Having an issue getting my CH back into range after a changing filters this spring. Before I replace the filters it was always too high around 700-800. After the filter change back in April-May it slowly drifted down into target until last month when it went to below. At the low point while waiting for chemicals it was 70-80 and at the point below 150 for about 3 weeks.
2 weeks ago I got my first shipment of Leslie’s Calcium increaser 45lbs. I added the entire 45lbs over the course of the day with little change other than salt levels increased. Also the levels started really dropping when attempting to bring CYA into proper levels using BioActive (which seems to work some), chose to try that as water is very expensive in SoCal.
Pre bio active numbers after a shock by SWG:
FCL 9.21
TCL 9.21
PH 7.2
ALY 133
CH 168
CYA 140 Estimated I can only read 125 max
Salt 3700
Temp 79.7
I then waited 1 week for FC to drop within range to use BioActive.
Test prior to addition of BioActive on same day:
FCL 1.85
TCL 2.18
PH 7.1
ALY 94
CH 117
CYA 125+
Salt 3600
Temp 74.7F
3days after BioActive:
FCL 3.89
TCL 3.89
PH 7.1
ALY 94
CH 116
CYA 100
Salt 3600
Temp 75.7
8 Days after BioActive + 45lbs. Calcium chloride: (pool begins consuming chlorine)
FCL 1.27
TCL 1.39
PH 7.4
ALY 94
CH 131
CYA 116
Salt 3800
Temp 75.2F
After ten days I added second bag of BioActive as CYA stopped dropping (pool continues consuming chlorine and calcium or calcium is binding with salt)???
FCL .63
TCL .68
PH 7.0
ALY 94
CH 120
CYA 125+
Salt 3900
Temp 74.1F
Six days after second BioActive treatment and 90lbs. Of calcium chloride.
FCL 2.84 (SWG running at 100% for 12hrs per day vs normal to maintain FCL at current test level of x.xx of 40% for 6 hrs)
TCL 3.13
PH 7.1
ALY 78
CH 96
CYA 118
Salt 4200
Temp 70.2F
Any ideas? BioActive should be dead in 4 more days. Very little algae growth, water is crystal clear. Is the calcium combining with the salt, is it being deposited into the tile and plaster since bringing below 150 for a short period?? I doubt the BioActive would consume it but who knows?
Would like to clean my filter or at least open it up to see if there is a huge deposit of calcium stuck in it. That’s the only other place I can see it disappearing to. Not sure why the chlorine consumption started either we just had SWG replaced as the ten year old on just died a week prior to this starting which is when I did the shock with the first numbers above.
Pool is 30,000 gallons in SoCal, Plaster and tile with attached spa.
Any suggestions or where to go from here?
Anyone seen this before?
Thanks,
Scott
