Hi,

I moved into a house with a pool last year and I have no idea how I kept the pool looking decent most of last summer, I just dumped in chlorine when it looked like I needed it and put some 3" tabs in the Hayward CL200 feeder.

But this season, I'm already having a very hard time keeping the algae away, and even when I got rid of the green, the water has been very cloudy and the green seems to just keep trying to come back. I do have the drop and vial type test kit and tested today. Below are the results and other info.

Also, last year I took a sample to a local pool supplier (chain) and some kid said I needed about $180. bucks worth of all kinds of bags of stuff. I chose not to listen to him and just got some more chlorine and tabs. I really need to get this under control and maintain it as inexpensively as possible as money is very tight at the moment. I really want to learn all this and be very good at it.

Happy to provide any other info needed.

Please advise on what I should do, thanks very much,

Steve


Pool is in ground, approx. 20,000 gallon

3 inlet jets, one skimmer
Jaccuzi cartridge filter (I wash cartridge regularly)
Hayward CL200 feeder set all the way open to number 7 on dial, I maintain 2 to 3 tabs in it
Pump set to run about 6 hrs each day (I sometimes run it 24 hrs at a time)

Test results:

FC= 3.0
CC=3.0 (combined chlorine)
PH=7.4
Acid Demand= did 35 drops of solution 3 and still no change in color
TA= 7 drops of solution 3 then turned clear
