Too much flow?

[TCoach]

I replaced my 4 old school AC powerheads with 2 CP-150 Gyres running at 50% in Mode C (Random, I believe). Do you think it is too much flow?

92 corner with gyres mounted vertically at the overflow shooting down each side. It’s a mixed reef, but starting to lean more towards SPS.

what do you think?

Doesn’t look like it to me, looks just about right. But if you think it’s too much turn the gyres down a little.

Looks fine to me. If a coral is getting too much flow, it usually limits polyp extension even after giving it time to adjust to flow changes. Just avoid sharp direct flow. I have the CP-150, CP120, and 2 SCP70 in my systems and love them. Might even upgrade to the CP180 later, but for now everything is happy.

agree, seems about right. Nothing being overly blown away.

I have two 4k icecap gyres running at 10%-80% depending on the schedule it's on. My tank is 75g and my two frags seem ok.
