Never could get a solid number, consistent reading but phos .7ish and nitrate was 50ish and this could have been going on for weeks. I started to change water and had to leave town for 5 days with tank unattended. Caused all sorts of unwanted algae growth. Attempted to prune back most but I have a few chunks I am still trying to baby back. Oregon Tort is a beast I tell you, like not fazed one bit by this! Rest was a lost cause, l consider myself pretty lucky all and all. My SPS was not where I spend the bulk of my fun money on lol and will be pretty easy to replace, just a kick from behind watching all your hard work in growth gone. Lesson learned, really got fortunate.
