ive never heard of negtives of using 0 TDS water.
Thats great, but I listed it for you. Its called soft water. Water that is mineral defficient and and has a very low pH.
nor people who mix rodi with tap......why pay $300+ for a rodi system if your going to mix tap water in to the product water? mise well just take the waste water from the rodi and put it into your tank
See above statement for why you would use a 50/50 mix.
city not that bad? did you ever send it out to get it tested? may look clear........but its dirty. city water is the worst. unless by city water you ment well water?
Maybe your city water is the worst, I dunno? Like I said, it varies from each municipality. No, I didnt test it. No, I am not going to. I used it, and had coral growth and nothing awful as far as algae grows.
.........any massive problems?. i dont want any problems, massive or not
What will a refugium absorb? Chloramine NO
Never said it would. All i said is that they will absorb undesirables from the tap. They sell tap water conditioner, and it nuetralize Chloramine...
most convient. and im not aweare of any other ways.....
I listed them in the last post, and your not open to them.
