bwhyit Posted December 7, 2009 Share Posted December 7, 2009 Here my current setup: 12g Nanocube DX Koralia nano pump ~14 lbs of live rock (covered with life- mushrooms, small anemones, etc). 10 lbs of live sand 2 red legged crabs 2 turbo snails 2 False Percula Clown fish Here's my problem. When my Koralia is on, the crabs, snails, and my Clowns don’t seem very happy. The snails and crabs stay pretty much hunkered down and don't move much. The Clowns just hang around in the top corner of the aquarium in the pump return current. As soon as I turn the Koralia off the snails and crabs come alive. The clowns also come out of the corner and look much happier. I've tried moving the Koralia around in several difference places and nothing changes. Fish, crabs, and snails are still unhappy. My question is, do I really need the Koralia nano since the stock pump already turns out 106 gph? I feel like I need the circulation but everything seems happier with less water movement. I'm thinking maybe an adjustable pump with less flow but I'm like to see what everyone else thinks. I've also thought about setting the Koralia on a timer and only running it 2-3 hours during the afternoon. Any suggestions? Thanks. Link to comment
