    Pebblecrete and Calcium Hardness

    Yes I understand, I'd rather protect the chlorine generator. May I ask what CH level would you aim for in this case for the long term? Thank you

    Test Kit Australia Recommendation 2023

    Hi all, What is the recommended test kit for Australians at the moment that is good as well as good value for money? I have found a kit online from Clear Choice Labs called Total Pool Water Testing Kit, Salt Water (AUD $205)...

    High Chlorine Level on Jet Vac Cleaner, Solar Heating and Swimsuit

    Hi all, I've recently performed a SLAM due to heavy rains and garden water runoff making the pool cloudy and slightly green. 3 days later it was fixed after adding 3 batches of liquid chlorine (15L - 4 gallons, 7.5L - 2 gallons, 7.5L - 2 gallons) during two days), lots of brushing and filter...

    Ideal CYA Level in SWG Pool

    Hi all, I've been reading some great information on this forum. My understanding is the recommended CYA level for a SWG pool is 70-80ppm. But if I can aim for a particular target, is 70ppm or 80ppm preferred for my pebblecrete SWG pool? My pool water chemistry at the moment is: FC 5 pH 7.7...

    Pebblecrete and Calcium Hardness

    Hi all, I would like your opinion please on what is the highest Calcium Hardness level I can have in my pebblecrete pool? I have seen a lot of conflicting information which makes things all the more confusing. The TFP PoolMath Calculator says for SWG and Plaster pool surface (not pebblecrete...

    SWG with only pH probe - Ideal CYA Level Changes?

    Hi all, My aim is to constantly have a HOCl level of 0.05 ppm (to kill bacteria and algae) as well as to "balance" the water according to CSI. I have a Pebblecrete pool with SWG (with pH probe only). If I keep a pH level of 7.6 and CYA of 70, what Free Chlorine level do I need to achieve a...

    SWG with only pH probe - Ideal CYA Level Changes?

    Thanks for that. How can I calculate the HOCl value if I have FC level of 8 with 70ppm of CYA? Is there a formula I can use where I can adjust different variables such as pH, FC, CYA? My aim is to have HOCl level of 0.05 ppm as well as "balance" the water according to CSI.

    SWG with only pH probe - Ideal CYA Level Changes?

    Hi all, I've been reading that for SWG pools, the ideal CYA is 70-80. For bleach pools, ideal CYA is 40-50. I have a SWG (Viron EQ 25) pool with pH probe only. There is no chlorine or ORP sensor. Does this affect the CYA ideal level for me? My concern with raising CYA to a high level is...
