracked on me and it wasn't properly rated. But now its turning into the holiday season so there must be some good deals coming out. I teared down my tank and now I've rebuilt it and am using sand instead of gravel. Do you think a...
