Algae & Cloudy Water

[pjohnson73]

I live in Florida and with all the rain lately and working 12 hour shifts my pools had some algae. I have gotten it to clear some but can't quite get it beat. I have an Intex 16X42 pool, pumps 800gph. My readings from Pinch a Penny yesterday were the following:

FC-5.0
pH-7.8
Alkalinity-120
Calcium-200
Stabilizer-95

I'm not sure what quite to do. I have been shutting the pump off every 3 hours and cleaning the filter and brushing the pool to stir everything up. Is there anything else I can do? It looks a lot better but I want it clear again. It is also a little cloudy. I also shocked it this morning.

Thanks for the help.

With your stabilizer (CYA) level so high it is going to take extreme amounts of chlorine to kill the algae. It would be much easier if you lowered your CYA level first. Unfortunately, the only practical way to lower CYA is to replace water.

How often should I shock it then since my CYA is so high? My pool is about 4000 gallons.

First, you should take a look at the FC/CYA chart, which shows that you need to bring FC up to about 37 to fight algae with your CYA level.

Then you should read this article on fighting algae.
