Guys my zoas specially the bambams turns pale and are always half open.
My water parameters are: (all tested using API test kits)
NO3 : 5ppm
PO4 : undetectable
Alk : 8
Ph : 8.2
CA : 420
Dont have a Mag tester.
I'm using leds, and they have been in that place ever since.
Light intensity maximum was Ch1 55 Ch2 50
And my live rocks are full of the dark maroon-like algae, dont know if its macro but its a nuisance since the zoas dont spread over them, are these Dinos? they are not slimy and has a carpet-like texture when touched.
