You'll figure it out, these things take time.Whenever my monti takes hits like that, his polyps close and he whitens out. He likes the slow consistent flow and big thrashes smashing his polyps every 10 seconds which is what I used to have on else mode but something happened with their positioning, not sure.
These two on master slave used to create perfect waves. the water in my tank would go up and down about an inch or two back and forth. Now it's all jittery if that makes sense.
There is also some weird like sandbed ground swell that circles around and makes some of the lower lps get a little too much flow.
I feel like I'm going nut here!
Sorry for the spam again :/ all of this is very helpful.
