Calcite filter maintenance
I am on well water and have a 1.5 cu ft calcite filter with a backwash system that flushes every 4 days and a separate water softener system. The water is very good in this location; not very hard and not a lot of iron. There are only 2 of us in the house currently, so not a lot of water usage.
My question; I've been topping up the calcite filter each year to replace the calcite that has dissolved. Do I need to break the system down and flush it out periodically. By that I mean do I need to dump out and refill the tank with the gravel base and all new calcite or can I just keep adding calcite to it indefinetly.
Someone told me the calcite would harden over time and solidify in the tank, but I can't find any supporting material for that on the Web sites I have visited.
