What else can I help you with?
You notice that there are deposits of calcium carbonate along the inside walls of the kiddie pool. What type of reaction caused this?
The deposits of calcium carbonate are due to a chemical reaction called precipitation. When the water in the kiddie pool evaporates, it leaves behind calcium carbonate, which is not soluble in water and forms solid deposits.
Is the pH of a pool drops below 7.0 calcium deposits will buildup which may may scale of the plumbing the tiles and the pool finish?
Yes, when the pH of a pool drops below 7.0, it becomes more acidic, causing calcium carbonate to precipitate out of the water and form deposits on the pool surfaces. These deposits can lead to scaling on the plumbing, tiles, and pool finish, which can be difficult to remove and may damage the pool over time. Regular monitoring and adjustment of the pool's pH levels is important to prevent this issue.
What else is in common with calcium carbonate and hydrochloric acid?
Calcium carbonate and hydrochloric acid react to form calcium chloride, carbon dioxide gas, and water. Both substances are commonly used in chemistry experiments and have important industrial applications. Additionally, they are both found in nature: calcium carbonate is a common mineral in rocks and shells, while hydrochloric acid is found in the stomach to aid in digestion.
What is reaction of calcium hypochlorite and sodium bicarbonate?
When calcium hypochlorite and sodium bicarbonate react, they produce calcium carbonate, sodium chloride, and water. This reaction is commonly used in swimming pool chlorination systems to release chlorine gas for disinfection purposes.
What if you used water softener in your salt water pool?
Filling a plaster pool with water from a salt type softener will severely damage the plaster. Salt water softeners exchange salt for calcium and leave the water in a calcium deficiency. Seeking its dynamic balance the water will leech calcium from the plaster to satisfy its need for calcium making the plaster etched and rough. Adding salt to regular tap water is not the same as filling with soft water as the calcium is still present in the tap water. 180 ppm of calcium is considered the minimum and low calcium can be raised by adding calcium chloride.
What does it mean when calcium hardness is low in a pool?
Low Calcium Hardness in pool water means that there is low calcium in the water and is considered "soft" and soft water tends to be corrosive. It will etch away and your plaster and any metal object the pool water touches.
How do you raise pool calcium?
To raise calcium in your pool use calcium chloride. You premix it in a container to let it dissolve and add 6lb for 10pmm in a 50,000g pool.
What to do with high pH in pool?
If memory serves me correctly, high PH is lowered with Calcium Carbonate. You probably want to consult someone who is licensed in pool care, however.
Should you tie the pool water leveler to the water softener?
You can, if the water presently in the pool is 'hard' - but be very careful to keep an eye on the Calcium Hardness of the pool water. If you filled a pool with water from the softener, the water would be hungry for calcium and drag it out of the pool walls, making them feel and look like sandpaper. Calcium hardness should be kept within 200-275ppm. best to use regular water for topup and keep the pool water properly balanced (see your local pool store).
What does buffer and added hardness do for a saltwater pool?
Buffer and added hardness do the same thing in a salt water pool as in a fresh water pool. The buffer (sodium bicarbonate aka bicarbonate of soda) stabilizes the pH of your pool so that addition of acid or base doesn't change the pH very much. The hardness, mostly Calcium, helps achieve water balance to make the pool neither deposit (precipitate) excess Calcium Carbonate to your pool surfaces nor corrode (remove) Calcium from your plaster pool surface. The combination of pH, Total Alkalinity (adjusted for Cyanuric Acid), Calcium Hardness, temperature and Total Dissolved Solids determines whether your water is balanced. Just keep these values near their recommended amounts for your pool and you should be fine. If you're a techie and want the full formulas, do a Google search for "Langelier Saturation Index".
What is the best way to lower the calcium hardness in the water in the pool and the water used to fill it?
The best way to lower calcium hardness in the pool water is to drain the water and refill with water of lower calcium hardness. Have the calcium hardness tested for both the pool water and fill water. Ideal range is 175-300ppm. There are 'calcium reducer' products available through pool stores, but not sure how effective or economical they are.
Is soft water from a home softener system ok to feed the pool auto leveler?
I would only connect the soft water to the auto-fill if you are having a problem with the pool water being 'too hard'. If you do not have hard water in the pool, there is no advantage in using soft-water for topup. You can use the soft water BUT you MUST maintain the correct level of calcium hardness in the pool water (200-275ppm is good). If the calcium hardness falls too low other problems can occur, including damage to plaster walls.
