    I have a TDI reading of 36ppm out of my hose. Can I use this for water changes? I have an RO/DI but it takes a day and a half to fill 30 gallons. I have a 125 FOWLR with live rock. I wanted to see if this was acceptable as I will likely do more water changes. Thanks!

    Better to use the RODI water. Do you have a catchment container to store the processed water. I set up a tall kitchen garbage can with a small powerhead for circulation. Also, if you do a gallon a day water change, you can avoid needed to do large water changes.
