I have a gunite inground pool - 25,000 gallons. 4 years old.Current readings are:

PH: 7.4
TA: 130
CYA: 100+

I have had clear water all year - no problems. A couple of weeks ago I turned on the solar heating to extend the swimming period - I live in California so pool is open all year round. Pool was being kept at around 83 degrees. Noticed algae last week so dumped in 5x3quarts of bleach, brushed pool and cleaned cartridge filter. Put in another 3x3quarts 3 days later as pool was still somewhat cloudy. Then another 2x3 quarts yesterday. Been running the filter from 9am to 12 midnight. (equipment is near property boundary so concerned about noise to neighbour) Chlorine level is approx 25ppm (tested on Guardex kit using pool water and distilled water method) but pool is not clearing. What am I doing wrong? - this method worked last year which was the last time I had algae. Solar heating turned off and pool now running at 76 degrees. I know that my high CYA reduces the chlorine affectiveness so have kept chlorine levels about 10-12 throught year. I "shock" with bleach and also have trichlo pucks in online feeder. Should I put in more bleach? - will that damage my pool? Many thanks
