chlorine

Does anyone have any good leads on where in the DFW area to find liquid chlorine during the coming fall and winter? Walmart has pulled all of its supplies, and Lowes and HomeDepot are asking $2.30 more per gallon than Walmart, even in volume.

I've been stuck for the past couple of days trying to figure this out. I use a proper test kit to test levels and all other levels check out. I also use my local pool shop to test when my CYA drops below 30 since this can't be tested in the liquid Taylor kit that I use (if I assume 0, then I...

I wanted to bump up my calcium by about 80 or 100 ppm. I did so late at night, several hours after topping off the chlorine to 6 ppm. In the morning the FC was essentially 0 ppm. I added enough liquid chlorine to bring it back up to 6 ppm, then a few hours later it was around 1 ppm. Finally...

We just signed the paperwork for a build. We are just north of Houston Texas. We are in the process of picking all the items out. We started with salt as the direction we wanted to go in, however, we were talked out of it due to the jump rocks we are getting installed. As we go through and pick...

So I went on vacation and I assume within a couple of days of returning my flow sensor got chewed through. Chlorine was at .05. No green or visible algae, but I'm sure it's there. I repaired it and set it to super chlorinate until I could pick up some liquid chlorine (sodium hypochlorite 12.5%)...

First off sorry if this is a dumb thread I decided to join because I would love some advice… This is my first year with above ground pool 4000 gallons maybe, Steel Pro Max 15 x 42 pool for my son and I am being tested by the pool God’s! My test strips are showing same results almost always...

I never got an answer from Taylor about that one fluky series of FAS-DPD FC tests I encountered back in March. It is now the only chlorine test I do unless I am demonstrating the straight-up DPD method to one of my lifeguards. I love having a confidence level in my results give or take 0.2...

Hello everyone! I've been reading this forum for a while now and have learned a lot of great information, though I'm having a problem that I cannot seem to find an exact answer to. TL;DR: History I have a rectangular in-ground pool about 3 years old, approximately 18,000 gallons. This was...

I've changed nothing about my process except for the time of day I just tested. Normally I see about 4 or 5ppm left every 3rd day. Today I tested on a 95F degree day at 2pm on a day with full sun and my chlorine is reading 30+ppm! My testing kit is reliable, it's a FAS-DPD test that has never...

*EDITED* Greetings, Need some encouragement/help...keep shocking or SLAM? My kids are going to make me walk the plank soon... Note on pictures: Pictures are chronological; Picture 3 is at dark dusk; Lots of seedling/leaf debris that gets cleared 2X day 3X vac to waste 2X cartridge rinse...

I've been using Taylor's testkit for years and when checking FC before converting to a SWG pool the color would change quickly to pink to indicate chlorine. However, I just converted to a SWG and noticed that using the Taylor DPD reagent (R-0870) doesn't turn pink as quickly as it did before it...

Hey Team, Got (this) linked through regular spam aka "You bought one thing from us once so we presume this to mean you wanna hear from us 12 times a day for the rest of your life," email from a local pool supply store. I read it because I have a full Stenner pump setup I am quite happy with...

Hey all - I just wanted to come here for a little more information from the community that I haven't been successful finding on my own. I've read that chlorine starts to break down relatively quickly on the shelf, and will be less effective over even a few months on the shelf. My main...

We have an above ground metal frame pool. 12 feet by 33 inches. Just under 2,000 gallons... Steps we followed: 1. We put the pool up. 2. The fire department filled the pool up. 3. Very dark and dirty water. 4. Shocked the pool and have the floating device with chlorine tablet and the arm and...

I opened my pool roughly 2 weeks ago. I expected a green mess down there, but instead I found a detritus mess down there with zero green. Upon testing, I found FC 14 in the water. According to Pool Math, it's supposed to be between 4 and 11 , so that's not too far beyond the pale except I...

Apparently chloramine is used as our tap water disinfectant. Our water doesn't have much of a smell at all to it. Our city is doing maintenance that requires switching to free chlorine to perform a Chlorine Burn and said that the water will have a strong chlorine odor (see artlicle below)...

Is it possible to buy liquid chlorine on the Internet (with taxes, shipping & exchange to and from your home pool) in normal residential quantities? There are two main threads discussing the current high price of liquid chlorine which prompted this specific question about shipping. Forums...

Hello, I know this is a silly question, but I've searched up and down and just want to be sure I have my info straight. With the simple PH & Chlorine test kits that you can buy from Walmart that are Chlorox brand, is the Chlorine test testing TOTAL CHLORINE, or is it testing Active Chlorine...

Hello — I shocked my pool last night around 8pm, added 56% cal hypo and some bleach, enough to bring the FC levels to 20 to 30ppm (getting rid of black algae). Brushed the pool good that evening twice. At 7am the next day (11 hours later), checked the FC levels twice taking samples from 2...

Hi all. My pool has been rock solid until very recently. All levels are pretty spot on, but all of a sudden the water is causing eye irritation. I can't figure out what it is. One person suggested that the non-chlorine oxidizing shock I use might be causing it because some people can be...

My pool was completed about 30 days ago. After plaster pool was acid washed and then filled but I didn’t had sod installed at the time and Texas Red Dirt Top soil got in the pool in large amounts. Per PB instruction, I brushed about 5 times a day towards center drain and got lots of the dirt...

Hi all. For weeks now I've been yo-yoing back and forth between lowering my chlorine, adding chemicals to treat metal staining on entire surface of my pool and then once clear adding chlorine back in and then watching the staining come back. What's more is that in treating the metal staining my...

I have a gunite pool around 45,000 gallons. My CH was sitting around 225-240 for a week or so. I added around 40 lbs of calcium chloride. Chlorine was at a 6 (CYA 50). This was tested & added when the sun was setting. The next morning chlorine was completely gone. This has also happened once...

Using a salt chlorine generator results in the generation of chlorine as well as sodium hydroxide (a strong base) that increases PH. Therefore, if I increase the chlorine generation % of my device, I will also be increasing PH. 2NaCl + 2H2O → 2NaOH + Cl2 + H2 OR Sodium Chloride + Water =...

My buddy tipped me off to Walmart selling 128oz of 10% sodium hypo for $4.89/ea. I'm able to get free next day shipping with orders over $35. https://www.walmart.com/ip/seort/48938023 Seems like a no brainer unless someone has a better hook up? I have vinyl so cal hypo is an option but this...

New salt water generator pool. All pentair products. Been trying to maintain it for about 2 weeks now. really struggling with keeping chlorine levels up. The past 2 weeks I have had basically zero chlorine. Last week I identified no chlorine , as well as cya at 30 and high pH. I added acid and...

We have a new 20,000 gallon SWG Gunite Pool filled on 5/6 and the pump running continuously since then, mostly at low speed (1500-1700 rpm) when not in use or while cleaning. 18 bags (@ 40 lbs each) of salt was added on 5/27 which works out to about 3400 ppm. The Intellichlor IC40 label says 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?

Hi, I want to give a quick background on my situation here. Last week we got algae outbreak with high CYA, drained the water, and managed to bring down CYA to 50. I have followed the SLAM process and thankfully I have never seen my water being this crystal blue clear since we have the pool...

Hi Everyone - I have some questions about pool opening and pool covers. I have an old loop-loc cover that probably is in need of replacement. Each spring, I spend about a week sanitizing the water in my 43k gallon pool. When I remove the cover, the water is black – it’s disgusting. It entails a...
