Would not clean any other filter material under tapwater however.
1/2 cup to one cup per 10 or 20 gallons gallons might be place to start.(depending on current hardness or lack thereof)
Could place this amount in 5 gal bucket or 20 gal tote,tub, and see what it does to hardness over a period of a week and adjust amount if needed.
Above is wrong!!
I should have noted 1/4 to 1/2 cup per 20 gal and after going back through this thread and parameter's posted,,Byron is prolly right, in pointing out that it may take much less than the afore mentioned amount's.
Amount I mentioned would be for those who have soft water, as opposed to moderately hard water that OP has posted according to strips.
Do test the water in tub or bucket before using in aquariums holding fish, lest sudden change in chemistry bring more problems than help.
