testing parameters/categories

[GQ22]

Something is not right with my tank, all my lps are shriveling up or stressed.

i tested for ph, gravity, ca, alk, and all are fine. i dont believe i have phosphates as my sps are still doing fine. Is there some other category i should be testing for?

ps i dont really feed my tank. skip days and only feed a little bit. can my coral stress be from a lack of feeding?

im all caught up in the low nutrients.

can something be leaching toxin in the water? do u use carbon?
or lighting too strong?

What kind of lighting? How much flow? And which LPS and how are they behaving that they look stressed?

i think i found the problem....its my bulbs, they are at the end of their one year life..if not past...been using ushio 10000k....all my sps are dyning now...only thing still going strong is the zoos...but maybe they will even face, order aqualine buschke...damn it...should have done a better job keeping track...prior to this, i even managed to color up a browned out coral to baby blue...hopefully my bulbs come in time...this sucks...
