I've been struck by the number of threads lately where posters with an unexpectedly low CYA number are advised that they may have CYA eating bacteria in their pools. I thought that was a fairly rare occurrence, seen mainly after months of overwintering the pool. Are we really seeing multiple instances of this happening now, over the course of just a few days, in the middle of the summer swim season?
Or is it more of an advice 'fad' at the moment here on the forum? I have the feeling I'm coming across this type of advice half a dozen times a day now, but the pool owners rarely (if ever?) come back with a report that actually confirms the huge chlorine demand that would be characteristic.
Has anyone tried keeping track to see if confirmed cases of rapid CYA consumption are actually on the rise?
It seems to me that CYA eating bacteria were a rarely seen 'zebra' in the pool problem bestiary; now they are trotted out so often as to appear commonplace.
