Hello,Can anyone tell me what kind of test we most have done to analysis what we have in our cistern?Had 2x done,still don't know why we have blackish,dark brown sediment @ bottom when test say's mim.amout of manganese?
test =PH 7.34
=Iron <0.0100
=Hardness 192 or 12grms
=Tds 262.0000
=Total Coliform 6
=E-Coil Positive
First will have a 2nd Manganese test BUT what else can we have tested before I place a Ultraviolet Purifier in?I have a softern and will replace the bed with greensand or birm? Can this blackish sediment be a mold?Thank-you!!!!!
