koralia?

I have 104g tank 36x24x28
I think I need more flow since my return lines are lined up with the surface to provide more water movement at the surface and also so only a limited amount of water siphons down to the sump in case of loss of electricity.

I was thinking of 2 - Koralias#3 for the middle of the tank - not too close to the sand. I only have fish at this point, but will add an anemone in the future.
I've seen the Koralia #4 and they are big. I was wondering if the #3's are as big and only differ in the amount of water movement they provide.
Any input from Koralia users would help a lot. Thanks

Just so you have an idea, here are some pics:

I think the only difference is the size of the prop on the impeller. The housing is the same size.

I currently have 2 Koralia 4s in my 75gal, with 2 Seio 820s and a MJ1200 in my 75gal giving me roughly 4240gph. And i'm considering adding another Koralia 4.

I think you would be more happy with the 4s.

wow, that sounds like a lot. Thanks. If the size is the same, might as well go with more flow

You can also mod them to get even more flow.

The 4's are larger then the 3's.

Thanks for the correction, i have only seen the 4s but thought they were all the same size.

Petsolutions.com has the dimensions of all the koralia units.

Buy the 4's and mod them. You can cut back on the number of pumps you need.

thank you everyone. I think I'm leaning towards the 3's just because they won't be so obvious.
