too bad i didn't have time to swing by Walmart and Costco today .. i could have run the gamut of soulless big-box stores. i picked some of the HDX Germicidal bleach .. totally appreciate the recommendation.

I went to both Home Depot, Fred Meyer, and Lowe's and found the following: any/all "Clorox Germicidal Bleach" has Cloromax Technology in it (see image), so i can't use that. the closest i got to a candidate for "pure bleach" was "Clorox Splashless Formula" (see image) .. but "formula" suggests...

it does, on the side. (see attached image) the image of the bleach that's the target of your "Clorox Germicidal Bleach" has the Cloromax logo on the front ... but when i look at it on amazon, it doesn't (the label on the bottle is totally different) .. it says "Now concentrated" with a yellow...

this is really helpful. my pool is small, indoor, and has almost no direct sunlight exposure .. and my sanitizer is clorox. so i'll let TA fall until it's more like in the 50-60 range and see if that stops my pH drift. i'll also add in a little CYA to stabilize the free chlorine .. but i'll...

this is incredibly helpful. i included that Sat. Idx. number for a reason .. i've been paying close attention to it, because as my pH rises, i get closer and closer to the high end of the recommended saturation index range - and that's allegedly where scale will form. that's my underlying...

here's the thing: my pH isn't stable .. it's continually moving up. and so that's sort of the core question .. either (1) why is it moving and/or (2) is there some combination of CH/FC/TA/CYA that'll settle it down? (it sounds like the guidance is: let it move up .. even to the low 8s .. which...

thanks Jim, i appreciate the guidance. three questions: 1. isn't the "ideal" range of total alkalinity 80-120? (and if so, isn't 60 a little low?) 2. isn't the "ideal" range of pH 7.2-7.8? (and if so, isn't 8.0 a little high?) 3. does it matter than my CYA reading is close to zero? (my pool...

See attached image that shows my test results for the past few days. A couple of things to note: my pH keeps drifting up .. such that I'm averaging ~3 TBSP of "pH Decreaser" per day. my Alkalinity keeps decreasing. Prior to the results I'm attaching it began at ~110 and gradually fell to 80. my...

I had similar discoloration in my pool. I drained it and used an acid-based cleaner (sulfuric acid i believe) and hand-scrubbed the entire inner lining of the pool. I did this for two reasons: 1. my algae appeared to have "roots", meaning, it was rooting itself the pool lining, and so i wanted...

Here's the thing about wanting to track this: my other numbers are all quite reasonable: C.H.:200, T.A:130, CYA:30, Temp:90 degrees, FC:~14ppm ... and during the SLAM, my pool was using maybe 5-6 ppm FC per day to as whatever algae was in the pool consumed it, which i replaced with liquid...

The title says most of what i'm asking .. a little more detail: in the middle of a SLAM, can i pour off say, 50ml of pool water into a container, add a couple of granules of "chem out" (which removes the chlorine) ... then, do a quick chlorine test to ensure i've removed it .. and then do a pH...

Since I'm obsessing over the details here, I have one more question: I usually use the 10ml test .. meaning, fill the tube with 10ml of pool water to begin. This tube is, much like winnie-the-pooh, short and fat .. and so it's meniscus can be a little tricky to line up. How much will the...

very helpful - thank you Dave.

i just started using a Taylor K-2006 testing kit and am at the beginning of SLAMing my pool. the Free Chlorine (FC) and Combined Chlorine (CC) tests involve using a tiny spoon to, and i quote "Add two dippers of R-0870", then "Swirl until dissolved". here's my question: how sensitive is the...
