This is what's so frustrating about this hobby!!! Good luck buddy lots of ups and downs with sps once u get tank dialed in again and wait few months it will be back to its prime !
Just takes 1 day for whole tank to start looking like crap and months for it to recover !! One u see new encrusting growth again u should be good!!
Still have no idea. Maybe bacteria maybe alk swings,salinity? Cant figure it out. Still have some acros not totally gone but some of my favorites are. Carls candlelight,pearlberry,red planet colony. But some other favorites i still have Joe the coral,shades of fall,blue-green tort. Didnt put them in the DT i have my 10 acros in my frag tank. Going to upgrade so not going to place them in till i do
180. If everything works out i am upgrading the middle of may. If it doesnt work out going to keep my setup. All how the cards fall I know by the pics you cant see much but if you saw my tank before and after in person you would see. Got so bad i last my colony of green slimer. That guy could be left out for a week and i wouldnt die LOL
