You have a vinyl pool with no heater- you don’t need more calcium for any reason.I understand- but in my case my calcium hardness is very low- and as mentioned I have NO heater- BUT then wouldn't adding this Powershock powder-(calcium hypochlorite) make my calcium level a bit BETTER- and make the water better if i do this method infrequently?
Too little ch is not an issue for your pool.
Too much is a problem & can cause scaling.
My main point is - Why add something you don’t need just because?
You’re not logging your results in
PoolMath so I don’t know your current ch level to guide you on how much more ch you can stand.
The cal hypo will last indefinitely if stored properly & doesn’t degrade so just save it for backup if you can’t get liquid chlorine.
The yellow oto test is not a very accurate test - its more of a “do i have any chlorine or not?” Kind of Test (fc or cc? because it cannot tell the difference)
It is included mainly because of the comparator block for ph. For most people with normal amounts of cya it offers too low of a range to be very helpful.
Use the fas/dpd for testing fc & cc separately & accurately.
If you need more reagents/powder order them before you run out.
