SPS bleaching, and some shedding tissue

[claymc]

I've recently noticed receeding tissue on my acros and my caps are starting to bleach out, or at least loose their pop..

Suggestions on where I should start.

I use Tunze 7008 salt. 72 gall bow, change 5gal every 2 weeks. Dose 1 shot of b-ionic every other day, and have started dosing crystal MG.

I did get a nice bloom/outbreak of halimeda which, I quickly removed as it was growing 2 or 3 petals over night, I figured that was robbing my CA.

Also noticed my caps in recent growth are drooping down with heavy white rims.

thanks for any help!

Stop wasting money on that salt ;)

What is crystal MG?

How old are your light bulbs? I don't think it is the problem, but you might want to change 10 gal every 2 weeks. What are your water parameters at?
