Read these and see if they help. Really glad the excessive chlorine demand is over. Now time to enjoy the pool!

Water has been excellent and thanks for all the advise.I use Back Up weekly but am having difficulty finding as everyone is switching to off brands.Any suggestion for a good algae preventer to replace Back Up

Glad things are going well. The ONLY algaecide we recommend is Polyquat 60%. Check the label. If it says:

poly [oxyethylene (dimethyliminio) ethylene (dimethyliminio) ethylene dichloride]

it's the right stuff!
