Acro and Meteor showe bleaching

Just looked in my tank and both of these are half bleached. What is going on here? I know my nitrates are up since I fed but since I witched to Ais I cant do good with sps. Is it time to go back to t5s? I'm about to upgrade to a 220. I run them at 40 % is all. Zoas are doing great.

 

I suppose it could be a lot of things, but if the lights are new, I'd back them down to 25% and cut the hours down to about half of what you're doing now. Could be the nitrates too though.

 

not newprob 1 yr old. Think its the temp change on adding water.

 

Check your alk and your phos levels. in my opinion those are the two most important parameters when keeping corals

 

+1

 

40%

I run mine at 80%

But yeah, the first thing I would check is nit, alk, phos.

 

My nitrates just spiked upto 40 but we were thinking because of the corals bleaching and dying off. Phosphates are ok and I havent checked alk.

 

Hey pot how high off the water are your leds? Mine are only 5 inches because they're in a canopy.

 

4"

 

Check those levels but also what additives are you adding currently?

 

Hey Pot on;y keeping them 4 inch off do you have water splash or have glass in between?
