Our liquid chlorine plus CYA from pucks pool measures around 700-1000ppm salinity, but that is partly because it's vinyl so I don't worry about CH on the low side

It's moot now as I've found the s200 here for 17% off. Still more than double the US price, but that is what we get here for low volume items!

Anyone in Aussie or NZ know? they appear to be maytronics made (on a googled review), the Hydro looks like the s200, Ultra s300 etc to me. Waterco Cleaners

We recently got a solar cover and the reduced gas exchange (presumably) has basically stopped the upward pH drift that occurred prior to the cover. I've had to purchase some pH increase for the first time! The carbonate equilibria in pools for a given alkalinity is driven by the partial pressure...

The MSDS sheets are the Taylor ones so these Clear Choice refill reagents are identical and I can just buy as needed for the Taylor 2006-C kit I inherited which is great!

You're right - thanks!

Yeah - this is interesting. Obviously with any Alkalinity in recommended range pH tends to rise due to outgassing (slower in winter with temperature and rainwater dilution). This is what happened consistently with our pool - I've never owned any Soda Ash! But since installing a solar cover as...

Thanks - our liner is old from when we moved in anyway, so maybe a new, larger pool in our future. We're in Auckland which is almost identical to San Francisco in temperature except our winter minimums are a few degrees higher...so no close down, just no swimming unless we get a heater.

Yeah - my point was not the filter pore size of DE but that if there are 10 micron DE particles and sand filters only catch down to 30 Micron, then some of the DE may go through the filter and end up in the pool like other fines in a sand filter

Ahh: Do you ship overseas? No, due to shipping regulations regarding chemistry, we do not ship overseas.

Thanks, yeah I have bought the pool math app so familiar with those....but was more after at what pH/TA levels and durations does the Vinyl liner start to be negatively impacted in terms of lifespan etc?

Thanks - the reason I asked was quick google suggested DE centers around 10-200 micron particle size and sand filters filter down to maybe 30 Micron...although maybe Heated / pool DE is not so fine?

Do you have a ref for this and what are the appropriate pH / TA limits for optimal vinyl liner lifespan? Thanks!

Any chance of TFtestkits shipping to NZ?
