ok first of all i am completely off grid solar power only with a well my problem is for my 120g reef, i already have RODI system here but even with RO my ph is 4.5 its totally terrible and at the well comes out blood red but goes through many filters even when you fill up the bath tub you cant see the bottom its murky on my 30g reef i did a mix of ro water from the store and neighbors tap water no problems at all algae wise but what i was asking is if i use our ro water could i just use a buffer to get the ph up and be safe or what should i do ....... btw our water has lots of iron in it i will do some more testing tho on the ro water
