Water flow for 55g

jmorgret · #1 07/14/2007, 01:43 PM

I want to replace my MJ1200s in my tank and was thinking of going with the Koralias. I was going to get 2 of the model 2s, the 600 gph ones, but the difference in price for the 3s in not much, so I was thinking 2 of the model 3s at 850gph. Would these 2 be too much flow for my 55g? I don't want everything blown around, but the MJs just are not cutting it and I have dead spots. Opinions?

I would get the 3 or 4 model. The flow is much wider spaced out so the 850gph may seem like a lot but it's really not. Here's a chart by Tunze which shows their water spaces and the Koralias will pretty much have the same effect:

deffinatly the 3's if you are getting just 2, i am running two 2s one 3 and two aquaclear 50s in my 65 (36") and love the flow it creates.

Yeah I would go with 2 model 3's. I used to run 2 Seio 820's in my 55g. I have the 4's in my 125 now and love them.
