I figured too, if something went wrong and it dumps the whole thing, it's only a gallon so it won't overflow or mess with salinity too bad. A learner volume.Good set up. I have one with a 20g aquarium as a reservoir for the big tank and a 5g HD bucket on the office tank. Don't waste money on a fancy container.
And it definitely messed something up last night. So the jar is half empty. So it only pumped in a half gallon. BUT. it's several inches over the top of the sensor. WHY? What did I do wrong?
