This is a chemical reaction between the acid and the mineral.
Try pouring some straight muriatic acid over them.
Pouring hydrochloric acid, or HCL, over a mineral will cause carbonate minerals to effervesce. This application is called the "acid test," it simply examines the mineral or rocks reaction to acid. Calcite is the most commonly found carbonate mineral and it will fizz during the acid test. Dolomite is another carbonate mineral; however, it will only fizz if it is first powdered. Experiments also show that undiluted vinegar can cause effervescing, but it produces less vivacious results. Some sedimentary rocks that fizz include chalk, coquina, oolic limestone, fossilferous limestone, and micrite. The metamorphic rock marble also fizzes.
I'm assuming you want the phrase "pouring in" and not just the word "pouring." Rain is pouring in through the hole in the roof. Whenever she takes over a company, money just starts pouring in.

pouring lemon juice all over your terrace :P
Rub a finger over the mineral
Pouring slat over a fire does not stop it unless the quantity of salt used is enough to cover the source of fuel. While salt will not itself burn, there is no intrinsic property of salt that suppresses fire.
Very carefully. Follow the manufacturers directions. I am guessing you are cleaning calcium deposits on a DE filter. I would assume that you would dilute the acid with clean water (pouring the acid slowly into the water and not water into acid) and pour enough to cover all of the grids. Then soak over night.
Naturally formed acids can weather rocks. When water reacts with carbon dioxcide in the air or soil, a weak acid, called Carbonic acid, forms. Carbonic acid reacts wih minerals such as calcite, which is the main mineral that makes up limestone. This reaction causes he calcite to dissolve. Over many thousands of years, carbonic acid has weathered so much limestone that caves have formed. Chemical weathering also occurs when naturally formed acids come in contact with other rocks. Over a long period of time, the mineral feldspar, which is found in granit, some types of sandstone, and other rocks, is broken down into clay mineral called KAILINITE. Kaolinite clay is common in some soils. Clay is an end product of weathering.
By spelling the word into helen's hands while pouring water over them.
it's WATERFALL :)
