New light settings new brown heavy dusting
So for over a year i fought with trying to get my zoa's to grow or even not die. My water was clear and tested great.
Then i rented a par meter to find even though my lights seem very bright to me they registered 80 on surface and 10 on SB.
So I adjusted settings to 400 top 80 SB and zao's started to pop and grow. Soon after the brown dusting began and if i dont get it every day it gets bad.
Water temp is around 85F. Is it too much light or too hot of temp causing the brown dusting growth. Or other.
Thanks
