I was recently at the fish store and the salesman said that the reason for the high alkalinity in my tank was due to shells made of calcium. Why would Calcium be making my water more basic?

# The shells aren't made of calcium, they're made of calcium carbonate. # Calcium carbonate is the salt of a strong base and a weak acid, and is therefore weakly alkaline. I understand that you can make CaCO3 by the following process: HCO3 + CaOH => CaCO3 +H2O But once you have made CaCO3 ( a slightly alkaline salt) from the acid and base, what is happening to the CaCO3 in the H2O that is making the water more basic? In other words, how can CaCO3 have anything to do with the lone OH- ions present in the water?

How is calcium precipitated?
Calcium and carbonate (a component of alkalinity) can precipitate from the water column if the product of the concentration of each of them rises too high.
How exactly do calcium reactors work?
A calcium reactor maintains the level of calcium and alkalinity inside the reef aquarium. The reactor itself is nothing more than a chamber, it holds some sort of calcium-based substrate which is insoluble at 7.9-8.3 water pH. However, the substrate dissolves in lower pH, which frees the calcium and alkaline ions.
What does the mean of m alkalinity and p alkalinity water?
1. M-Alkalinity (also known as Total Alkalinity) measures the amount of carbonate, bicarbonate and hydroxide present in terms of "ppm as calcium carbonate". ( M-Alkalinity measurement is based on a sulphuric acid titration using a Methyl orange indicator that goes from yellow at a pH of 4.5 to orange at pH of 4.4 at the endpoint.) 2. P-Alkalinity measures the amount of carbonate and hydroxyl alkalinity present in terms of "ppm as calcium carbonate". P-alkalinity is measured down to a pH of 8.3. The M-alkalinity is measured down to a pH of 4.3.
Are the stalagtite-looking calcium build-ups on the walls of the pool due to not enough calcium or too much calcium in the water?
The following factors combined determine whether water is 'corrosive' (etching of plaster) or 'scale forming' (nodules, scale on walls). pH, Total Alkalinity, calcium hardness, TDS (totally dissolved solids) and water temperature. These items are a result of improper water balance. One could generalize and say that there is too much calcium in the pool/spa. However it is possible that the calcium level is ok and the pH or total alkalinity is out of balance with the same result. The water must be balanced and this requires monitoring and controlling the following items: pH, total alkalinity, calcium harness, total dissolved solids and temperature. Once we have all of these test kit reading then we can perform a calculation to see where the water is currently at and what adjustments are needed to get the water balance corrected.
If you recently found a flaky white substance in your saltwater pool and you have a cartridge filter what could this be?
Are these loose flakes? Could be calcium deposits if attached to pool walls etc. Are you adding proper amounts of muriatic acid? Are you testing your pH? Alkalinity?
What mineral is calcium?
Calcium is calcium-it is its own nutrient.
What are the elements present in calcium hydrogen sulphate?
the 3 elements found in calcium sulfate are calcium,sulfur and oxygen
The most common mineral in the body is?
Diamond No its calcium.
Are calcium carbonate and calcium citrate ionic forms of calcium?
Yes, they are calcium salts.
What is the name of the chemical formula CaS?
Ca is the periodic symbol for Calcium. S is the periodic symbol for Sulfur. As such, CaS2 is a compound of calcium and sulfur.
How much baking soda to soften pool water?
Baking soda will not soften (remove calcium hardness) from pool water. It will raise total alkalinity.
Is calcium in salt?
Sodium chloride doesn't contain calcium. Calcium chloride contain calcium.
