Hi I have the Osmolator nano but am thinking of the regular osmolator full size unit, I had one before it had a 10 second prime start up and a 10 second minimum top off time is there any way you could shut off those features and make it work exactly like the nano float valve except with the optical eye? It is for a 24 gallon nano cube, just wondering because I like the optical eye better I think it's is more reliable.
