Hydor Koralia 1

they are currently recalling some batches of number 2 and number 3. I would wait until that settles out. The number 1 and number 4 are still ok.

 

As I'm looking at my 2...what's wrong with them?

 

It seems that in a few batches, the motor wasn't sealed properly and you could potentially get a shock. The problem is, they don't know how many different batches are affected. As a result, they are having distributors ship all of them back because they need to figure out which batches are bad.

 

yeah, I read that too.. 2 days AFTER I ordered my 1 lol.. glad it didnt affect mine

 

Any updates on people using these powerheads in their tanks? I just ordered two K1s for my 46 gallons. I hope this is going to be enough flow. They are going to be replacing my two MaxiJet 900s. 400GPH(Hydrolia) versus 230GPH (MaxiJet), the K1s better be enough!

 

I dont think thats going to be enough for a 46gal personally.
I only have a 29gal and it moves water, it just doesnt feel like it since its so dispursed. I hhave seen the K4's in action in my friends 260gal and those things can move some water. That being said, I think I will probably get 2 K2's for each back side and put the K1 in the center facing the front glass. Or maybe just stick with 2 more K1's. This recal crap is killin me.

 

i HAVE 2 #1 IN MY TANK AND THE FLOW IS AMAZING, I WOULDN'T GO ANY HIGHER BECAUSE I FIND RIGHT NOW MY FLOW IS JUST PERFECT. IT DEPENDS ON THE CORALS YOU KEEP AND YOUR AQUASCAPE. WITH MY AQUASCAPE AND CORALS IT'S PERFECT BUT I ALSO HAVE A MAXIJET1200 AND 200GPH FROM MY FILTER.

 

cool. I will probably stay with K1s because they area readily available.
Plus my new penguin 350 should be here this week plus the flow from my aquac remora..
is the prop on your pump red or blue like the pic i posted above? I could have sworn that they were supposed to be red

 

Cool, ya... I have read that the flow is much more dispersed for the Koralia's and not a stream of water. So, since you have two K1s in your 55 and it works great, hopefully that will be good for me. I too have a Remora with a Maxi Jet and a Penguin 200... so hopefully that is enough flow.

Although, I'm working on a sump right now and was thinking of getting rid of the Penguin 200 and moving the Aqua C down to the sump. Perhaps that will decrease my flow a lot. Oh well, we'll see. In the meantime, I'm really anxious to get the K1s!!! ;D

 

Well I feel your flow should depend upon your tank. Everyone's aquascape is different as well as the corals we keep so the flow you require depends on your tank. I won't name names but I used to go on another forum and they said I didn't have enough flow when I had 2 mj1200, 1 mj400, 1 ph w/176gph, plus 300 gph from my filter. This was alot of flow. My corals were unhappy, bending over, closing up, there was a vortex in my tank. My tank is only 13inches wide so there was no need for this amount of flow especially since I wasn't housing any flow demanding creatures. Needless to say my corals are really happy, the tank is looking really good. It's all about playing with the current and finding a happy medium.
