I come to the forums seeking the sage advice and wisdom of the pool gurus
I had an issue last year with my pool eating stabilizer and shock (I shocked with Bioguard Burnout 35 and Burnout Extreme) and I now realize that I closed at the end of the season without resolving the issue.
I opened this year to continue the pool saga and opened to a cloudy pool and I have spend easily over $250 trying to eliminate the chlorine demand issue without having it resolved (I opened April 2nd).
I have been going back every couple of days to the pool store and it was beginning to cost a fortune with no end in sight.
My last details (this morning) are as follows:
Salt Pool - 68,000 liters (18,000 gallons approx)
Salt Water Pool
Temp - 60 deg F (16 deg C)
Test Results via Bioguard ALEX program (I just ordered today the Borate Test Strips (Boric acid to be added tomorrow), SpeedStir Magnetic Stirrer and a Test Kit so I need to rely on testing from the local pool supplier until they come in).
CYA - 30
TC - 1.5
FC - 0
PH - 7.5
TA - 155
CH - 215
Mineral Level - 3400
I have shocked over several days (not hours as per the protocol) with the following (I realize that it was not done correctly and I was just throwing away money).
2 bags burnout extreme
4 bags burnout extreme
4 bags burnout extreme
10 liters (2.6 gal) of Florchem-19 Sodium Hypochlorite (liquid chlorine - I believe it is 12% but they did not know at the pool store)
20 liters (5.2 gal) of Florchem-19 Sodium Hypochlorite (liquid chlorine - I believe it is 12% but they did not know at the pool store)
After I did my pool test this morning I shocked with:
60 liters (15.85 gal) of Florchem-19 Sodium Hypochlorite (liquid chlorine - I believe it is 12% but they did not know at the pool store)
I slowly poured 20 liters (5 gal) of the chlorine, scrubbed the bottom and sides, poured an additional 20 liters (5 gal) and scrubbed the bottom and sides and did the same for the remaining chlorine. Pump floor drain only open and pump running on high with solar cover on after application was complete.
I will go to the pool store to get a water test after 1 hour for a baseline and again after 3 hours to see if the chlorine demand issue is resolved.
In frustration last year I discovered that I had very high phosphates and I used phosfloc and vacuumed to waste and the chlorine demand was eliminated earlier in the season and I could turn my salt generator down from 55% to 20% and maintain perfect chlorine levels.
I used phosfree this season (got it by mistake, I thought it was a floc) and I did not to vacuum to waste as per the instructions and the pool cleared right up but the chlorine demand remained (pool is still cold).
In using the calculator I only needed a very small amount of shock (1.7 liters or 56 oz).
Am I using the calculator wrong?
I have been shocking with substantially more and nothing has happened to the chlorine demand so I may have gone overboard with the 60 liters (15.85 gal) of 12% chlorine, but even using the 20 liter (5.2 gal) did nothing to resolve the chlorine demand and free chlorine was still 0 after the previous applications.
I have moved to the BBB method since I discovered the forums
Any tips, advice or insight would be very much appreciated.
Thank you in advance
