2x Koralia 1's enough in a 75 gallon?

Reason I ask is, I need to buy another powerhead for my saltwater mixing barrel anyway ... so if I need more flow in the DT I'll use one of these Koralia 1's for the mixing barrel and get a bigger one for the DT.

My return pump is a Rio 2500, pushing roughly 500gph. So, 1300gph are flowing in the DT right now.

Thanks!

 

In the 75 I had I had two #3's

 

1,300 is nowhere near enough. You should have somewhere around 3,000 gph total.

 

I would also suggest 2 #3s also.

 

I have two 3's in my 72.

 

I have 2 K1's in my little 20G, that won't be anywhere near enough for a 75G. Go with what the others have suggested, get K3's. They are more expensive, but it's better than spending $80 on them and realizing you should have bought the 4's, and are forced to spend another $100, then to have the 3's just sitting there collecting dust.

 

At least throw a #4 in one corner angled out to the middle of the front glass.

 

I'm using a single #4 in a 90 and it's working out pretty well, I use a #1 in my 24g nano no way I'd suggest it in anything larger than a 30

 

i have 2 #3s and 2#1s and my return which is a rio 2100 and i think i still need more, oh yea my tank is a 72 bow

 

well, 3reef's done it again. now i'm buying 2 k4's for my 75! i'm telling my wife it's your fault...
