Great review! It looks like a pretty cool device but seems like the maintenance might be a bit much but maybe the tradeoff is that you can measure so many tank parameters. With traveling so much how do you keep up with maintenance?
I never thought that graduated cylinders could be significantly inaccurate. Will have to keep that in mind.
Thanks for doing a long term review! I always feel these are often missing because people like to be the first one to review a product... but when it comes to a hobby where patience is essential, having a long term review rather than unboxing and hearing nothing after that is quire refreshing!
