testing

Hi everyone, Long story short I've inherited my first pool (new house purchase), have read through TFP Pool School articles, purchased the Clear Choice Labs Total Salt Water Pool Test Kit (nearest Australian equivalent to the TF-100), and got excited for my first testing session. Well I've...

Hi all, I first started here last year trying to get my pool right. I was not able to buy a test kit until now (I got the TF Pro Salt) and it showed up yesterday and I just finished testing. Here are my levels: pH + Chlorine Testing block - Cl - 5+ | Br - 10+ | pH - 8.2+ (see photo) FC - 7.5 CC...

I am a chemist and have been able to get my hands on one of these if I wanted. I know a lot of pool stores use one of these 2 or something similar, while I don't trust pool stores themselves the tech seems to make sense. It would seem to be a spectrometer that reads in the visible light range to...

Hi- I searched for this but didn’t see an answer. After 4 months ago taking over care of my SWG pool from my pool service, I’m trying to learn all I can. Pool/attached spa/hot tub is ~7-8yo. Installed by prior owner and was a chlorine (I’m assuming- it definitely wasn’t a SWG) pool. When I...

Hi everyone, I have a brand new SWG pool, 13,500 gallons. First week, pool company tossed 3 bags of salt in. 1st Water Test: At home, SWG measured salinity at 3100ppm BioGuard test - recommended adding 101 lbs of salt (salinity 2500), 2.75 lbs of pH Adjustment, 5.5lbs of Stabilizer 100, 10.75...

If, like me, you enjoy using a speed stir, you might also enjoy using a giant pipette to get your 10ml samples. Beats bending over to stare at your test tube, then trying to remember whether meniscus goes up, down, or even happens on plastic. Plastic from which the scale is coming off anyway...

Second season pool novice. 24' round above - ground. Should I trust the water testing and ensuing product advice of my local pool stores? Or is it possible the have me chasing my tail, real slick like?

First off - I researched for the answer but could not find what I needed. Sorry if I missed it. Point of Confusion: If I follow the FC/CYA chart and I keep 30-50ppm CYA levels, my FC needs to be >5ppm, however the T1000 test kit instructions, and various forum posts and guides, state that the...

I just purchased a Coleman 26x12x52 pool. Just wondering if I should put chlorine in while the pool is filling or wait till it is full? Also wondering if I should test the water before doing anything and how many tablets should I start with?

I test on my own but I do like to get a test from other locations to compare my yearly test kit and see if they're close. I brought some water to Leslie's just to get what they think my levels are at and compare and that brings me to my question. On the paper they have Free Chlorine (Ideal...

Hi Everyone! Our pool is almost done which means I’m starting to research how to take care of it…this site has been great! The consensus I’m seeing is: stay away from strips and get the TF-100. Am I correct in my assumption? If I go the TF-100 route, how much are you spending in a year for...

I'm on the HOA board of a condo complex with 200+ units. We have an outdoor pool and an indoor hot tub. We're taking a closer look at water testing, and though our pool traffic is not what I would consider "high volume" (we're not the YMCA; I'm guessing we have a total of about three dozen...

My CC tested 0.6 on a FAS-DPD test using a 25mL sample. If I understand correctly, the recommended approach to reducing CC when greater than 0.5 is to shock to 12ppm FC. I'm not sure if this is technically SLAM, but assuming I need to maintain 12ppm FC (or whatever the CYA/FC table specifies)...

Fall-time here in Northern California means lots of rain. So far, it's been raining all weekend (several inches gained). The pool is full, but we have a drainage channel/grate built into our concrete along the pool, so I'm not worried about bringing the level down yet. We also have a drain hole...

This page says to glance and not look for the black dot, but this page says to continue pouring until "all traces of the black dot at the bottom of the view tube completely disappears, even after you stare at it for several seconds." Which one is right?

Hello TFP members, I recently took over an 11500g saltwater pool, which is 1.5 years old and has less than subpar parameters (I mean almost zero for everything but NaCl, Ca, Alk, TA and TDS @5000 with pH well over 8). Today, I already maintain several marine reef aquariums and after many years...

Hi, We are new to the pool game having just moved to a house with a pool... Left for us was a Scuba II Electronic pool tester, that measures Chlorine in mg/l (0.1 to 6.0) and all other measurements in mg/l as well apart from pH obviously.... How does that relate to the logging units of the...

After I add the R-0871, and the water becomes clear, I have noticed that - if the water is left in the vile - after a minute or two the water will once again return to pink. Is that normal? Or does that mean that I am doing something wrong? I’m using the TFP test kit and the Taylor speedstir...

We just got our pool filled With water 6 weeks ago... Its brand new pebble sheen gunite pool which the spa is flush attached. The pool builder gave us the pentair kit and all equipment is Jandy. Its Jandy aquapure 1400 and the pool is just under 24000gallons. We purchased a Taylor salt kit in...

Pool test results from this morning: Free Chlorine: 28 pH: 7.0 Total Alkalinity: 80 Calcium Hardness: 430 CYA: 200 Water Temp: 85° (Taylor K-2006 test kit) Pool specs: Orlando, Florida 10,000 gal in-ground Plaster Chlorine Variable Speed Pump with pressure gauge My pool calculator reports the...

Hello, all. After years of paying a pool guy $100/mo my sister has asked me to take over (the maintenance, not the paying). I've replaced the booster pump and the majority of the parts in her Pentair CC200 and everything still works so I got that going for me, which is good. Bought a K-2006...

The background: For reasons that have not yet been determined, the output of my SWG failed and the FC went to 0 sometime during the week. The obvious surprise consequence was a cloudy pool the following weekend, so I hit the turbo boost on the cell and tossed in about a pound of dichlor that's...

Since I replaced my pool water a few weeks ago and finally bought a Taylor K2006A test kit, I've been testing every day. I don't always to CH or CYA, but I always do FC, CC, PH, TA. Is that excessive or normal? Wondering what others do....

I've looked around this forum for a while, but this is my first post. The pool runs on bromine. The sun breaks down the bromine rapidly, so this morning I put 2 trichlor tablets in the chlorinator to try to use less chlorine bleach. My understanding is the chlorine activates the bromide. This...
