I'm still fine tuning mine, but I think it will work. It is kicking up a little sand, and slowly shifting it. I agree, these things rock!! At first I didn't think it was putting out 2100 gph through my MJ 1200, but now I am a believer! I hope everything settles down, so far my corals have responded great and my clowns have been playing in the flow all day!! Have you tried the smaller empeller? How big is your tank? Just curious. One thing I love about them is their manuevering. With the swivel head you can make a small adjustment without moving the entire unit. _________ 55 gallon slowly growing reef aquarium, 85 lbs. live rock, 2 1/2" sandbed, 1 False Percula Clown, 1 Sixline Wrasse, Tetratec PF500 filter, 2 110 watt URI Super Actinic VHO actinics, 2 250 watt metal halides with Reef Optix 2 reflectors powered by Blue Wave 3 ballast, born 1/3/08 My Tank Thread My Tank Video |
