sps question

[El Diablo]

I have had a few sps bleach very slowly from the base up. What could be the problem. All of my parameters seem to be fine and stable.

Check for AEFW.

I will tonight that is freeky.

Mine just looks simply like it is bleaching from the base which is strange.

I had this problem with my Green Poci once, I just fragged it up to save what was left and the frags have grown nicely. Not sure what caused it in my case either, none of my other corals were effected.

or a flow issue

Did you change any GFO recently?

i have the same problem and i think it may be the lighting? have you changed yours? My 250 MH went out and i had a 175 back up but it is not near as good.
