Lack of growth from acros.

IMO
There are 2 poosible issues.
1st- two AIs on a 90 is a bit under lit. 2 AIs (w/70 degree optics) would not adequately cover my 75g until I added T5s. I still had SPS placement challenges to say the least.

2nd- I did not see any feeding regiments for your acros. If nutrients are to low and not feeding, the corals definitely will not grow well bc they do not have any energy needed for growth.

I'm no acro expert but if the bases are encrusting you are getting growth. I believe they encrust first to give themselves a base then grow up.

It sounds like your system is fine...only other thing I can think that would be wrong is chemical warfare in the tank, but you say you have PE and encrusting, basically means they are healthy.

This may sounds strange, but if you are only dosing two part, maybe try dosing kalk as well or in place of to keep params? I know for some the kalk just helps with calcium based growth, I really couldn't tell you why tho.

I think fragging is a wonderful idea if they are healthy. Maybe try fragging some by laying them on their sides to spur more growth upwards. I do predict that you will be getting better growth this year tho regardless...

I had a similar situation only got my acros to grow bases and no branching at all. I ran biopellets and always tried not to overfeed and my tank was just to clean. I started setting up a new tank and while I was involved in that I kind of neglected the old tank and because I didn't change water as much and still fed everything I started noticeing more growth. On my first setup I had an algae outbreak and hated my tank. On my second tank it was algae free but had little growth on my sps. So on this new one I am trying to find a middle ground where everything seems happy.

Wrasses don't eat aefw or redbugs. At least not the ones we get. They eat another type of flatworms. It doesn't take much led light to grow sps. 300-350 led par is more like 450-500 mh par. I've noticed with my diy leds I seem to get better growth not turning my blues 100%
