Birm® is a clear water iron removing filter media and does not remove manganese or sulfur.
Requires a gravel under bedding.
Requires dissolved oxygen in the water supply or an oxidation value introduced into the system during recycling.
pH below 7.0 may not allow a filter to be as effective as the acidity of the water will push the iron off of the media. THIS IS TRUE OF ANY WATER SOFTENER OR IRON FILTER.
