For my 55g fowlr, I am using a closed loop system pumping around 800to 1000gph...or so.

Need to add 2 circulation pumps , thinking of 2 koralias.

Should they be Koralia-3 or koralia-2?

Pls advice whats best setup for circulation !

I would suggest the koralia 3. I had one and it wasn't too strong.

I would go with the 3 also. I have a 55 with a 4 and a 1. The 4 is almost to strong and the 1 is low flow. They work perfect for my system.

I have model 2 in my 55 and it is not enough. Going to purchase model 3 to use in addition to

Kor 3's

3's for sure. I have one 2 & one 3 in my 55g and find the 2 pretty weak. It'll be replaced with a 3 shortly.

I would say atleast the k3 or even better a k4. I have been running 4xk4's on my 90gal (SPS dominante) and it is still not any "hurricane" force flow.
