jimi thing Posted October 19, 2011 Share Posted October 19, 2011 I've got a Oceanic 30G cube tank and I'm getting ready to add some flow. My problem is I don't know which option to choose. Option 1) 1 Koralia 1050 pump Option 2) 2 Koralia 425 pumps I can't afford an MP10 so that's out of the question. Also, I don't want a sand storm going on in the tank. Stocking plans: Mostly softies with LPS. Thanks for any advice! Link to comment
DIstudio Posted October 19, 2011 Share Posted October 19, 2011 well I have 2 K nano's (425 version) in my ten gallon on top of an AC70...and nothing complains, in fact I still have some dead spots in the tank just food for though. Link to comment
jnelson Posted October 19, 2011 Share Posted October 19, 2011 I would say two 425s pointing at each other (one on the left and one on the right) for some random, turbulent flow. Should be more than enough for just softies and LPS. Link to comment
AZDesertRat Posted October 20, 2011 Share Posted October 20, 2011 Probably two of the 750 version would be best. I have the 425 along with an old K1 in my 16G and theer is not much movement. I have two of the 1400's in my 100G on a RKL wavemaker function and love them! Link to comment
fewskillz Posted October 20, 2011 Share Posted October 20, 2011 Koralia's put off more heat than people realize. Plus who wants that much equipment in their tank? I'd go with the single 1050. Link to comment

AZDesertRat Posted October 20, 2011 Share Posted October 20, 2011 Koralia Evolutions put off very little heat. They are extremely energy efficient and draw minimal wattage compared to many other pumps. I replaced some older K4's first with Sicce Voyager 3's then Evo 1400's. The results with a Kill A Watt meter show a big improvement with the Evo 1400 coming in at a whopping 6 watts, compared to the Evo 3 at 15 actual watts (rated at 10) and the K4 at 15-16 actual watts. Thats a huge improvement, 1400 GPH at only 6 watts. My non scientific flow test shows the Evo kicks out some water for sure. I ground up some flake food and dumped it in front of each and the Evo blows it to the opposite end of the 60" tank easily while the others were less dramatic. Compare any of the above to an old MaxiJet 1200 which produced only 292 GPH at 23 watts! Power consumption and heat gain have a direct relationship with any submerged or product cooled pump. Two smaller powerheads is always preferrable to one larger one since it gives you more random flows when they are pointed towards each other from opposite ends or sides. Link to comment

You're correct, but we're talking about a 30 gallon cube, a 1050 is going to produce crazy flow. In fact, now that I think about it, it might be too much for such a short distance. It could be impossible to keep sand in place across from the powerhead. So I'm going to modify my answer. If you're planning to be SPS heavy, then the 1050, anything else, the dual 425s will be fine. There is no right or wrong answer. Link to comment
DIstudio Posted October 20, 2011 Share Posted October 20, 2011 I agree with Skillz, two 425's would be nats ass. and I'm sure you could find some used dirt cheap. I think I paid like 10 a peice shipped for mine from the classfieds thread. I know i'll be putting mine back up soon as the 40 gets done and my elusive mp10 shows up... Link to comment
AZDesertRat Posted October 20, 2011 Share Posted October 20, 2011 The 425s are too small. I need to do a video of my Evo 425, K1 and a modified AC 500 refugium on my 16G bowfront. The leathers and sebae anemone hardly move at all and for SPS or LPS they would never work. I do like the smallness of the 425 though, its not much bigger than a gold ball in size while the 750, 1050 and 1400 all share the same body which is about the same size as the old style K1. I have photos of the K1 and 1400 side by side along with the Voyager 3 and the K1 and 1400 are very close while the Voyager is over half again larger. Two 750's would be perfect. Link to comment
jimi thing Posted October 20, 2011 Author Share Posted October 20, 2011 Thanks for all the advive given. I'm thinking 2 750's might be the answer but I just want to make sure that it won't be too much flow and kick the sand around. I had a 70g long (82"LX14"H) and had 1 K4 on ea side and had problems keeping the sand in place so I don't want to have the same problem here. Also the tank is a cube style and not sure how the two larger koralia's will look as apposed to the 425's. This is a tough decision. Thanks again for all the help, it's much appreciated.

AZDesertRat Posted October 20, 2011 Share Posted October 20, 2011 My 16G has 2 to 3" of sugar sized Southdown sand in it and the 425 and K1 don't affect it at all. The 1400's in the 100G will move sand if pointed down but the idea is to point they slightly upwards so they ripple the surface and provide oxygen transfer. Link to comment

jimi thing Posted October 25, 2011 Author Share Posted October 25, 2011 Well two good things happened today, ended up ordering the 1050 and my led's showed up in the mail. Link to comment
