I've been keeping my pool crystal clear, at 88-90 degrees (wife's choice not mine) so far just by monitoring my chlorine levels. Chlorine source is liquid 10% chlorine that I buy for $4.00 a gallon at the local hardware store.
Haven't been using trichlor or shock for a few months now.
Recently, I noticed an itchy feeling while in the pool and after. I've also noticed my pool is still clear, but not crystal clear as it was. You can still easily see the bottom drain but it is less clear than it was.
I ran tests and put the numbers into pool math, here's what I got:
TC 3.5 (corrected)
I know I'm low on chlorine and have added more to get levels correct but I'm not familiar with some of the other additives recommended.
Pool math says:
FC add 46oz of 10% chlorine (done)
PH 240oz of soda ash or 48oz of Borax (where would I buy that, grocery store?)
TA 282oz of Baking soda (grocery store again?)
CH 124oz of calcium chloride or 99oz of calcium chloride diyhidrate (I googled it but am unsure where to actually buy it)
Before I located and put all these ingredients into my pool, I thought it may be wise to double check here. Seems like a lot of product to me.
