need advice on flow for SPS

my sump return pump is a genx pcx 40 (which is very very loud...) rated at 1190 GPH, with a 5ft head and a few other variables, im getting about 650 GPH back into my DT, which is 90 gallons, and i also have an old maxijet 1200, which is about 300 GPH give or take (thats what google said)

its a mixed reef tank, my fish never move unless its feeding time, i dont need to secure any pumps for feeding time, and i just dont think theres enough water movement, but new pumps are insaine expencive, and dont want to buy somthing if i dont need it.


so is this enough water movment, and if not my budget is about 250 for a new pump/pumps, what do you suggest? thank you all!

I suggest getting a nice submersible powerhead ,if you have one on each side of the tank creating a current that should be good enough

 

any other ideas?

 

A pair of Koralia 1050s would be well within your budget. Those along with your return flow will give you a nice 30x turnover.

good call with teh koralia brand, read some reviews and the price was right so i went ahead and got a koralia magnum 6, it'll be here on wednesday, is this enuff flow for my sps corals or should i get 2? and where should i put it in the tank? all my corals on on the right side of tank and my fancy rock scape is on the left. so same side or oposite the corals? pointed up, down stiaght?>

 

A koralia 5 is a really big pump. they are way over powered for what they are supposed to be... Actually as powerful as a koralia 7:

Also, turbulent flow is needed. in my two sps tanks i have multiple vortechs in each, my flow is 88x turnover in a 93g and 104x turnover in a 50g.

 

"A koralia 5 is a really big pump. they are way over powered for what they are supposed to be... Actually as powerful as a koralia 7:"

is that a good or bad thing?

i looked at the charts on the article (ill read it when i get to work haha) but i got the magnum 6, and its right on the money for 2200 gph, plus my return pump i should be right around 30x turn over
