    New owner. First fill - TA/PH issues

    A few things: If your FC is >10ppm, pH test will not be accurate and will register high. Don’t add boric acid until everything is balanced and stable. Adjustments will require more chemical after you add borates. I usually give acid about 30min to circulate without aeration to drop pH and TA...

    Adding pH down increased pH in hot tub

    Just did a clean/drain/fill on my hot tub yesterday.......pool is starting to get uncomfortably cool. Anyway, I was adjusting pH/TA yesterday too. It usually takes me 3 small adjustments to hit my targets. I usually circulate the first acid addition for 30min then aerate for 45min then test...

    Adding pH down increased pH in hot tub

    The pH down and alk+ are working against each other........even though you are adding them separately. My suggestion is stop trying to manipulate TA and just manage pH. When pH climbs above 8, take it down to 7.4ish. Eventually, pH will begin to stabilize because your TA is also dropping and...

    Take identical water samples to 2 different pool stores with digital analyzers........you’ll have your answer.

    Show off your AGP Deck please!

    Holy moly! Awesome deck/pool/home/property! What kind of carpet? What did you use as substrate?

    CYA & FC

    In a well managed pool that has always had adequate free chlorine, adding bleach at night is the most efficient use of liquid chlorine. But I think that bit of advice has been turned into “never add bleach at night” in some pool maintenance circles. Following TFP methods, you add bleach when...

    Best Overall algaecide

    Their silk guard pucks are pretty popular and they work great for a while. But eventually, there will be problems. Ingredients: Trichlor, Boric acid and a little Copper sulfate. Most silk guard users won’t care about the copper until it becomes a problem........Then they come here.

    (Update) Sand (dirt?) in pool, any other cause besides busted lateral/lateral assembly?

    It’s a possibility. I guess some varieties of zeolite are extremely brittle and somewhat fragile. Pool store who talked me into the zeo suggested I cover the laterals with pea gravel, then reinstall the zeo. My complaint wasn’t their first.

    (Update) Sand (dirt?) in pool, any other cause besides busted lateral/lateral assembly?

    I was talked into zeosand when I installed my pool and had the same issue. Do you have typical filter sand or one of the zeolite varieties? I recently changed to good old #20 silica and the sand on the floor disappeared.

    Wife just fired my pool guy - Want to make sure I am on right track cause plan on going it myself

    I don’t have much expertise to add to your situation other than suggesting you use the 10ml rather than the 25ml sample for testing chlorine. It is accurate enough and will save a bunch of reagent. Each drop = .5ppm.

    Experimenting...

    I use a Liquidator and I’m puzzled as to how it actually works. There are points when it is full and when almost empty that seem to effect the chlorine concentration being delivered to the pool. But, anywhere in between it is remarkably consistent. Did your suspended bottle of half bleach...

    Black algae problem

    We’ve all been there. Accurate testing + TFP resources = more time enjoying your pool........It’s that simple.

    PH and Alkalinity

    I see what you’re saying about the CYA, SWG levels. My take is SWG allows you to keep a higher CYA level to combat UV losses because it’s a steady supply, not that it requires a higher CYA level. When you are dosing with liquid chlorine, a lower CYA allows you a greater range of effective FC...

    As a self-proclaimed redneck engineer, I need to up my game a bit..........had no idea there were 91,000 drops in a gallon. 😎
