I have an unknown something on some of my rocks and sand. Thought it was cyno so I ran chemiclean. Waited the 48 hours and did a 20% water change. Had the water mixing over night. As soon as I started adding the water back into my tank, my sps started bleaching out.
I thought it might be a bad batch of salt, so working with my LFS we ran a little experiment. Took a 10 gallon tank, filled it with 5 gallons of water from my tank. Added a couple little frags (including a little sps). Waited a day for all of the polyps to come out (only took a couple hours). Today, I added 5 new gallons of freshly made salt water with the suspect bag. After a couple of hours, the polyps are fully extended and looking good.
When I took the 5 gallons out of my tank, I replaced it with 5 gallons of freshly made saltwater with a new bag of salt. As soon as I added it, my other sps which were looking okay also started to bleach. Forget the zoa's they are completely closed up and my LPS (hammers and frog spawn) are barely out when they used to be huge.
Here are the parameters of my tank tested today:
Mg = 1600
KH 3.0 Meq/L 8.4 dKH
Ca = 450
PO4 = 0.03
pH = 8.2
Ammonia = 0 ppm
Nitrite = 0 ppm
Nitrate = 5.0 ppm
What in the world is going on and causing my tank to crash? All of the fish are fine and eating.
