Hello TFP,
I’m in the planning stages of refilling our pool, the pool was emptied to facilitate major maintenance and the remodel of the back yard area, the pool is not new, is fully cured, and was not modified.
The pool is described in my signature line, but please let me know if I left out anything relevant.
After some testing, I can blend my well water with treated water to produce a ‘Fill Water’ with the following characteristics, the blending affected the CH and pH (very slightly) but little else:
FC/CC - 0.0
pH – 7.5
TA – 360 (Very high, I know, tested numerous times, this is accurate)
CH – 260 (Blended down from 460 at the well)
CYA – 0.0
Salt – 150
Given the values above, what would be the recommended procedure to fill the pool and attain the ideal water balance in the most efficient manner?
I assume I need to tackle the TA right away by adding muriatic acid to lower the pH to 7.0 and aerate the pool to return the pH to normal levels as the TA drops to the desired level (60)?
I also assume I need to slam the pool, should that be done before raising the CYA to the 70 to 80 range prescribed for SWCG pools in an effort to conserve chlorine?
Perhaps raising the CYA to 30 initially until the SLAM/OCLT procedure is complete, and then raising the CYA to 70/80 and adjusting the FC to 5/6?
Is adding the salt at the onset a non-issue although the cell will be bypassed, or is there an ideal time to add the salt?
The target water balance is the TFP suggested chemistry for SWCG pools, I am on the fence about Borate, but I'll tackle that once the water is balanced and ready to go.
I would like to get this right the first time without wasting time and materials, I would greatly appreciate any advice.
