Enough flow???

Is 2 Koralia 4s and 1 Koralia 1 plus a Mag 12 pump creating enough flow in my 120 gallon tank? The 2 Koralia 4s are in each rear corner pointed at a 45 degree angle towards the middle. The return comes out in 2 directions towards each side of the tank and then the Koralia 1 is just in the middle.

Just wanted to check......

 

Depends on what you want to keep.

 

I am always on the side of high flow, it helps aleviate algae problems. I have two number 4 koralia, my main sump pump(about 1600 gph) and a refugium return (a rio 1200 turned down alittle). This all in a 75 gallon. I have kicked my algae problem(for now) and my corals love the flow. The way you can tell what kind of flow you really have going on add phytofeast or similar green food and see how long it takes for the water to all be green.

 

add a vortech

 

I am running with my return about 2600GPH in a 75g tank. My inhabitants are pretty much happy, except for those without a swim bladder. They are still adapting.

 

You have me outdone I think. I have two Koralia-3s, a Rio 2100 on full from the sump, a MaxiJet1200 pointed along the back glass and a Aqua C-50 on the opposite side to match my sump return flow. So, I have five sources of flow in my main tank. I have a 75g as well.

 

I have a hydor korralia 1 and a nano (640gph) in tank and two 100 gph powerheads for return with hydor flo deflector in a rsm. 840 gph total

 

I run a vortech about 1/3 power (1100 gph), 2 tunze nanostream 6045's (1189gph each), a nanostream 6025 (660 gph) and my return (425gph) in my 90. 4563gph total

 

No flo problem there

 

lol...still got 1900 gph to go if need be. I start undertowing the sand if i turn it up more than half way and the vortechs a foot up the tank
