2 Koralia 3's (combined 1700gph) in a 46g?

[Doobze]

Exactly as the title says, is this too much flow in a 46g? Right now it's fish only, sort of. I have a red mushroom colony that hitchiked on the rocks sitting at the bottom. I'm sort of concerned that the current is too strong for my 2 green chromis, cleaner shrimp, and ocellaris in there right now for them to be comfortable.


Opinions?

40x flow would be 1840. You should be fine.

Your good.Mess with the heads a little to adjust to a comfortable current for the fishies

i previously had a 46 bow with two Koralias #3 and quietone 3000 for the return and it was fine.

I'm at least 1300gph in my 40 breeder and Im going to add a koralia 1 just for a few
weak areas that I don't care for.

Alright, good to know. It just seemed that my fish seemed to want to hide a lot more once I plugged the second one in. Then they all came out to play as soon as I took it away haha.

Then you have the flow direction I. The wrong area. Try turning one of the koralias ro a wall and let it bounce off.

Try lots of directions. I played with mine for over a 2 week period before I was happy with my corals iverts sand and fish.

i have a 46 and i have 2 k3 and 2 k4 so yea ur fine.

IMO it'll be hard to adjust them for the right flow. I have a 40B which is actually 50 gal and I run two K2 and one K3 and I have a hard time because the K3 pushes soo much. I did have three k 2s and it was just about right.

there great pumps mine have been going for 2 years no problems

DOTZ -

I have a 40 breeder and honestly never realized it is a 50 gallon tank.

Why are they called a 40 then?

That's cool - you made my day, I have a bigger tank then I realized!

[Doobze]

Yeah, I'm running into the problem where if I point them downward at all they start to move the sand around. I'm thinking of running 2 K2's instead.
