I need some Help - Little to no growth

[Nebthet]

I had some of the same issues you are having when it came to gettin Acros to grow. I had a couple frags in my tank for almost a year that didnt grow until I started dosing.
There are four things I dose to my tank on a weekly basis.
- Kent Tech-M Magnesium
- Kent Tech-A&B Calcium and Alkalinity
- Kent Coral Accel

Within a few weeks of dosing and stabilization occured I noticed my acros were growing and have done so since. The Digis and MontiCaps which grew either way really took off at that time.

As suggested before, definately get a magnesium test done and see if it is low and raise it to around 1200 or so. 1500 if you have algae issues.
