Yup that's kind of why I went with the 100GPD for the long run but I still bought OEM filters being it is only about every 6-12 months when I change... I do plan ahead I have a trash can with a
float valve for my RO then treat with what i want depending the plant... yes I will even be phing my RO water when i feed it even though it becomes difficult unless using a large amount.. The last time I ph RO water I had to use ph down still and had to dilute one drop of ph down in one gallon then use that to ph the bucket of water I was testing.. I hear what your saying but anytime I check my RO water it is around ph 7 or higher still
