water flow with wav

[gandolf8]

I have an 180 gal clown fish Harem tank w/50 clownfish and 15 anemones.
I have 2 wav 1 at ea end. I am running them at 21% . Should this be higher or lower or should I keep them at 21%. thx.

It really depends on the type(s) of anemones and your rock structure. Posting a video that shows the flow will help.
