Q.Irish moss turned yellow
A blow up floater from the pool was laying on top of the moss for about 2 minutes and now it’s turning yellow. What can I do to stop this?
Given the timing of the moss' demise with your pool's blow up floater, I would say that chlorine from your pool water might be to blame for your irish moss turning yellow. It does not seem as though the floater would be heavy enough to damage the moss by sheer weight. The best thing I can recommend is rinsing the moss with clear water from the garden hose to flush out any possible remnants of chlorine.
