LPS melting away

Over the past month or so, all of my LPS corals have been losing tissue and I cannot seem to find a solution to the problem. The water parameters have been stable (#s listed below), no new fish (none in the tank at all), and no visible pests. A few heads of one euphyllia appeared to be infected with brown jelly, but that's the only coral with any visible symptoms aside from recession. I've tested for heavy metals and all tests came back negative. The strangest part is that everything else is fine: zoas/softies are growing as usual, gorgonians are still extending polyps, and clams have not shown any warning signs. I'm losing my mind trying to figure this out...any ideas?

Temp: 78
Ammonia: 0 ppm
Nitrite: 0 ppm
Nitrate: 15 ppm
Salinity: 1.026
Calcium: 420 ppm
Alk: 8.4 dkh
Mag: 1600

Three things come to mind....
1 - Double check your water parameters just to make sure you don't have a bad test kit/refractometer. Oh and get the phosphate tested.
2 - Stray Voltage?
3 - Bacterial infection. Reefcentral prob has more to offer on this. I don't have any experience with this or how to treat.

Other then that I don't think running carbon would be a bad idea. Do you have any large leathers?

Thanks for your input Dave.
1. I had the guys up at Fintastic test the water a second time and they got the same results. I didn't ask to have the salinity compared; good idea. I'll check the phosphate level too.
2. I'll look into that.
3. Ok. I'll post something over there if I can't find the culprit soon.

I didn't run carbon consistently, but have had some running for a bit over two weeks now. There is a large toadstool in the tank. I suppose chemical warfare could have something to do with it.

Are you dosing mg? Seems a little high. When I was dosing mg to kill bryopsis the 1st things to suffer were my lps.

1600 is very high yes but it should affect only inverts at this range no?

Hard to say I dosed mg on 2 different occasions in a battle with bryopsis and both times my lps suffered some to the point of never coming back.

I was dosing just after stocking the tank since I picked up a few frags with bryopsis, but haven't dosed any mg in almost 2 months.

I would try to get that mg down probably have a lot of heavy metals in there.

This is just spitballing a differential diagnosis... How about checking bulbs..? Softies will adjust and so will clams to lights changing spectrum. What lighting system do you run?

The bad test kit check was my first thought but since you've double checked that we can rule it out. Mg does seem high too. Just my thoughts.
