Make sure you are using RO water and keeping nitrates and phosphates in check.
I been using TAP WATER all along. I know now that I need to have RO water, but can't seem to find any at all. I went to Wal-mart to get some but did not see a schedule showing the last filter chance. I guess RO water with old filter is still better than TAP right? Trying to safe up now to buy a good RO/DI unit.
Thanks for all of you for your input.
