And what Pete said.. lol It's nice talking in this forum sometimes.. and I 100% agree.. if your dripping 10% a day.. if by some reason your water goes, or you have to shut it off ect you'de be good, might hit a mini cycle.. but you never "really" know how a system will react until you put it to teh test in these instances. BUt I'de be wayyy more comfortable w/ the 10% drip vs if you where doing 50% and something happened to your water source ect.
And I am one of those crazy people who keep their rays in 8.2PH KH and GH are both off the charts ( wasn't our house so couldn't hook up an RO system ect).. and I do water changes in response to my TDS not nitrates. My TDS rises faster then my nitrates do. My retics are thriving in it. I will be moving them hopefully by the end of the month into better perameters... but they've been fine for the past 2yrs in the 8's
