I need a new pressure tank. I think I have a 42 gal tank. I am wondering if a bigger tank will be more beneficial with 2 grown ups and 3 kids? Also I have a really old Rain Soft water softener system. It works but I am getting a funny black slime out of the discharge pipe which has water coming out of it all the time. A small steady slow stream. Any suggestions? I hear they have filters in this type of system? its a 2 tank system. Thanks for any suggestions.
