I ordered 2 of the model 3 pumps yesterday for my 46g bowfront. I too will post pics when they come. According to FedEx they should be here on Tuesday
I am running two seio's right now in this tank a 600 and the 800 model... The tank is mostly SPS dominant as well. I like the flow the seio's put out but they are very bulky looking. The hydor's have a sleeker look to them and I like that. Eventually I will be upgrading to a 90 so these plus two more will be in that tank....

I agree with you that they could probably make it slightly smaller, but the Tunzes will hold the medal for compactness just because Hydor's mechanism for ensuring the prop spins in the right direction depends on an inch of sliding space for the prop/impeller. Also, the mounting mechanism is slightly less compact than the Tunze nanos.
Overall, this is a very great time for reefkeepers in general and the Hydors are an awesome addition to those wanting an affordable and safe way of entering the high flow, low velocity reefkeeping era that is a little bit more aesthetically pleasing than Seios.
Also, I'm not comparing these to DIY projects such as maximods and you can't mention the oceanflo mods because they are no longer in business.I mean, it's hard to think of a cheaper way of adding quality flow to a small tank. Also, if you were going add flow to a 300 gallon tank and wanted about 30X turnover. It'd be hard to beat the Hydor 4's. For roughly 400 bucks and some change, you can get 9600 gph of flow, that's probably the cheapest way of getting that much flow in a powerhead that is easily mountable and secure that is reliable (I hope...
). Of course if I had a 300 gallon tank, I might use much more expensive ways of producing flow (Tunze streams, Vortechs, Wavebox, Surge boxes with motorized ball valves, etc.), but I would still consider using the Hydors for trouble areas where I felt there were dead spots.

. This morning when I turned my tank on the water was much clearer.Beenalongtime79

spankey...
So mounting them to the surface is not a huge problem... I'd say you can mount them about 1.5", maybe 1" from the surface without vortexing (lots and lots surface are from the inlet grids), however as I stated before, these give out extremely wide and dispersed flow so the problem you run into is a lot of water movement at the surface (almost violent if you mount it that close to the top surface).

John,
OK thanks for the info. I have to mount my seio's at least 4 inches below the surface or I get a sucking vortex into the front of the pump and thus, bubbles everywhere.... Although I don't want violent surface agitation, it makes me feel better that I can at least mount them at least 2 inches from the top possibly vs the seio's....
Can't wait to get them..

If I get a couple of these for my 29g it sounds like I'll be going with the #2 @ 600gph. Also, I have my MJ900's mounted in the top right/left corners of my tank (as close to the surface as they can go) in the rear with flow directed at a 45 degree abngle down towards the front of the tank in an "X" pattern...would i be able to do this with the Koralia's?

How many and what size for a 55gal. I was thinking 2 of the #4 so if i upgrade tanks it will still work. Or will 2 #4 be to much

muleball,
You might be able to get away with two of the 4s if you alternate them on and off on opposite sides of the tank.
If you have both of them on at a time, your tank's inhabitants probably won't be so happy unless it is completely SPS dominated and even then, it may be a little too much in those zones where flows collide.
Peace,
John H.

what about two of the #2's in a 29g...would that be too much (I don't have a wavemaker setup so they would be always on)?

I'm going to go with 2 Koralia 3's for my new 75 gallon, or do you think I should go with the 4's? I'm scared that I will have too much flow.
Beaker77, what bulbs are you using in your Tek5 light? I really like the color?

I'm happy with 2 Koralia Model 4's on my 72g. I have mostly LPS and zoanthids. The only SPS I have at the moment is a Superman monti and a green monti.
Bulbs I have:
