How much water does your tank evaporate each week and how large is your tank? Do you take any precautionary measures to limit the evaporation amount?
I go through about 30 gallons a week on a 240 gallon tank. Feel like that is a lot, but in my past set up, I didn’t monitor it as closely as I do now. My Rodi used to run to my ato non stop refilling it. After I moved, I had space for a small fish room so I switched from a 5 gallon bucket to to 32 gallon brute can. I let it run out before I refill. Which is also WAY better for your RoDi cartridges!
