Hello, I had a older (1979) plaster diving pool for many years and I (or my ex-husband) just always used 3-4 chlorine tabs and would add shock and muriatic acid. Well I moved 3yrs ago (it’s now just me trying to figure this all out and I’m getting fairly overwhelmed) and got a new much smaller pebbletec pool built. They left me with a starter small bucket of chlorine tabs and then scheduled for a guy to come out the following week to walk me through all my equipment. Well during that the guy told me not to use chlorine tabs and only liquid chlorine. Well I was very confused and had already started with the tabs (and bought a huge bucket) plus like I mentioned I had always used them for 18 years in my other pool. My parents had always used them as well. I kept using them and had considered hiring a pool service and had my neighbors pool guy stop by and one or 2 others and they all said they use the tabs and the dip test strips. So I didn’t hire anyone because I thought well I have plenty of tabs and I have the test strips so why pay them. Well by end of first summer took water to Leslie’s to test and they told me I have to drain it when it cools down as my CYA was way too high. Granted I didn’t realize I was adding 3 tabs to my much much smaller pool (7,200 -7,500 gal). So this past February I drained it almost all the way but was still using tabs but just one tab at a time. For the first several months I took my water to Leslie’s to have tested once a month and their water “percentage grade” was 80% then it went to 60% then down to 30% because my CYA was way too high again. And then the constant PH low Alkalinity too high, then i would get the PH up and then AK was too low so then Leslie’s would sell me Alkalinity Up. Struggled all summer and Monday night our temps fell to 50 and our high was 70 so I took the opportunity (by Friday we’ll be at 90 again) and I drained my entire pool. It finished filling back up tonight. So now here I am and need help. I have MA & LC, and of course a ton of tabs. I have not put any in it yet. I’ve read on here I should use LC and not tabs cuz of the stabilizer in the tabs (right? I’m still learning) because that doesn’t burn off and builds my CYA, right? I’ve ditched my dip test trips and my order arrived last week (TF-100 Test Kit, Smart Stir, pH Meter, and Standard Sampler. Although I am a bit intimidated by it all and I have idea how to use the smart stir or PH meter. I will never go to Leslie’s to test my water again (I read what many of you have posted about them, and they were frustrating the Crud out of me before find this wonderful site).
I am in Arizona and so my one concern is if I use LC, I’m not sure what I’m supposed to do during the summers because it’s so hot here when I’m gone for several days or a week and am not here to be able to add LC every day or every other day. I don’t live anywhere near anyone that could help/stop by when I’m gone. So not sure how to manage using LC in the summer especially.
Last question for now, so why do so many pool services and probably millions of pool owners use chlorine tabs with stabilizer for many many years? If it’s not great to use why and how is it not more common place for everyone to use LC instead? Do all these millions of people have continually pool water issues then? Everyone I know says they all have used the tabs for 10-20 yrs and never had water balancing issues. I don’t get this.
I would so appreciate any help & direction.
