from a newbie on Whidbey Island, WA State (not very hot) and pool rarely occupied
1) if pool is balanced and clear, do I need to use algaecides?
looked at BioGuard banish (1qt 39.99) and BioGuard inhibit (1qt 29.99)
both say toxic to fish and other aquatic organisms and other things like remove contaminated clothing and wash before use, etc etc
2) are these prices fair?
3) if I have no visible problem, why put this stuff in the water?
both say for initial application do this and that, for routine maintenance do this and that
4) if I have no visible problem, can I skip the initial directions and just go to the routine maintenance directions?
