Question on N03 and P04

iloveswfish · Aug 23, 2015

i have a question, i have zero on both N03 and P04 and i am having a probllem with my GSP i was told that the reason it is not opening is due to the lack of NO3 and P04

i need some advise as to what to do. i have had that coral for about 2 weeks and i had it at the top and it did not open i then moved it to the middle and a couple of polyps opened but now it is on the bottom and it is still not opening.

My previous tank had gsp growing wild everywhere. When I set up my 210 last year I threw a piece of gsp down on the sandbed and it's sat there for a year, opening every few days for a short while. Now it's beginning to color back up and staying open for most of the time. The only changes I've made are adding more fish and feeding more to the tank. I've noticed most of the polyps that are notorious for trying to take over a tank (gsp, anethelia, yellow, zenia) don't grow well in new setups so I assume it's from lack of nitrates and phosphates.
