Hello fellow acropora keepers. Tank has been up and running 1.5 years , I get little to no polyp extension and I can’t figure it out , looking for your input and what has worked for you. Some important information: reef is 225 gallon peninsula with 45 gallons in sump , filtration is via bubble king 200 Dc and clear water aquatics algae scrubber and filter socks changed every 2 days. Flow is 3 x Ecotech mp40 and 2 x wav pumps and dual return lines fed by core 20.
Lighting is 2x250 w metal halides , 1 x Ecotech radion gen 5 , 4 x 80w t5 and 2 x orphek 0r3
parameters

Po4 - 0.08- Hanna
No3 - 14.5. Hanna high reading unit

Cant figure out why little to no growth or polyp extension on these Acros. They don’t die , they just don’t do anything.
