just looking around for a drop checker for my tropica aquacube as ill be injecting co2 and ive realised the ones ive got look HUGE in the tank. Havent had a proper trawl of all the sites yet as im in work but does such a thing as a Nano size drop checker exist or has anyone put any other solutions into their small tanks??
