- Please STOP adding Calcium Chloride to Salt Water pools.
It is really bad for the chlorinator and for your pool. Rarely does additional need to be added and if it does you need way less than most computer models will want you to add.

So how do u get calcium ok in saltwater pool?
nellcmbre A lot of pools don’t need any calcium added. It naturally rises with some pool surfaces. Water Balance is attained by satisfying the Langleir index. The calcium component can be offset with a slightly higher total alkalinity.
A salt chlorinator will simply take out excess calcium and deposit it into the cell. Self cleaning cells can then reverse polarity and dump these calcium flakes into the pool.
When it is required calcium carbonate is a better option.
Thank You, had salt water tested and told to add 64lbs of Calcium Chloride???? I've never been told that, glad I did some research. Thanks Again
How do you control ph with 150 alk and 150 calcium? Lets say a 15,000 gallon saltwater pool. Have to add over 40oz of acid weekly which in turn will drop alkalinity by 11-12ppm weekly. Monthly you would add 10lbs of bicarb to bring alkalinity back up. What are your thoughts on increasing calcium to lets say 350ppm and running lower alkalinity at 70ppm to control the ph ceiling and inturn use less chemicals to maintain LSI?
If you raise your calcium to 350 then you will get plating out on your Chlorinator cell.
Plus possible calcium issues elsewhere. A small dose of acid has very little affect on the total alkalinity.

Google ‘Langlier index’ if you want to research it further. Although adding a Chlorinator to the system does then mean it is good to keep the calcium lower.
I know what the saturation index is. I use it daily. I feel that Calcium hardness is the foundation to pool water chemistry. I would never tell anyone to keep calcium levels as low as you are suggesting!
New SW pebble finish pool, my calcium is really low (100)!! Ph is at 8. Added muriatic today, please advise on calcium?? Pool Builder advises it may ruin finish being so low? Pls help
There is a thing called the Langlier index and it is how water is balanced. To obtain balance you want the calcium and total alkalinity to total around 300. So a calcium of 100 and alkalinity of 200 will be balanced. But listen to the advice of the builder especially with a new surface.
If you do add calcium chloride just turn the Chlorinator right down or off for a few days
Hi! Had our water tested today and the calcium is at 66 - Alkalinity is at 112 which is in range for our 25K gallon pool. Should we add calcium? I was about to order it but then found your video!
Do you have a salt water Chlorinator? Watch the video I explain why that makes a difference. MRT
I have CH of 140 in a saltwater liner 20K-gallon pool. Need to increase it - do I add calcium carbonate? If so, how much? And where do I get it?
Hi Denise if your calcium is 140 in a salt pool that is enough. You do not need to add any more. To balance using the langlier index the total of your total alkalinity and calcium should be about 300. So run your alkalinity at 160 and you are good.
My pebble Tek finish there are hand fulls of pebbles every three months in the leave filter...pool store says ithe calcium level, 150, is too low...salt water pool help
So calcium nodules are formed by high calcium? Not by a bad plaster job?
It is normally about water chemistry. Bad water chemistry can draw calcium out of the plaster.
Mark's reviews and tutorials ok thanks. I thought was bad bonding from the gunite and plaster that has small hair line cracks, so the water is pulling calcium from the gunite through the plaster.
Hi, I added about 4 pounds of Calcium Carbonate to my salt water pool last night, and it turned cloudy (milky). Will the milky water disappear by itself? Or what should I do to clear the water out?
Mark how do you test the pool water to find out if you have too much calcium chloride in it as my pool liner has had it and needs replacing but over the years i noticed staining on the bottom of the pool and could never get it off and even the pool centre I went to back then said the stains were there to stay and didnt suggest anything otherwise so I want the pool to be spot on when i get that new liner early next year and I wont be adding any calcium chloride to it thats for sure.hope that all made sense.
So, what does it do to the human body if swimming in it regularly?
Calcium Chloride like Sodium chloride is a salt. It won't hurt you. Calcium is good for your bones and teeth
Mark...please help. What should the calcium level in my fiberglass saltwater pool be? Do i even need it? Currently it is 192ppm.
The best rough guide is that the total of your calcium and Total Alkalinity should be 300. So both at 150 is good. With your calcium at 200 then run your alkalinity at 100 or in a fiberglass pool even below that. But don’t add anymore calcium. MRT
@@Marksreviewsandtutorials Awesome...thanks so much for this.
What salt brand would you recommend? thank you
I don't understand this question sorry. Calcium salt? Sodium salt? Premium or Standard?
@@Marksreviewsandtutorials Sorry, i guess premium, so the salt will not discolor my vinal and quick dissolve... unless standard will do the job. Thank you so much for your input!
Gene Kutsovsky I would recommend the premium salt. That is what I use and sell. Yes it is ground finer and is also purified more leaving less impurities which can plate out on your cell.
Mark's reviews and tutorials what about brand of the salt you’d recommend?
Gene Kutsovsky I don’t think the brand matters. Just get what is labeled Premium
So in above ground pools like Intex that have saltwater generator u don’t need calcium?
nellcmbre A lot of the time the water you fill the pool with will have some calcium in it.
The liner surface doesn’t require any calcium. But some calcium ie above 40ppm will make it nicer on you eyes. But with a chlorinator you don’t have to take it over 💯 ppm and you certainly don’t use calcium chloride
So what should I use then?
have a question related to adding chemicals to an intex 18 x 52 round saltwater system pool. Is it necessary to add calcium hardness? Currently my hardness is at 0. What will happen if I just leave that alone and don't add in any hardness?
Tap water often has some calcium in it and some calcium is good to stop sore eyes, etc.
Tiled and Marblesheen pools also require some level to stop the water drawing the calcium from the surface. So with a salt pool I would say that the calcium doesn't need to be much more than say 100ppm. The Langlier index wants roughly 300ppm between the calcium level and the total Alkalinity so in Salt pools you can raise the Total Alkalinity to offset the lower calcium and still obtain perfect water balance.
In a salt pool adding calcium carbonate rather than calcium chloride is better and turn the salt cell off for a day when you add a dose of calcium.
@@Marksreviewsandtutorials ok thanks for responding. What will happen if I dont add any at all? Its currently at 11ppm.
@@jess4910 It won't harm a vinyl pool but can cause sore eyes. The langleir index component must be satisfied or it will be corrosive to metal parts, in pumps, etc.
Ok appreciate that. Can I add it directly to my pool undiluted and without prior mixing?
Jess Smith Read the label 🏷 for directions. But yes always pre dissolve Calcium as it generates heat as it dissolves.
