4R00P3R Posted May 22, 2008 Share Posted May 22, 2008 I have heard so many opinions about circulation. Answer the polls and give your 2 cents. I have a mag12 for "turnover", and 3 koralia 4s and a maxijet 12 for flow in my 105g. I'm having a problem with the koralias. The fools designed it with a circular suction cup and magnet so it turns with gravity when I try to position it with the pump angled at all sideways. I get home always to find it pointing down. Has anyone else had this problem? Is there a simple and inexpensive solution? Link to comment Share on other sites More sharing options...
offroadodge Posted May 23, 2008 Share Posted May 23, 2008 I have 2 of the koralivias and they hvnt ever moved. but, if its sliding just razorblade teh glass on the inside and put it back in place. Link to comment Share on other sites More sharing options...
jsr Posted May 23, 2008 Share Posted May 23, 2008 Welcome back. I have two K4's and dont have any issues with them changing position. Does the ball socket seem to be stripped out and loose? Link to comment Share on other sites More sharing options...
Entropy Posted May 23, 2008 Share Posted May 23, 2008 I have four K4's and they don't move unless I mess with the cord. As for this poll, I think it depends on what you are keeping but for the average reef I think you should push as much water through your sump as your skimmer can process, unless you are using the return pump for your flow in the tank. For circulation in the tank (non filtering) I think you should have as much as you can get. I wouldn't add a pump just to add it, but if you have any dead spots adding more circulation can only help and I think you have to keep the pumps in scale with your tank. Adding 4 Koralia 4's to a 29g for instance would fit fine, but would probably just create a whirlpool. In my 135g I have a Rio2100 for the return pump (roughly 300 gph return), and four Koralia 4's for in tank circulation. I actually have 5 of the K4's, I just haven't figured out how to squeeze the fifth one in there yet. I am guessing I have about 30x turnover in the tank, maybe 35x depending on what flow numbers you believe for the Koralias. Link to comment Share on other sites More sharing options...
Headless_donkey Posted May 26, 2008 Share Posted May 26, 2008 dont' use your return pump has the main source of circulation. Lower flow rate through the sump will give your skimmer/fuge, other reactors more dwell time and you will have more success. I have 2 Koralia4s and love them.

GKarshens Posted May 26, 2008 Share Posted May 26, 2008 Agree with James on not using your return. I recently jumped off the Koralia bandwagon. No real problems I just didn't like their flow pattern or their lack of aim ability like I would like. I got a couple maxi-jet mods that I am pretty happy with. They move a ton of water at a low watt usage with a more wide angle flow pattern. Link to comment Share on other sites More sharing options...
4R00P3R Posted May 29, 2008 Author Share Posted May 29, 2008 I have tried cleaning the glass under the suction cups, but havent tried cleaning the suction cups themselves. The ball joints are tight; it's the suction cups that are moving. I'm not sure what to use to clean them exactly. Possibly rubbing alcohol or something?
