Ok, so we scrubbed the tank yesterday and it’s looking pretty good and after using the water we had on stock, we were running our RODI
machine today and noticed that the TDS
is at 1. Is that water going to be throw away water at this point or would it still be safe to use at that low? Also, we’ve replaced the resin filter once and even after less than 100 gallons, it’s already Amber again, so in addition to changing that again, is it recommended to change the Carbon and Sediment filters as well? The RODI
is newer than the aquarium, for several months we were getting our water from our LFS
and decided to start doing it on our own, so if there’s something we need to do differently on our end, any advice would be appreciated.
