AQUA-CLEAR® MGA dry blend of granular acid and additives are used in the removal of iron, manganese and carbonate scale. It retains strength longer than most liquid acids, which increases its cleaning capability.
The previous concentration of AQUA-CLEAR MGA acid is recommended for a complete reconditioning of an existing well.
Calculation for volume in well:
Gallons per foot = (diameter, inches)2 x 0.042
Liter per meter = (diameter, millimeters)2 x 0.0008
Displace solution into the well screen and formation, then surge, swab, agitate or jet well through screen and gravel pack for 20-30 minutes.
Allow to stand in well for up to two hours and then repeat activity approximately every two hours for a period of 24 hours.
Pump well to waste until well water pH is within 0.5 of original well pH.
Note: Wastewater can be neutralized by adding soda ash or lime
Chlorinate well and reconnect to the water distribution system.
Caution: Never mix chlorine and AQUA-CLEAR MGA acid in well
If necessary, AQUA-CLEAR MGA acid may be poured directly into well as per treatment table, but results will not be as good as if applied in a dissolved form via a tremie pipe. The undissolved form will require more mechanical agitation.
Occasionally for heavily encrusted wells, it is desirable to brush or scrape the casing and screen, then pump or airlift the debris to waste prior to treating with acid.
The following charts recommend a concentration of AQUA-CLEAR MGA acid that is suitable for a typical maintenance treatment of an existing well.

The concentrations of AQUA-CLEAR MGA acid shown in the previous tables do not take into account the 100% excess volume required to compensate for the water present in the formation interface and gravel pack. The previous tables only account for the product concentration required for the volume of water occupying a 10 foot or 10 meter section of a given size of the screen.
For other diameters:
AQUA-CLEAR MGA acid is safe to handle when in dry form, but when mixed with water it should be handled in accordance with recognized standard practices for handling corrosive and acidic materials (refer to Material Safety Data Sheet).
AQUA-CLEAR MGA acid is packaged in 5-gal (19-liter) full opening pails with a snap on lid, containing 50-lb (22.7-kg).
AQUA-CLEAR MGA acid can be purchased through any QUIK-GEL® viscosifier distributor, or by contacting the Customer Service Department in Houston.
