How Much Chlorine Do I Need For My Pool

by Pauline
(Jamaica)

I am new at this. I have an above ground pool Intex 24/12 but I am not sure how much chlorine to add.


I am bothered by Algae. Can you help?




Thanks for the question Pauline

I have received this question several times so I'll start with some links you can look over:

Correct Levels For Vinyl Inground Pool Using Chlorine

Knowing What Chemicals To Add & How

The amount of chlorine you'll use depends on some factors such as size of the pool, usage, splash out and topping off, evaporation, other chemical readings, rain, etc...

I figure you have an 8,000 gallons pool. An educated guess would be about 1 gallon per week but this would be the best case scenario. Without know the details it's a little more difficult to give you a better approximation.

You need to get a good test kit such as the Taylor K-2006. I've made several videos on YouTube on how to use it. Concerning the algae issue, I'll need to have your current and complete chemical readings, the actual numbers:

Chlorine, CYA (cyanuric acid/stabilizer), pH, Alkalinity, Calcium Hardness, and Metals (iron and copper) and names of any algaecides you may have used along with clarifiers, phosphate removers, and/or flocs. It makes troubleshooting much easier and the process of clearing up your pool will go much faster.

It would be very time prohibitive for me to go through each and every detail of how to take care of a pool. It's fairly easy but each pool and situation is different. My site has been up since 2008 and has over 1200 pages. Condensing that down would take considerable time and effort.

Liquid Chlorine?

by Crystal
(Globe, AZ)

Your you tube pod casts are very insightful. My question to you is, Does it matter if I use different brands of chlorine?

Like a store brand liquid chlorine, and HTH brand chlorine tablets? Please help! I have a 7,605 gallon above ground pool. It is 23ft long by 13ft wide and 3 ft deep.




Thanks for the question Crystal

The best thing you can do to have a great pool is to become educated. Gather as much information as you can, learn what to look for, get the right mindset, and take control of your pool.

All liquid chlorine is sodium hypochlorite. Some brands have more than others. Pinch A Penny sells their chlorine at 10.5% sodium hypo 2.5 gallons for about $5.25 while Leslie's is the same % and sells for $3.99 per gallon. In In Swim has liquid at 12.5%. You can also use unscented grocery store bleach. It's the same as pool chlorine but 1/2 strength. It sells for about $3.59 a gallon. Your best bet is to use liquid pool chlorine especially in AZ. My pool route was in Phoenix/Mesa/Tempe and I know how hard the water is. Never use calcium hypo as this will raise the hardness of the water.

My advice would be to shop around to get the best price and % of sodium hypo. Many stores have you put a deposit on the container then simply swap them out when you need more. I like this method as the jugs are used over and over again and in the long run is cheaper than bleach. Some places don't recycle so you use the bleach jug once then throw it away. You also need to use twice as much as already mentioned. Very wasteful.

The chlorine tabs are this necessary evil. You can use them to keep a constant stream of chlorine in the pool, but, it adds stabilizer (CYA) to the pool. The range for CYA is 30 - 50ppm. Once it starts getting into the 70 - 80ppm range it's time to do a partial drain and refill.

I'd stay clear of HTH 3 in 1 tabs. They have extra calcium and salt. The 3-1 tabs are faily new so I don't have recent personal experience with them but I recommend against using any multi-purpose product because the ratio of the different ingredients are almost never the ratio you actually want.

These kinds of tabs should never be used in a chlorinator that has ever had Trichlor tablets because there may be an explosion. Stick with tabs that contain TRICHLORO-S-TRIAZINETRIONE.

Never mix chemicals and never pour chlorine directly into the skimmer. Broadcast it around the pool, sweep and FILTER.

Bottom line is this. Use liquid chlorine at the highest possible % of sodium hypo at the lowest price and use Trichlor tabs. Never put tabs in the skimmer. Use a tab floater. Keep the chlorine level at 2 - 4ppm and CYA at 30 - 50ppm.

I hope this has answered your question to your satisfaction.
