Check with your local pool store or service
company to see if they offer
fi
lter grid de-scaling

mineral deposit buildup. It is usually due to
deposits of either magnesium, calcium, alkalines
or carbonates. Removal of these deposits may
be accomplished by soaking the
fi
lter grids in a
plastic tub or pail with six (6) parts water to one
(1) part hydrochloric acid (muriatic acid).
