Refill Fix is a new low tech device from Aqua Medic that is ‘designed’ to provide a small amount of make up water lost due to evaporation. We would only loosely describe the Aqua Medic Refill Fix as being designed since it’s not much more than an adaptation of per watering bowls, devices, and even feeders.
The way that the Refill Fix works is by simply attaching a water bottle to the female threaded receptacle and inverting it, the base attaches to the side of the aquarium walls with small hoses to allow air to trickle in, and water to trickle out. There are adapters to accomodate a few different tank side wall thicknesses from 3 to 10 millimeters, and the size of your reservoir ultimately depends on the size of the bottle you select for this purpose.
We can imagine some scenarios where the Aqua Medic Refill Fix is a very clutch form of auto top off for the tiniest of tanks, or for small aquaculture applications like auto feeding of phytoplankton to copepod cultures. This gravity fed style of ATO is among one of the oldest -originally called a ‘Glug Jug’ = but we do have some reservations about placing that much weight on the edges of a rimless tank.
One little bump of the tall water bottle could act like a lever and easily snap the thin walled glass, not to mention the stress of having that kind of pressure resting on the side walls of nano aquariums. Depending on the price, we might pick up one of these nano glug jug adapters for use in hyper specific applications but don’t expect us to pay anything more than ten bucks for the convenience of what used to be a simple DIY project.
