You indicated that your water parameters are as follows:

ph=8.4
nh3/nh4=clear
no2= clear
no3=clear
alk 3.6
is this to high?
cal=400
temp=78
this is a 90gal tank
salt=1.025

I don't see any obvious problem here, assuming that the units of alkalinity are 3.6 meq/L.

Without knowing more about the test kits you are using, I don't know how to interpret the nitrate results. What concentration is "clear" supposed to correspond to?

Additionally, if you are having difficulty getting coralline algae to grow, I would suggest that you monitor phosphate in your reef tank. Excessively high phosphate will pretty much shut down coralline growth in a reef aquarium.

The hair algae issue probably has more to do with biological issues than with water quality. You need to find a critter that will eat hair algae.
