It took us several days to get our pool full and up an running due to a vareity of issues.
By the time it was full, it had turned a slightly cloudy green.
All I had done at this point is fill (over 3 days+) and add 1/2 bottle Poolmate Mineral out (Brown bottole) since we know we have iron and it was starting to rust almost immediately.
We also added 120# of salt, per the intex SWG manual and 1.3# of CYA per the manual (which seemed low). we then ran the pump for 24 hours.
We used our K-2006 and K1766 (salt) tests and came up with the inital results.
ph = 7.2
Salt = 3000ppm
CYA = 0 (not totally shocking since we just added the CYA 24 hours before)
CH = 200
TA - 190
FC = 0
CC = 0
We entered these values into poolschool and came up with the following action plan (intending to SLAM due to the green water):
ph = leave for now, since the TA was 190, and the target range was 60-80. recommendation for TA was to drop the ph to 7.2 and aerate. since our ph was already 7.2, we did nothing.
Salt = added 6# to bring it up to 3200
CYA = poolschool said to use 47oz. I subtracted 21oz that I added the day before and added 26 more oz, in a sock tied to a pool float.
CH = no action at this time
TA = keep the ph at 7.2 and aerate
FC = add 63oz. liquid 10% bleach
turned the pump on and the SWG (might have been a mistake, but we figured extra clorine wouldn't hurt)
We tested 4 hours later (after dark) FC = 12.5
Tested this am and FC = 13. The filter cartridge is pretty gross due to the iron that its filtering out and the water doesn't look a whole lot different. I can barely see the squares on the bottom of the pool.
Based on the criteria to quit the SLAM
You are done when:
- CC is 0.5 or lower; - check
- You pass an OCLT (ie overnight FC loss test shows a loss of 1.0 ppm or less); - check - maybe?
- And the water is clear. - FAIL
So, with all that said,
how bad did we mess up by using the SWG while trying to SLAM? could it produce more clorine than the algae would consume overnight? I guess we're not sure if we really have an algae problem, or if it could be some type of metals issue that's not covered by the Mineral out.
Is it normal for the CYA to read 0 24 hours after adding it? I see the note that it could take up to a week for it to fully dissolve, but I thought it would have registered something. My first addition was only 1.3#, which seemed weird. the CYA that I added in the sock doesn't look like it's dissolving very fast.
Are we on the right track? Should we turn the SWG off for now, keep SLAMing and just filter do it's work? We will probably vaccuum the bottom this weekend. but then we'll have to add more water, more mineral out...
Thanks for any advice you might offer.
