PROBLEM: Staining appears as discoloration on pool surfaces. These stains may be green, blue, purple, gray, reddish-brown or beige to brown.
SOLUTION: "Permanent" stains (ones not easily brushed off) are typically the result of some chemical imbalance or metals present in the water.
PROBLEM: Gray, green to bluish purple stains.
SOLUTION: Most likely copper, possibly iron.
PROBLEM: Reddish to yellow-brown stains.
SOLUTION: Iron is the most likely cause.
PROBLEM: Medium to dark brown stains.
SOLUTION: Uncommon, but the presence of manganese is often the cause.
PROBLEM: Beige to tan stains on plastered or marcite finishes.
SOLUTION: This is a calcium or silicate scale build-up. Although scale is white, dirt is trapped in the crystals as they form.

SOLUTION: All these conditions should be treated by your OMNI® Dealer. The sooner you react to any stain, the greater the chance it can be eliminated.
