    High CH and scale

    I think if you get your TA lower, 60-80 ppm, you may find that rising pH won't be as big an issue, and you'll be able to enjoy your waterfall again...

    Odd

    Doesn't work how? Diameters are incompatible or volumes don't match?

    Freshly filled pool water turned green

    Sorry you're having problems, definitely sounds like you were delivered water with a high iron content. Curious why you filled it by water truck? You didn't say, but I assume you're on a private well. An average well pump could fill that volume (20k liters, 5.3k gallons), in about 8 hrs - or...

    High CH and scale

    Totally agree with chief. Those numbers are fine. Test your FC/CC and pH daily... adjust your pH as necessary (and it will be frequent to begin with until your TA lowers), and your TA will fall in step. Keep your CSI in the -0.6 to 0 range, as this can actually reverse the scaling in the...

    Commercial sanitizers?

    My ACE sells 10% chlorine with date codes from 2016. I don't buy....

    How long before final water color is achieved?

    It will take a couple months of correct chemistry (mainly a slightly negative CSI) and curing of the plaster for the true color to be realized. Just like tile, the particles that provide the color to the plaster will be hazed from the troweling process - as this haze is dissolved the color will...

    What is considered a too high salt level in non-SWG?

    Depends what you are defining as "salt". A "salt", as defined in chemistry, is a neutral biproduct of an acid/base neutralization reaction. But most of us define salt as table salt (NaCl). It's also what your SWG needs, and what can make your water feel "softer". I know Pool Math shows the...

    TA level

    Alkalinity is the ability of your water to buffer acidic inputs. High TA will cause your pH to drift higher, especially if there is aeration of the water through water features, spa jets, etc. Low TA will not cause your pH to rise, and in cases where you have acidic inputs into your water...

    Vacation Risky Buisness

    Ya, congrats. I took a 2 week vacation back in July. Had a friend put in the prescribed amount of bleach twice a week, plus ran some trichlor tabs through the chlorinator (which I normally don't do). Didn't ask them to deal with acid additions. Came back to a clear pool with somewhat high...

    Question about raising alkalinity

    Have you added fill water, or do you have an autofill system that might be adding high alkalinity fill water to the pool. That's my issue with TA, my fill water has a TA of 390, so dealing with pH is just part of the game. Otherwise, your adjustment to TA may just be below the resolution of...

    Urgent help please!!

    Look for a cellulose fiber alternative to DE, FiberClear, ZeoFiber, etc... Might be more prevalent on your side of the Atlantic.

    Stenner Liquid Chlorine Chlorinator vs Salt Water Chlorine Generation

    This is a great pro/con analysis... might be a useful sticky post. I'd add in the cons of the Stenner solution - Liquid Chlorine degradation in storage reservoir... especially in hot climates. This can be offset by smaller reservoirs, but means more bleach lugging and less convenience. Also...

    Stenner Liquid Chlorine Chlorinator vs Salt Water Chlorine Generation

    Teal, I have come to believe as you. Mainly the liability aspect in the courts, which has come back to bite the pool builders, cuz it's easy to say "salt water" and everyone thinks "corrosion". Thanks

    Stenner Liquid Chlorine Chlorinator vs Salt Water Chlorine Generation

    Thanks all... all good replies. As I thought, there is really no wrong answer, which makes it all the harder for me to decide. Anyone have any clue why pool builders of gunite/plaster pools steer people away from the SWG systems. I get there could be issues when natural rock is concerned...

    Cloudy/Milky Pool. Is My Filter Too Small?

    Ya, raising your TA to 60-80 (baking soda), and CH to 250-300 (Calcium Chloride) wouldn't require you to drop your FC, and it would bring your CSI back into the recommended range - and keep your tile grout safe.
