Today we tested another of the pools (in my signature marked as GM) using a "borrowed" Pentair test kit (pH and Chlorine only).
This SWG pool is one I commented in other thread that had some algea problem and I was thinking/asking here if it could be because of having very low "dirty" quality water from the "street" directly to the pool.
So finally we could test at least the pool (the kit ran over before we could test the water) and this is what we got:
I don't if FC would be the same as saying just "Chlorine"?
pH 7.0 target 7.5
FC 0.4 target 1.5
Pool capacity: 10,028.55 gallons
Pool surface: plaster
Pool get sunlight directly, BUT in this case, it has been raining not very hard over here for the last 4 days, no sun at all.
After consulting the Pool Calculator from here, got the conclusion that we need to add 700 g. or 25 Oz. of Soda Ash/Washing Soda (this is one thing available at this place for now; just taking over all the pools on my signature)
in order to raise pH by 0.53 and also TA by 18 (don't know at all what our TA level is, no way to measure it for now).
This would theoretically put the pH on 7.53
Also, to "fix" the Chlorine 0.4 (FC?), the calculator said that we should add 2.7 oz. or 75 g. of Dichlorine in order to raise the FC by 1.1, lowe pH by 0.04 and raise Salt by 1 (also don't know at all what the current Salt level could be for now).
This would theoretically put the FC on 1.5 and the pH adjusted to 7.49
Does this sounds ok for you?
I know that there are many additional considerations, but it's the first attempt (of many I think) to find out why this pool is the worse of all three
We will test again tomorrow but unfortunately we kit ran over... tomorrow we should have sunlight again.
