help with 90 SPS set up

[rduong89]

Well i just upgraded my 20 gallon to my 90. I want to do sps this time and would like to know how much more flow i would need? Right now all i have is 2 koralia 4s running in there wil softies from my 20 gallon. Im planning to add a magdrive 1800 as a return pump and have a scwd. Is that enough flow?
Here is a pic...

try putting the koralias at opposite ends of the tank and point them directly at each other. It might help create a more random, turbulent flow from the collision of the two streams. Experiment and see what gives you the best flow throughout the tank.

That was to much flow for the other tank and about the minimum for this one. . With such a large upgrade then i would think you would have some type of cycle and testing is the only way to tell.
SPS like more mature tanks and constante steady controlled water readings. You could spend over a thousand buck on stoneys to only loose them 1 yr later. Many mistakes take time to show and can be expensive.
