    Way to directly test if Bromine is present?

    I deleted the old post so it's never is an issue again. I have a love/hate relationship with old threads. Sometimes they aged well, other times notsomuch. Or the new reader doesn't inherently understand how the old OP's pool is different from theirs and that advice.......... if it aged...

    Test Kit Arrived

    With regular testing the light bulb will go off quickly that you've been losing 2ppm (?) a day now, then slowly increasing to 4 ppm per day in the peak season. Then for the back half it slowly decreases each day back to little daily loss in the late fall. Adjust dose as needed.

    Test Kit Arrived

    Also. FC is a moving target with less daily demand now and more in the peak season. 'Target range' is for that reason. 2 FC may still be a 2 day supply, yet only a 3 hour supply in July. You want : Minimum FC + Recent daily loss + 1 or 2 ppm wiggle room...

    Test Kit Arrived

    Walmart / HD / Lowes has CYA (stabilizer) in 4 or 5 lb bags. Pool stores may or may not have a good deal. Make sure it says 100% cyanuric acid in the ingredients. Add 15 CYA per . Hang it in a sock, carrot on a stick like, in front of a running return. Some time later or even...

    CSI vs LSI and effect of a negative CSI on a pool heater?

    Got pics of the liner wrinkles ? Is it big folds or a million little ones like a fingerprint? I ask because the fingerprint wrinkles are from really low PH (usually over winter for liner people) and that water may have sat in the heater.

    What to do with Old Liquid Chlorine

    My leftover bleach gets used to clean my PVC fence, vinyl siding and any outdoor furniture that needs it. It can be weak and still works great for that stuff. If I have any left after that, it gets delegated to the laundry room where it'll be effective for a long time.

    Clarity issues post opening this year - Out of Ideas

    So you can kill or mostly kill all the algae and the FC holds. Then it takes time for the filter to do its thing and remove it all. You keep the FC up throughout, or you risk losing the upper hand in the battle. Plus, the daily brushing and vac job may expose new layers of algae on the...

    Small Stain

    Ultravioletlightium works, but it takes a little while. On a serious note, so does hydrogen peroxide, but there is no need to lower it. Have a beverage and wait it out. Daily losses are still low most places so it's easy to climb high, especially with an oversized cell. It is totally...

    I mean. Don't get me wrong. You are 'free and clear' above min, like I always preach. That's really the important part. But it's a but much. :ROFLMAO:

    Question about order of importance on test results

    Well. I think you quoted it wrong. You can test to 10 CH increments by using a 25 ml sample, or to 25 CH increments by using a 10ml sample. The size of the sample determines whether each drop is 10 or 25 CH. We have zero need for 10 resolution. Heck. 25 is probably closer than...

    Guidance needed, 3 years using TFP and I am at a loss (Solved)

    10 to 20 with a similar light orange to dark orange. Then it goes brown around 20. (Give or take as the test itself has a wiiiiiide variance)

    Second Week Ever Testing - Next Steps?

    +1. 3000 to 3200 is enough for ICXXs. 3400 is wiggle room for the spring showers to dilute it a little with overflow.

    As your CYA increases, the FC must increase proportionately to match, to sanitize at the same level. All lines on this chart are equal for sanitizing . Please read :

    Second Week Ever Testing - Next Steps?

    This is what it has on it. Put acid in your cell, every 3 months, whether it needs it or not. :roll: There's your proof they don't even know what they don't even know. Or they do know, and want to sell you more cells because they ruined this one. Scrub any recs from them or the...

    Blue Surf pebble sheen turned grey

    We see fading and bleaching all the time. I can't recall a finish that was erased completely, even with an acid wash. You filled at the height of the shortages, when quality control went to crud. It seemingly didn't matter how bad any product was as long as the company got a product...

    Blue Surf pebble sheen turned grey

    Ok. They just like to scare you into expensive treatments. Or to drain to cover their foul ups. a 110 would peg the machine the same as 400. Don't shoot the messenger but it's the methodology, not the service company or pool store. Everybody is on their Nth service company. The...

    Blue Surf pebble sheen turned grey

    Very high isn't a value. Do you have a # ? If anything, high CYA would help keep the pool finish not bleached out. They would have had to bring it to an absurd FC level (like 100 or more) to risk any damage. But we just saw it yesterday where a pool store was recommending 30 bags of...

    Stumped!

    I always tell folks that maintaining slam at the end takes little effort and starting over takes lots of effort. If I ever need to slam again, I'd hold SLAM 2 full days after passing the OCLT. Congrats RT. :)

    My pH still rises really quickly and it concerns me

    $34 scale with bowl (Bleach as example). The bottle weighs 10lbs, or 1.25 oz (weight) per 1 oz (liquid). Half a jug is 64 liquid oz or 80 oz by weight, no matter how full the jug started. 28 liquid oz is 35 weight oz. (Etc etc)

    My pH still rises really quickly and it concerns me

    What about a digital scale that can handle 10 lbs ? I'm pretty sure my kitchen counter scale could handle it. Weigh the full bottle and maths that each liquid oz weighs X, then pour and conform it lost X oz by weight. Everybody gets a feel for it after a while, or they get lazy...

    Chlorine Question

    Yes. Carry on as you've been. (y) I agree the CYA is probably still higher, but without proof, we risk plaster damage if we guess too high FC for your CYA. Nate ships everyday. Barring a UPS/USPS issue, we'll know real soon. My refills were coming Friday and something happened in...

    Look into the bottle with the sharpie lines outside to give you a roundabout that it was half, 3/4, etc.

    My pH still rises really quickly and it concerns me

    Sharpie the bottle with 10ths. Then double check you're pretty close enough to the line you wanted to stop at.

    Featured Raise ph before SLAM?

    It can go alot of ways and none of us are psychic. (I'd wouldnt be able to help folks because i'd be too busy playing lotto for a living myself) :ROFLMAO: IMO ammonia is so easy to prove/disprove it makes sense to start there. Once we have reliable data.

    Featured Raise ph before SLAM?

    Abort mission !!!! You'll have to forgive Gene above for being a desert dweller who doesn't close. Us northerners need to verify there is no ammonia when opening with your current experience. Once the test kit comes, Get 10ppm FC in there per. Mix and test 30 mins later. If most of the...
