sps and flow

[Ram3500]

I have been thinking a lot lately about optimal flow for sps . I am mainly focusing on sps corals in my reef now. I know that the more is better, its now the amount of flow that is concerning me its the amount of time.

I am really interested to hear from those who have full grown out sps tanks and what you have done for flow time ? I am currently running two wp40 on random flow from 10am to 10 pm and a tunze nano wave box from 4pm to 10:30 pm on my 150 gallon.

I recently spoke with a Can reef member who has one of the nicest sps tanks I have ever seen . I was very surprised to find out that he runs his wave makes 24/7. I have always been under the assumption that the inhabitants need a break at night but am I wrong? I tried running my pumps at night for a few week but than I stopped. The fish seemed fine they just tucked away in the rocks but my one lps a bubble coral never looked to happy.

So do I go full throttle at night ? Do I run one pump on low high I don't know
