Q;
How is UNRUST Stain Preventer different than the other liquid products on the market?
A;
UNRUST Stain Preventer is 100% chemical concentrate in the dry crystal form. You mix it with water to activate it. This gives you fresh chemical and saves you money by not having to pay for a watered down product.
Q;
How much iron will UNRUST Stain Preventer work on?
A;
We have one well where the iron content is 30 ppm. It does take a lot of UNRUST Stain Preventer, but no iron stains.
Q;
How do I know, how much of UNRUST Stain Preventer to use?
A;
You can get your water tested for Iron content and Hardness level by either finding someone in your area to test for you or you can send us a sample and we will test your water free of charge and let you know how much to use.
Once you know your water test results the rule is to add one scoop of UNRUST Stain Preventer for ever ppm (parts per millon) of Iron that you have and 1 scoop for every 5 grains of hardness to 30 gallons of water.
I.E.
If you have 3 ppm of iron and 20 ppm of hardness you would add 7 scoops to 30 gallons of water.
Or if you don't want to get your water tested and you already use a liquid form of Rust Preventer mix 8 oz. of UNRUST Stain Preventer in 1 gallon to get the same as 1 gallon of the "Other Brands" liquid chemical. Then add it to your chemical injection tank, as you normally do.
I.E.
If you use 4 gallons of liquid chemical in chemical tank use 4 cups of UNRUST Stain Preventer.
Tip;
You can just add dry UNRUST Stain Preventer to your chemical tank and add the water, to the tank, to mix.
Q;
Does the hardness of the water have anything to do with the removal of the iron?
A;
No, hardness is not a problem for UNRUST STain Preventer, however when there is a lot of hardness and iron, it may be necessary to up the chemical dosage to get to the iron. The reason for this is the hardness competes for the UNRUST Stain Preventer chemical and you need to add enough to treat all of the hardness and then the iron.
Q;
How is a good way to get the correct amount of UNRUST Stain Preventer in my water to prevent staining?
A;
Here is how to get the proper dosage of UNRUST Irrigation Rust Stain Prevention in your chemical tank.
Tip; Simply place a white piece of PVC pipe with one part of it masked off with tape, 
in the area that has the worse staining problem. After that zone runs and the white PVC pipe drys, pull back the tape, if you see the starting of a stain. Add 8 more ounces of UNRUST Irrigation Rust Stain Prevention to your chemical tank. Do this until you get the proper mixture.
Q;
Does UNRUST Stain Preventer go bad, if it is stored over the winter? I had some get hard because I did not seal the lid properly.

Q;
Can I add UNRUST Stain Preventer to my chemical tank, if it has some remaining liquid chemical in it?
