Thanks for the pics and info mbbuna!
So what the deflector does is basically direct the flow into a narrower stream right?
siwelk I think I'm still gonna go for the pair of K3's and if the flow is too strong I'll just replace one of them for a weaker model and put the other one in my 30g planted FW tank or use it as a salt mixer.
I don't know what type of corals I'm gonna keep yet. I haven't done too much reading on corals yet. Right now it's a FO tank. I'm getting some free LR tomorrow so I'll have a FOWLR in about a month after it's cured.
