Pledge and SPS Corals?

[aaron23]

Hi Randy,
My GF sprayed pledge last night and I'm wondering if that is the cause for one of my maricultured colonies to RTN.

She used the pledge on a table about 10 ft away and the apartment is very small..(NYC apartment is 350 sq ft studio)

Here's the ingredient list on the pledge taken from their website:
Ingredients

It's hard to tell, but a lot of those would have soap/surfactant like effects and might have impacted a coral if it got into the water (and it could, through a skimmer air inlet or the tank top).

GAC would be useful, as would skimming.

Doing those two and also water changes. Thank you Randy!
