Re: [APD] pearling after water changes Vol 2

That could work if the inhibitors where organic compounds, or more generally, the sticky types that activated carbon adsorbs. But it could control for one more of the factors that could be involved, i.e., carbon-sticky inhibitors if there are such things. No one has idientified any potential inhibitors nor their properties, have they?

Or just add activated carbon to the filter and see if pearling get
more intense?
