SMOOTH ACID ETCH Definition This finish is achieved by casting concrete against a smooth hard surface. After removal from the form the element is allowed to harden to a uniform hardness. The product is then washed with an acid solution and scrubbed to remove the cement surface to a sand surface level. The result is a smooth sand textured surface.
The muriatic acid wash (after the concrete has cured) was to get a nice finish by removing any leftover slurry, as I understand it. Then sealing to protect the finish. I think I used Thompson's water seal before on a new driveway and wasn't too impressed.

Acid washing the cooling system in a marine engine. Ah, salt is sodium chloride and muriatic acid, ie. Hydrochloric, is HCl. Hence I don't think that it would work too well for you. Use sulphuric. But for clean water it should be OK. Use 50% concentration...but then if you buy muriatic it is probably diluted somewhat anyhow. Run for an hour, ie.

Filter media. The filter media is the important component of the water treatments filter which actually removes the particles from the water being treated. Water Treatment filter media is most commonly sand, though other types of media can be used, usually in combination with sand.
Acid Stains produce unusual and permanent color effects in concrete, selfleveling topping systems, gunite, cement plaster, stucco, shotcrete, natural stone marble, cultured stone, limestone and other surfaces. Each concrete acid stain creates uneven color effects that simulate the natural shadings and aged appearance of stone or masonry.
