chlorine

It's possible This Thread belongs under the chemistry area, as it's my first post it's here. I opened my pool a week and a half ago, and when I did, the pump motor was gone. I've had some issues with the previous pump and so I made the decision to pull the trigger on a pump motor combo. While I...

Obtained a house with a 24 ft round above ground pool mid-July last year. They previous owners used baquacil products and it was a pain all summer to maintain and very expensive. I plan to convert to chlorine when we open in a week or two (we are in NW Indiana). Wish me luck!

Hi everyone, I’m new here and thrilled to be joining Trouble Free Pool! I recently bought my first home in Jarrettsville, Maryland. This is my first time owning a house—let alone one with a pool—so I have a lot to learn. The pool is in-ground and chlorine-based, and there are lots of trees...

I finally switched to SWG so I am donating my chlorine tablets to a friend. I currently have the chlorine tabs individually wrapped in their original buckets in a plastic deck box. I want to take the chlorine out, and store bottles of muriatic acid in the box instead. Knowing the two should...

The post title says it all. I am a new pool owner. We have an 18' x 52" above-ground pool, roughly 8300 gallons. The pool math app has suggested very low amounts of my 12.5% liquid chlorine to raise my FC. I ended up adding 256 oz of the liquid chlorine and the FC level is still 0. My CYA level...

Long time lurker, first time poster, be gentle :) The chlorine in my pool keeps dropping down to 0 after installing two different brand new chlorinators. Tried everything, including pre-emptive phosphate starver treatement. Help... :( Historically used vintage metal box Kchlor AC20 non-self...

I came across HTH Super Shock at Costco. They’re granules but cal hypo and don’t contain CYA. Are those safe to use or does anyone have any experience with it?

I'm considering getting a Rola-Chem tank and peristaltic pump for liquid chlorine to mitigate the CYA buildup issues with tabs. I know the line from the rola-chem should be plumbed in the pool return line past the heater. Obviously with this setup I would predominantly be just using liquid...

Pool temp is around 50 °F these days SWG has not operating due to low temperature Measured pH at 7.6 CYA is between 60 and 70 Chlorine drop test was completely clear I clean the pool of any leaves the skimmer doesn't catch once a week. There is no visible algae. Given that the chlorine drop...

G’day folks. Simple question: Chlorine or bromine in your hot tub? And why do you use the chemical you do? Steve

Hi all, My chlorine level seems to have drastically dropped within the last couple of days. I’d love some advice as to what might have happened. For the last 2 years, I’ve been using liquid chlorine and have been keeping my CYA level around 40/45. Generally, I’m at a FC 5 or 6 every day. Two...

Hello everyone, New house/pool owner here since August and I'm having a hard time understanding the different chlorine results I'm getting which causes me to doubt my ability to take care of the pool myself. My issue is that I don't know who and what to trust or at least how to understand the...

Good morning all. Seems like I'm constantly fighting to keep my pH in the desired 7.4-7.6 range and alk 80-120 in my 15,000 gal, pebble tech pool. You guys already know this....adding muriatic reduces pH but it also reduces the alk. Adding baking soda raises the alk but also raises my pH...

New pool owners, so I’m sure we messed up along the way, but let me tell you the series of events to get us where we are today: * Low salt pool ~ 75000L in ground w/ liner 1. Did weekly at home tests (levels more or less seemed fine) 2. Took water in for pool store testing every few weeks and...

Hi all - I just discovered TFP today after being frustrated with pool stores/companies over the last year. I moved into my house with a pool in late 2022, so this is my second season with it and it has been a struggle keeping it maintained. It seems that no matter what I do, I get algae buildup...

I've been having issues keeping the chlorine in the pool ever since the water has been reset after 1.5yr of stagnant water and I've never quite experienced this unless I'm not measuring things right. In the past, I used to add less than half a gallon of liquid 10% chlorine daily and that used...

A week ago I noticed a little bit of algae starting to grow in the corner of our tanning ledge. Then I noticed that my SWG at 100% was not keeping up with the chlorine demands and was constantly 2ppm or less. Once I brushed the algae off it hasn’t returned. Also CC has never been higher than 0.5...

Hi guys, I'm a little at a loss of what to do! We got a 12x30" pool for the kids to keep them cool this summer and they've gotten to swim a grand total of one time because I cannot seem to get the levels right. :cautious: I bought test strips (which, after poking around this site, seems to...

Hello, I am brand new to the world of pools! This March we started off the season with upgrading our sand filter, draining the pool, giving it a nice bleach bath then refilling. Since then, it has been a hassle keeping it swimmable. We have a great guy who tends to it weekly but we cannot...

We had an issue with high CC (above 2), so we began the SLAM process Monday morning using FAS-DPD test. We have gotten the CC under control, but our FC has only gotten above 1 on one test. We are adding 60-70 ounces of 12.5% liquid chlorine every few hours based on Pool Math calculations and...

I added over 120 drops of R-0871 into my Chlorine Drop Test, but the solution still won’t clear up. It remains cloudy, and I'm worried I might be misusing the test kit or will run out of R-0871 before getting clear results! Despite following the instructions and trying different samples, I'm...

I have a new to me 19000 Gallon pool. The previous owner used pool rx minerals with a hacked frog ease system using 3in chlorine tablets. My CYA levels is around 100 and my Chlorine is at 1. I took out the pool rx and now I want to get chlorine levels in check. I believe the best solution is to...

First time pool owner and I am having trouble with Algae but not overly bad. It appears on the steps and sides of my 15,000 gal pool. It is in full sun majority of the day and I live in a desert-like climate. We are above 100F these past 2 weeks. I seem to be getting a lot of evaporation from...

Hello, I'm getting an in ground hot tub put in next year and, after reading up on recommended maintenance I have a question: If I have planned heavy use of the hot tub, get the FC up to a good starting level, but see that with people in the tub, and the tub cranked up the FC drop to the point...

Bottom line up front : what can cause a freshwater pool to slow falsey high free chlorine readings? I’ve had my 14k gallon in ground pool for about 4 years now. It has an automatic chlorine feeder. For the last 6 to 9 months I've had this issue where my chlorine is constantly showing higher...

Hello all! I'm a brand new pool owner rookie! We bought a house in March and opened our pool a couple weeks ago and still learning EVERY.THING. We want to learn how to maintain and care for the pool ourselves as we've already been put off by a couple local pool companies. I've been trying to...

Hi all, I have an in-line chlorinator (no salt) (CMP power clean ultra). I added more tabs than usual to the chlorinator without reducing the flow rate which made the free chlorine rise too high (rookie mistake!). I turned off the chlorinator by rotating the flow rate dial counter-clockwise as...

Now that it's starting to get warmer here in San Antonio, our pool is just DRINKING bleach like crazy, and I'm wondering if that's normal or I should be supplementing for chlorine levels? Our pool techs that we fired in the past just added the same stuff every week without measuring levels and...

Update: I started following the SLAM method. Have used almost 9L liquid chlorine in 5.5 hours. Does this sound crazy ? 11am free chlorine @ 0. Added 2.8L liquid chlorine and got it >10. 2.30pm free chlorine @ 0, added 3L liquid chlorine. 3.30pm free chlorine @ 8. 4.30pm free chlorine @ 0...

Hello everyone, I just purchased a new home. It has a 17,000 gallon indoor, inground, geothermal heated pool. It’s 14 years old, original vinyl liner and all original pool equipment. It wasn’t used much by the previous owners, but was maintained by the local pool company who built it when new...
