Hello to all,
Let the pool guy go in Dec and have been doing things myself...I have been using 8% bleach and 32% M-Acid to keep the pool in spec.
Well, I just did a set of tests w the TF-100 Test Kit & Stir-stick, here are my results:
FC = 2.5
CC = 0, so TC= 2.5
CH = 437.5*
TA = 40*
CYA = 40
pH=7.2-7.3
water temp 68-70
16K gal in-grd
water visual - crystal clear and no issues w algae or pebble-sheen spotting w either light or a bit darker splotches - pretty uniform
* tested each of these twice
pool was filled w water in jan/feb 2015 for first time
I had an issue w the pebble-sheen discoloring last summer, so the gunite company did a no-drain acid wash for 8-9days...it fixed the problem. He told me to keep the pH is the lower range of 7.2 -7.5 so that's what I've been doing...I think this is why the TA is low, yes?
Since the pool guy was using pucks and I only liq CL, my CYA has dropped from 60-65-70 to 40. I've only used liquid bleach for last 4-5 mo's..I made the pool guy take out the pucks the last mo he was here and use liquid CL
I believe the TA is low bc the acid levels have been kept lower...I'm going to ask the gunite guy can I now keep the pH a little higher to 7.5
I have noticed that the consumption rate of the CL is going much faster, prob due to lower CYA value, water warming and decent runs of a lot of sun-light. In the winter, we had a lot of cloudy days and rain...I did not swim in the pool during winter, but did use the spa here and there and it empties into the pool
So, what do I do to get the CH down to 250-300? I let rain water fill the pool many times in late fall and winter, and my only other option is the city water. I'm sure it's mineral rich. I might want to get the gunite guy out and see if he thinks the plaster/pebble-sheen is done leaching CH from being a new pool.
I would appreciate your pool chem experience on what I need to do? Thank you very much, tstex
