I've just installed an Aqua Rite SWC generator on my pool. I'm on a fresh fill from well water that is high in CH & TA. 350 & 380 respectively. I filled last week and I have been adjusting over the past 5-6 days to get the balance right before I fire up the cell. Here is what I have done so far:
Fill: 4/08-4/10 Approx 36,000g from my well.
Test 1: 4/12
PH 6.8
TA 380
CH 350
Started circulating the water on Saturday 4/12 also. D.E. filter was cleaned & recharged.
Sunday 4/13 added 8lbs. of Cyanuric Acid stabilizer, 7lbs Dichlor. granular shock.
Test 2: 4/13 (About 6 hours after stabilizer add.)
Cl >10
PH 7.5
TA 360
CH 350
CA 55
Monday morning 4/14. Started aerating water and dumping acid. My pool should have good aeration with 3 waterfalls (18" sheer decents) and 2 spray heads that I've aimed at the water to entrain as much air as possible.
Test 3: 4/14 (Before acid)
CL >5
PH 7.2
TA 310
CH 350
CA 55
Test 4: 4/14 (About 2hrs after 2g of acid)
PH 6.8
Good. Went to work with the low PH water bubbling away.
Test 5: 4/14 ( Home from work 11:30p)
CL >5
PH 7.5
TA 280
CH 350
CA 50
Let it run overnight
Test 6: 4/15
CL>5
PH 7.5
TA 280
CH 350
CA 50
Dumped 2g acid.
Test 7: 4/15 (2 hours after acid.)
PH 6.8
Went to work and let it continue the aeration.
Test 8: 4/15 (Home from work 11:30p)
CL >5
PH 7.2
TA 260
CH 350
CA 50
Tested again this morning snd guess what?
Test 9: 4/16
CL>5
PH 7.2
TA 260
CH 350
CA 50
I've just dumped 2g more acid & checked.
Test 10: 4/16 (Of course I waited)
PH 6.8
Am I doing things right? I feel as though I am. This is the first time I have tried the low PH/aeration method of lowering TA. I'm finding out that the key is patience! This does not work overnight. At least not for me. I'm very interested in hearing from others who are more familiar with this. Do these readings sound right? I'm not really doubting my testing accuracy, I'm just wondering if, for a pool this size, do the ammounts of chemicals added seem right? I'd just like a little reassurance before I continue to dump gallons of acid, that I'm not doing something stupid without knowing it.
If anyone gets to the end of this post and has actually read through it all and replies, GOD BLESS YOU ! You are a meticulous person and obviously dedicated to advancing peoples knowledge of pool chemistry.
