So I bought a Koralia #1 for my 28 gal. I already had a maxi jet. I have to say that I like the Koralia so much better, it's just the coolest pump I've ever seen. I do however, have a doubt that it's truly 400gph? Maybe it's just because it seems like the flow disperses over a wide area compared to the MJ?
Anyone else have any thoughts on this?
One, I do agree that although the flow is very strong when your fingers are right up against the head it does seem weaker as you move them away because of yes the dispersed flow. A much better path of flow plus you aren't having a 1200 jet shooting at fragile coral tissue. Secondly, I've read (Subliminal or ClownLover maybe?) that they regretted the #1s and recommended the #2s. They also have a nano sized one now that I've heard good things about.

I love the nano. I got one of those the other day to roll the chaeto in my fuge.

Thanks, I think it is working ok, especially for my little tank. But now that I'm finally starting to get my first little tank set up well I find myself wanting a bigger and better tank ;)

twasn't me Grins.. I've had my #3's from the beginning.. I also question the gph but with the changing my MJ over to the modded I now think that it might be closer than I originally thought.. I am also personally changing my philosphy about how many heads in my tank and will probably be downsizing to the #2's and placing more of them to achieve a more chaotic flow structure..
I'm hoping that Hydor finally comes out with a controller to work with these other wise I'm going to end up going with the Seio..

I have a #1 in my 30 gallon and I too questioned the gph. It is a nice pump; I like how you can change it's direction so easily. Had I seen it in action before I purchased it I might have gone for the #2.

I did the same as Vorix...got the nano to roll the macroalgae in my fuge. Not sure what else I would use it for. I have 2-4's and 1-3 in my main tank and love them all!

I wouldn't mind a couple nano's to put on the back of my tank. They are pretty close in price range to the 1200's. I need more power outlets!

I'm thinking about getting a nano for the back left side corner of my tank as well. Have it towards the bottom pointing up

Let me know if you decide to do it. I am curious how well it works. I guess I could easily test it with my current nano but I hate robbing peter to pay paul!
Or...you could test it and let me know if I should buy one. :grinyes:

Dumb question alert.
Which are better, the 3's or the 4's? Any noise/size issues, etc?
Thinking of getting a couple for my 75, yet another example of breaking my own rule about buying everything twice due to inadequate research.
I have (2) #3s in my 55g, I'd go with the #4s in a 75. No noise issues and my dealings with the manufacturer couldn't be better.

HAH! IF I do that and it goes well then I will end up paying way to much at my LFG for 2 extra nanos! If I do it before you I will let you know! I got my 2nd overflow in earlier so I will be setting that up tonight. Doubling my return should do me some justice. I might even have enough flow in the sump/refug to still the nano!

I have 2 4's. 1 on each end. The only problem I have is aligning them just pefect and not messing up the sand bed. There is no noise/size issues with the 4's at all (granted they are rather large). I have almost convinced myself I should have gone with 2 3's so that it would be easier to control. Either way you are going to be happy.

I'm thinking of getting two #2s and using the #1 on the bottom pointing up. Do you think this would be too much flow for a 28g?
Just a FYI :
I got a nano, and while they put out less then the #1 they are great. But they don't have the aiming ability as the #1's, since they use a much cheaper type of joint on the nanos..
But it is great for sticking in small places.. And it's a little more directional then the others in the line.. I'd a good purchase if you can find one for a good price..
