total chlorine 5
I have been opening my pool this year and had green algae to deal with along with having to change the sand in my filter. Now that I have new sand my pressure gauge that usually sets at 10 psi has jumped to 20 psi overnight. I back washed the pool and it came back down to 10 psi only to increase again. Also since back washing the pool I have a foamy layer on top of my pool. I have used a bottle 50% Algaecide and a bottle 60% Algaecide added gallon of 8.25% Bleach and 4 bags of shock. My water is slightly cloudy at this time but improving. I was told not to put in stabilizer until the water was clear.
