Waterflow Question

[ROBERTCHAPA]

i have a 90 gal with live sand and live rock and fish and i don't think i have enough water movement , i was thinking of getting a koralia pump but dont know what one to get or should i get 2 of them they have 1-4 models not sure how much flow i need in the tank. any advice will help

i would go with at least one koralia 4. i am planning on 2 on my 90. it really depends on what kind of corals you plan on keeping, sps needs atleast 30x turnover in your tank which would be at least 2700gph of circulation. but if you don't have corals and don't plan on it one should be fine just to get the water moving around and help with dead spots.

you should have been 20-40 times tank turn over per hour

doing the math--in a 90 that would be 1800 to 3600

I am running 2 number 4's and one number 3--thats 1200 plus 1200 plus 800--3200 gph

I run the 4's in the corners and the three pointing more at the surface
I like the combinations because of the flexibility of redirecting them
