Hi, thanks for the help. I am not getting any readings to amount to anything, but there appears to be some clearing. I am ready to go and dump about 10 gallons in, will that be okay, or too much at one time. Going by what is being said, I really need to get it up there to 15 and hold. So how much do I dump in at a time. We have been doing 4-5 gallons up until now. It is getting there, but not in a timely fashion. I can be patient, if that is the way to do it. Thanks, Kathy
