Mass Coral Death

Yes, I keep a log of everything.

pH is between 7 and 7.5
dkh is usually around 8
Ca has been a little higher because of the Kalk at 450ish
Mg has been around 1300-1400
nitrates up to 0.5
nitrites up to 0.25
ammonia up to 0.5 (now less than 0.25)
temp (without the a/c) hovering between 80 and 82. Have had a fan blowing on it. Just last weekend we put the a/c in so the ambient room temp has been cooler. Now around 80 consistently. Tank is 3.5 years old here but was cycled already when we got it, just moved it 4 houses down the road.

The snails that died off were the nassarius snails. I also had tons of spaghetti worms and they are pretty much gone now. Now I have lots of sponges, serpent stars and bristle worms. My astrea snails are breeding like crazy. I have a ton of babies. Tube worms are making a come back.

I use tap water, usually made up the night before, with vanquish, heated, with powerhead. h2ocean salt. Basically the same process for 3.5 years.

I will test again tomorrow when I get home from work and post exact levels.
