Currently my numbers are: FC - 7 CC - 0 pH -7.5 TA - 90 CH - 160 CYA - 45 FC drops to around 5 by the end of the day. I'm going to have to use some Calcium Hypo to get the CH up a bit, but other than that I think we are all good.

Thanks for the quick reply. Did a search again and tracked down a bit more info pretty much as you said, it doesn't matter :) Any feedback with regards to chemical addition or does that not matter either? I'm pondering if adding them in the evening might not be better as you would have your...

After 2 years of water restrictions we finally have a summer where we can use the pool properly. Woot!!! I managed to get a TF 100 XL on a visit to the US and am all set. Water is looking good after just 4 days and I saved a bunch in chemicals in knowing that I did not need to shock for days...

Indeed, I have a hugbug pool cleaner that runs just fine under the cover.

Went to the pool store and had the water tested after the drain: TDS - 1000, down from 1700 FC - 1 CC - 0.5 pH - 7.8 TA - 40 CH - 515, down from 1280 CYA - 0 I'm pretty sure that the first CH of 1280 was an over read, they tested 3 times on this visit and all I can say is that I am happy it has...

Thanks for the great advice. I tested the pH a few times during the refill, with 0 chlorine, and it seemed to be increasing slowly with time. I have added the acid and chlorine, gonna leave it overnight and take a test sample to the shop tomorrow. Hoping the Calcium has come down nicely.

Ok, so I've done the first drain and almost complete with the refill. There is a fair bit of black algae in the pool. I gave some of it a good brush when the water was down and I was surprised that a fair bit of it came off quite easily. There is still a quite a bit left... I'm wondering if I...

Thanks for all the friendly welcomes :cheers: With regards to partial drains, is 1m an ok place to start or should it be more like half a meter? Shallow end is something like 1.2m and deep end is 1.9m - 2m. If I do spring the $ for the test kit, it was suggested that I get extra CYA and...

Indeed, I am in no rush. I guess I just need to keep an eye on the pH to prevent scaling. I certainly will not be draining the pool, which was my first thought, since I discovered the water table issue. It's midnight so I'm off to bed :sleep: . Thanks for all the replys so far. David

Well, we were close to water restrictions a short while back but have recently had good rain so we should be good for a bit. I do feel bad about having to dump so much water but the more I'm able to dump on the first go the less I'll dump in the long run. Also thinking that since I am able to...

Hi there, Never had a pool before and have just purchased a home with one. Have spent the last week or so reading as much as I can to get my head around what needs to be done. We are in Winter here (South Africa), pool temp sitting at about 58F so no swimming until November probably. Ordered a...
