easy to set up, little maintance, works great. i love it. only thing is finding out how much effulent to drip so that it keeps your
alk and calc levels where you want it. i got mines set up and its keepin my levels pretty stable. i only test once a month for
alk and calc now and the test stay pretty constant. i rarely add calc and
alk now. ohh 1 thing, get the
ph controller. its hard as heck to keep levels constant if you dont have a
ph controller.
