Source Water Issues
I pay about 4.25 per 5 gallons of RO Salt water. I was going to buy an RO unit for the house but my WELL water runs from a 5.5 - 6.0 PH. I tested the water today with 1 gallon, and used 2 tlbs of bakingsoda and it raised the PH to up around an 8. I'm worried that the buffer in my water is low, and the PH will drop rapidly after putting it in the tank. I could be wrong, I'll test the water again tomorrow and see if its holding.

BUT, is there a solution to this problem?

Seeing as it's fresh water, it's going to run at that #. If it were salt water that's another issue.

Also, you need to check your source water with a TDS meter. You do this to ensure that your have nothing in the water and that it's pure.

investing in a RO/DI unit and a bucket of salt is the way to go.

put it this way,
$4.50x11=$49.50 just to fill it, not including weekly 10% water changes, daily RO top off water and i think you get the picture.

reef salt will have buffers for alk (as well as mag and calcium) your also going to have to purchase alk,mag and calcium to dose regularly (after testing for it ofcourse)

why would i need to test my water for total dissolved solids before i filter it, or did you mean after to ensure i was getting true "RO" water.

You test before, just to see what your quality of water is before the RO then, after the RO and then after the DI. You do this to ensure the filters are working and so that it is taking out a lot of the solids before the DI. If it's high, it might be time to change a filter if it's very low, then your filter is still good. To DI membrane is very expensive so you should always watch the #s.
