id have to agree , ive spilled skimmer cups , full ats mats and all inds of junk i didnt mean to and never had the ill effects yur describing.

i can almost bet its the lack of oxygen when the sheet is cleaned that the mature algae gives off that is causing you grief.

have you posted this on algaescrubber.net??

i bet you would get the answer you need off that forumn

good luck
