Low Ph and Chlorine in salt water pool

[Yeggim]

I think you're off on your volume of water. An 18' diameter by 4' depth comes to 7,600 gallons.

Bought a 6 way testing kit this morning and tested the water a few minutes ago. The Ph is showing between 7.5-7.8 almost 24hr after the added Borax. I had the SWG running for about 7 hours from this morning and the CL is at .5.

Ph: 7.5/7.8
CL: .5
CYA: <30 (the water wasn't cloudy in the test tube)
TA: 30

So it looks like I need to get some numbers up here. So Doc, should I still go the course of what you recommended earlier?

Yeah, I think so. You need to keep chlorine in the pool overnight, at least, in order to avoid algae while you get your stabilizer up.

I also think you'll need avoid thinking of the SWCG as your sole source of chlorine.

Sorry, I'm sure the manufacturer is correct. I assumed that 48" was the actual water depth.

I think it's like that because it's not fully cylindrical (hershey kiss shaped) so that calculation won't work. Thanks for bringing that up though! I've seen the manufacturer wrong before!!

Ben/Others,

Thanks for your help and tips with my issue. Believe it or not, last night I soaked the titanium plates of my chlorinator in vinegar, rinsed them off, saw a little bit of crap come off them. I'm pretty sure they haven't been cleaned over the past 4-5yrs since this has been in use from my in-laws. At any rate, I ran the generator as normal last night and now I finally have a chlorine reading. It is around 3 now which is will work, and I plan on checking it again later today to see how much it changes.

As for the Ph level, it is currently maintaining at 7.5, thanks for the tip with the Borax!

Now if it would stop raining and get hot again I can go for a little swim!

Glad things seem to be working out!
