Like many of you I have had problems for a few years with water mold and pink slime and this year I am trying chlorine. I almost changed my mind after taking the cover off last night and seeing how nice and clear the water was but I know it won't last all summer that way. Plus I like the smell of chlorine. I got all the good stuff ready to go including the various chemical tests and 8 cases of 12.5% chlorine. I am going to follow the directions on this site to convert but I have one question - I have iron and manganese in the water (which is why I first went with the Baquacil - it does not seem to cause any problems with the metals). Do you think I should try to deal with that before or after the conversion? It won't be an issue forever because I have just installed an outside silcock off of my water softener to periodically top up the pool from. Thanks for any advice!
