Pool Chemicals High Ph

how do i balance my pool chemicals?

my chlorine level is very high but my ph and alkanlinity are much below the normal range. my pool water is clear and clean. how do i bring the latter two levels up to where they need to be?

You need a few basic things to sort out your pool. Sounds like you already have a test kit for pH and chlorine so this is/was step 1. If chlorine is high, just stop adding any more until it is low again. pH and alkalinity are 2 different things but often confused. You can typically buy a number of chemicals at the pool store. First work out what you need to buy. If pH is low then you need some stuff often called “pH +”. Follow the instructions on the pack and dissolve the stuff first in a bucket of pool water if it is in crystals. Add half what you think you might need and keep the pool pump running for quite a few hours and check the pH again next day. Try not to overshoot but persevere to get pH right before anything else. If you do get too high then you may need some “pH -“. If you end up with algae or cloudy water then you may need algicide for former or flocculant for latter but dont buy unless you need. I had to add 2 litres of “pH+” to my pool this spring to bring it up to the correct 7.2. Dont worry about alkalinity because that strictly is a measure of something else and if the pH is right then you have a result you want.

High Total Alkalinity and Low Ph problem?

My TA was reading at 200 and my ph at 7.8. The pool shop told me to add acid to decrease my TA. I did this last night (16hrs ago) and let the pump run for 4 hours. This morning I have tested the water and the ph is down to 7.0 and the TA down to only 180. Do I need to give it longer to have affect on my TA? Should I be worried that my ph is so low? Have only just installed my pool this year, so am new to all this chemical stuff! Please help

Your ph at 7.0 right now isn’t an issue. It’s only a tad out of whack. That TA still needs to come down though. Where did you put that acid in the pool? You ought to have put it in the deep end and away from any skimmer or pool return and if you have a main drain suction, it should be off. That’s called “slugging”. The acid drops to the bottom of the hopper and changes your TA with little effect on your Ph.
On the flip side, putting acid in the shallow end or in front of a pool return will drop Ph and do next to nothing to your TA since the acid gets diluted right in front of the jet.
The time frame of 16 hours, if you added enough acid ( I wouldn’t have added more than 1 gallon at a time for a say, 16×32 pool) in the right place in the pool (deep end) would have dropped the TA to probably just above ideal at 130-140. Something you did wasn’t right. Either the dosage or the location. Why aren’t you running your pump for more than 4 hours per day? The equipment for any pool is sized that it has a turnover rate of 1.5. That means that in 24 hours, 1.5 times the pool volume gets filtered and sanitized. Less than 18 means that you’ll eventually have a water clarity issue since your turnover then is only 1 at 18 hours run.

Help my pool wont hold chlorine!?

My pool won’t hold chlorine. Here is the back story. Our pollen was tremendous and it sat in the pool for a long while. We finally got it out and we got our chemicals all worked out. But the pool has remained cloudy and we can’t hold chemicals. Just to be safe we put in Metal Free today…but to no avail it would seem. What can we do??? We are running out of ideas. Ok…here are the numbers

Free Chlorine .5 (this is after putting TONS of chlorine and being high on chlorine yesterday)
Total Chlorine .5
ph 7.4
Hardness 100ppm
Alkalinity 85 ppm
Cyanuric Acid 150ppm
Total Dissolved Solids 500ppm….

Please help. I need someone who really understands to respond. Getting desperate. It is a fiberglass pool with 12,400 gallons.

Numbers are ok except for the Cl. There must be organics still in the pool eating up what chlorine you add. That or you’re shocking during the day. Try shocking at dusk. You’ll get more bang for your buck since there are no UV rays from the sun knocking out your chlorine.
It’s organic load or a filter issue. One of the two or a combination of both.

Why does my pool need chlorine to much?

My pool seems the use of chlorine, as it should. I sat up in shock a bag Pool almost every day. Even then it is at the lower end of the recommended range. If I not, the pool will start to green after a day or two to make. I checked the pH value and it is always good – also took several samples Pool Shop – where a more detailed examination. They say the chemicals are good, except that chlorine is low. How much chlorine do with a pool (15,000 gallons pool)?

try to put chlorine in your pool bars … they can go in the baskets and baskets of swimmers in swimming on the water …. it might help. Do you have a Polaris suction thing? These allow algae and dirt. All pools must be at 1.5 ppm chlorine, shocking as it should bring up to 3.0 ppm chlorine ….

Pool Care – Keep your pool and have to remove lime scale and algae?

How do you remove stains of algae from the pool after it is empty? I called the pool company and they told me to apply again & off spot after full pool. Is there a cheaper way to go from household cleaners? In addition, it is a good way to remove calcium mosaic? I have a plaster pool on the question of whether to fiberglass or vinyl-response.

We leave the swimming pool on the Spring and scrubbing tiles and plaster – is hard work, but ultimately fluffy. We use packets of powdered Power More Leslie to save pool and get a bucket and brooms and gloves and go to town. We have seen amazing 20,000 gallons pool after a weekend of work! Fit music and have fun – you swim in a very short Time!
