Do you do the CYA test...with the tube/dot... in the direct sun, or in the shade? I would imagine one versus the other will influence the results

I took a water sample across the street to a pool store to confirm my readings were accurate - and everything is spot on except my CYA... which they tested at 95 (n)

I live in AZ and the temps here have been pretty hot (115 ish). I was out of town and when i returned my pool had a bit of algae starting to grow on the floor/walls late last week. Water didnt look too bad though. I have 4 pucks floating (i'm aware of the CYA implications). After a thorough...

When i select the drop down on the FC section of the calculator, i get the following options - Dichlor - Trichlor - cal-hypo - lithium hypo - chlorine gas which should be used to calculate the FC using bleach/liquid chlorine?

I'm currently refilling my pool, and will need to setup the water over the next couple days. I've been using the TF100 test kit for some time, however I have a question about this site's "PoolMath Calculator". My pool is 13k gallons, and I'll be adding some stabilizer to get the levels up to...

It was a 10ml sample

just redid the FC test. It took 90 drops of R0871 to turn light pink/clear

The pool water hasn’t been chlorinated since December (up until now). the reagents have been stored indoors in a cupboard for 2 years... just seems odd how far off everything is measuring

I i used the CYA test from the TF100 kit. Pulled the water from the pool this morning. Why would the FC test so high then if i only put in 2 gallons? Can the test kit/chemicals go bad? I’ve had the kit 2 years or so...

We had our pool resurfaced/new sand filter about 2 years ago. i haven’t kept up with any chemicals over the winter, and just started getting it ready for spring. The surface had a couple minor algae spots, so after a brush down/backwash i shocked the pool with 2 gallons of Hasa Sani-Clor. Jug...

I only checked FC, TA, and PH. Current Reading FC = 7 TA = 50 PH = 6.8 Previously FC = 7 TA = 110 PH = 7.6 CYA = 80 The plaster was chipped out and replaced with pebble back in May of this year. Any guidance to slowly raise the TA? I haven't had to do that before

Hello! About a week ago, my toddler tossed a battery powered toy gun into the pool, and the batteries ended up exploding overnight. It left our new pebble surface with a nice 12 inch rust stain. I called up the guy who resurfaced the pool, and he came by and somehow completely removed the...

I was thinking the same thing about residual dust from the storms... initially i was worried it may have been the DE getting back through the sand and into the pool. Is that possible?

My pool water started looking a bit cloudy about 3 days ago, and after testing the water, my PH looks spot on @ 7.5, however the FC was around 4, instead of my target of 7. We’ve had a number of big dust storms here in Phoenix over the past few weeks, so i also decided to backwash the filter...

After having our pool remodeled (13,000 gallon) and all new equipment/sand filter installed, I decided to take the bull by the horns and wanted to stop leaving my fate to Leslie's Pools! :D Here's what i came up with during my first test with the TF100 kit; FC = 4 CC = .5 TC= 4.5 CH = 525 TA =...
