I am having problems opening my pool (had problems last year as well). 17K gal pool.
Last year when opening the pool was green and I needed a whopping 70 lbs dichlor before the FC would stay at 10 for any length of time. Needless to say, it took forever because I wasn't adding enough dichlor each time.
So this year I opened the pool on May 2nd and I thought I would hit it hard right from the get go. But I think I over did the initial chlorination using dichlor. I put in 30 lbs dichlor all in one initial dose. Needless to say, the chlorine test was "bright orange". pH was way low, just like last year. So I added 19 lbs baking soda and 7 boxes borax and the pH came up to 6.8.
I have not added anything to the pool since May 2nd. I keep the winter safety cover on the pool, so it receives no light. Circulatory pump has been running continuously since then. Water temp is at 58 deg F. Every few days I tested the chlorine and pH levels with a 3 way test kit. The chlorine has very slowly dropped and the pH has very slowly risen over these 17 days. So today (May 19th) I decided to read through these forums closer. I picked up a 6 way test kit at Walmart today to get more numbers.
Here is what I currently have:
Total Chlorine 4
pH 7.3
Total Alkalinity 200
Hardness 0
CYA 110
Obviously the CYA is way high. I have to think it came from the dichlor I added. Will the CYA level drop slowly over time on its own, or am I stuck with having to drain 1/2 of the pool water?
Very odd is that my Hardness is 0! Not exactly sure how this can be. I did the test twice thinking the test kit was wrong. I tested my city water with the kit, and its hardness is 100. So is my pool water hardness at 0 because over the past several years, most of the water has come primarily from rainwater and snow melt? Is this a problem?
The water cloudy/milky. How can I clear this up? Add more chlorine? Or do I need to drain 1/2 the pool?
