Total alkalinity 260
Cyanuric acid 200-300
Calcium Hardness 500
Free chlorine 0.5-1.0
Combined chlorine 1.0-2.0
pH 7.2
Water temp 82° F
Air temp range 100° daytime, 50° nighttime, intense sun.
Water appearance crystal clear, sparkling
Believe it or not, those are the real numbers.
Water generally looks good.
Water always smells good.
Pool equipment runs 4 hrs each morning. (8am-noon)
Last year and this year we cannot keep the pH up.
Last year and this year we cannot keep the FC up.
The first 3-4 years we had to add acid weekly to correct the pH.
We have added 10-12 lbs of soda ash and 1 lb of baking soda over last season and this.
Except for baking soda and soda ash which come generic from Walmart,
pool is treated with Bioguard brand products.
We've had green algae, but was taken care of with algaecide, algae killer, and shocking.
Prob 1: pH won't stay up
Prob 2: FC won't stay up.
Prob 3: We know have a stubborn 'red algae' growing on the plaster surfaces.
Any suggestions?
