    Chlorine testing and carbon blocks

    Residual chlorine (no chloramines) in the water mains where I live in Italy is between 0,03 and 0,05 ppm. Do I need a very good 1 mcr carbon block, or can I just get a cheap 10 or 5 mcr carbon block and replace it once a year? Is it recommended to test for chlorine after the carbon blocks, or...

    Ultra Pure Water in Reef Tank

    I have access to a lot of free Ultra Pure Water (UPW) whenever I want. I mixed up 45 gallons of it into my new E-170 and it took 14 cups of salt to get to 1.021 salinaty. I think it only should have taken me 11.25 cups. My ATO reserve is full of the UPW. Is this water too clean for a reef tank?

    TDS meter

    If anyone is interested, some Pūr water filters come with tds meters! My permanent roommate brought one home for the house. When she asked what the meter was for, I was tickled pink when I realized it was included with the set. And....it works!!!

    My Rodi Water TDS

    I have A 75 gpd RODI system, the water coming out of it is a consistent 0 tds, but my tds meter says the water coming in is only 2 tds. I was wondering if the number is accurate, and if it was if I don't need to use the RODI system at all and just condition the water?
