1 GALLON JAR NU-WELL 100 PELLITIZED ACID.

Nu-Well 100 pelletized acid is formulated for pouring directly into the well. While it may be dissolved and pumped into the well as a liquid, the pellet form rapidly falls through the water column, providing concentrated acid cleaning power at the bottom of the well. The sinking pellets are ideal for wells with short to moderate lengths of screen at the bottom. Agitation of the acid into the blocked area will greatly enhance cleaning. The acid solution should remain in contact for a period of 12 to 24 hours, depending on the nature of the blockage. The table provides recommended dosages for general well cleaning. The amount of acid consumed will depend on the degree of mineral scaling in the well.
