How about a bombing of photos of what my osmolator nano did recently to my living room? Supposed to shut off after 1 minute of continuous filling….didn’t happen and drained a freshly filled 5 gallon ato into a fluval evo 13.5. Dropped salinity from 1.026 to 1.018. This is my second tunze nano to fail, first one just quit working no matter what I did, think it’s a controller issue and not a pump issue. Needless to say switching to reef breeders now!
