Well this summer has been quite a battle. We've had unsually hot weather and it's been hard to keep my tanks temp in check (ya I shoulda bought a chiller) and since the heat I've been having some issues. I lost a couple of sps
to totall bleaching but my other sps
have alll dulled. I have 3 montipora's and the polyps went from bright green, orange and purple to all dull colors. All my other acro's have all gone dull as well. Can this happen from the heat?
Nitrate - 0
Phos - 0
Cal - 420
are totally fine, only my sps
seem effected. I'm running 240 watts of LEDs over my 55. I've got them turned down to 50% which is where everything seemed happy until the summer got hot. I also started a new bucket of Instant Ocean salt around the same time, could I have a bad bucket of salt?
