the most likely culprite is chemical or biological chlorine uptake. something in your water isn't allowing you to achieve break point chlorination ( the point at which you can measure free chlorine). This could be due to ammonia, sulfur, iron deposits or some other chemical in your sourcewater that is "eating up" your chlorine.
well when you leave your pool covered for the winter, you are unable to put chlorine into it. Chlorine prevents algae so to answer your question, the lack of chlorine causes algae
Do you have a chlorine generator? No.
normally when there is no reading for chlorine means that you need it, put 1 gallon of liquid shock in your pool. that will raise the chlorine level, cheryl
there is shock you can buy from the pool supply store and also put lots and lots of chlorine , don't swim in it or let anybody swim in it for at least 2 to 3 days depending on how much you put in there.
try it out and tell me
Bromine is an additive that you put in a pool to sanitize the water. Chlorine is an additive that you put in a pool to sanitize the water. Salt is added to some pools to allow it to be converted electronically to chlorine with a salt water chlorinator.
That depends on what size pool you have. If you have a smaller pool, the amount would be less, and if you have a larger pool, the amount is more. Consult the instructions on a chlorine box for what size pool and how much to use.
Measure it out then dump it in. It will gradually mix in.
No, Chlorine would kill them.
