@Byron, I know you have a more scientific outlook on things... What do you think about this guide?
Waste of time. I have written frequently that a couple of years ago Rhonda Wilson who authored the planted tank column in TFH said that any chemical actually strong enough to kill snails, snail eggs or algae would undoubtedly harm the plant. Given that these are not "problems" to begin with, but are the result of the natural laws of biology, botany and chemistry in the aquarium, proper maintenance and stocking avoids these issues or keeps them under control. Nature, not chemicals.
I do not think it is accident that my approach to fish keeping over 30+ years has been the primary reason I have had so few fish problems.
