Some SPS are turning white

[Hentz]

Hey guys, so my tank was doing AMAZING, even when I had cyano.
Though due to the cyano, it started getting on the tips of a few corals here in there. I went ahead and tossed in some chemiclean and I've been having problems ever since..

Cyano is gone, thats a good sign. Though some of my corals are turning white such as my purple tip acro and my red planet.

Before I did a huge water change, my tank was blooming with a bacteria. Fixed it shortly after the water change, then threw in a brand new bag of chemi pure elite. Spotless, tank was amazing and great for a few days. Now its back to a slightly cloudiness and each day 2 types of corals get whiter and whiter. They still have PE.

Tank params are:
Ca: 425 (dosed some so not sure on the exact measurement)
Alk: 8
Mag: 1440
Nitrate: 0
Nitrite 0
Ammonia: 0
Phosphate: .25

Sound like my tank some weeks ago. Got tired of siphoning cyano every other day and tried chemiclean. Following the instructions to the letter, the chemiclean took care of the cyano, but also killed 13 acro colonies. The fish all survived except for one bannerfish. None of the LPS were happy for a couple of weeks and many water changes, but they too survived. When I look at all the empty spaces where my SPS used to be, I think maybe the cyano wasn't so bad after all.

Water change, use an air stone?

From the makers of Chemi-pure. ChemiClean 2g treats up to 300 gallons. It helps clean stains from red, black, blue-green, and methane (bubble) producing cyanobacteria in marine aquariums. It is completely safe for all fish, corals, invertebrates, and nitrifying bacteria in reef systems. It's simple, quick and easy to use. Chemiclean works within 48 hours oxidizing trapped organic sludge and promotes an ideal enzyme balance. ChemiClean will clean stains from red cyanobacteria in aquariums. Aquarium oxygen levels MUST be increased using heavy aeration or large air stone. Turn off UV sterilizer, ozonizer, and remove Chemi-pure, or carbon during treatment. Continue using protein skimmer, although skimmer may require adjustment to prevent excessive overflow. Maintain normal water flow using pumps and power heads. For every ten (10) gallons of aquarium water, dissolve one level scoop (included) of ChemiClean into one cup of water removed from the aquarium. Pour solution with dissolved ChemiClean back into aquarium, dispersing evenly. Successful treatment may take up to 48 hours. After the 48 hour treatment period, perform a 20% water change. Turn on UV ste

Literally, did everything you just listed lol.
Minus the air stone.

@Madrid Dan - I completely agree.. Now I'm wishing I would've just dealt with it lol. My corals had exploding color and growth. Now they look..... Kinda dull.

Weird, this morning I come home and the bacteria bloom is gone.
