KMiller Posted May 23, 2010 Share Posted May 23, 2010 I have 2 Koralia 3's in my 46 bowfront and I was wondering, do you all that that's too much flow? I was gone for the weekend and just came home today to see that hubby turned off the 3's and put in a Koralia 2 and everything seems much more open and happy today... so that's why I ask! Should I get a couple smaller ones and not use the 3's? Quote Link to comment Share on other sites More sharing options...
reefnjunkie Posted May 23, 2010 Share Posted May 23, 2010 I would not have said that was tomuch at all-you may try what he changed it to, and then switch it back see if things go back to being less open. My 75 gallon is 4 feet long and I have an MP20 on each side pointing at each other-they are on reef crest mode which has them pushing between 350-1400 GPH each on the % I have them (about 70% of max), and my corals are VERY happy On full power (100% since you can adjust them) they push 2000 GPH each, plus my return ios pushing about 1200 GPH- So in comparison-you are not pushing to much water- Quote Link to comment Share on other sites More sharing options...
ReeFit Posted May 23, 2010 Share Posted May 23, 2010 It all depends on what your growing in there. I have my mixed tank setup so there is a slow area and a really fast area that way the mushrooms can come out and photo. Quote Link to comment Share on other sites More sharing options...
ReeFit Posted May 23, 2010 Share Posted May 23, 2010 i guess i should example my setup: 55 gallon tank, mostly soft corals, leathers, mixed LPS, minimal SPS 1200 circulation 2200 koralia 800 auqueon 250 auqueon Quote Link to comment Share on other sites More sharing options...
KMiller Posted May 23, 2010 Author Share Posted May 23, 2010 I have a pretty similar set up coral wise. With the 3's i have 2800gph flow all together. Quote Link to comment Share on other sites More sharing options...
newfisher Posted May 24, 2010 Share Posted May 24, 2010 I wish there was the perfect reciepe for a specific tank,but there isn't. Experimenting with different powerheads is a great idea. Watch the change over a couple days,especially when you feed so you can watch the flow patterns and make adjustments as needed. Quote Link to comment Share on other sites More sharing options...

It will need to be minor adjustment and then wait. Making to many adjustments to soon can just be a waste of time. Quote Link to comment Share on other sites More sharing options...
impur Posted May 25, 2010 Share Posted May 25, 2010 I have about 4500gph in my 75gal. You've got a long ways to go!! (laugh) Quote Link to comment Share on other sites More sharing options...
andy Posted May 25, 2010 Share Posted May 25, 2010 IME, the smaller the tank (particularly the shorter the tank top-to-bottom), the tougher it is to get decent flow -- especially for a mixed reef. There's just not enough room in there to get the strong random flow SPS want without simultaneous blasting LPS to oblivion. I'm facing the same issue in my 55gal. Too many or too powerful Koralias peel my acans and frogspawn, too few and I get unhappy SPS :-( I think the best solution is a controllable pump like a Vortech or Tunze... their surge/reefcreft modes do the trick without blasting. I used to have 3x Tunze 6055s with a Neptune AquaSurf in my tank, and they were GREAT... regret selling them every single day. Quote Link to comment Share on other sites More sharing options...
