Clscea Aquarium Auto Top Off System Water Filler Compensator Blue

The media could not be loaded.  Muy buena alternativa para un acuario nano aquí los calores dónde hasta 32° y se evapora vastante agua así me es de mucha ayuda para suministrar el líquido a la pecera de forma semi automatica

I really like this little product. You need to use a bottle that fits the threads tightly, not a regular water bottle or anything like that. If it doesn’t fit correctly it will empty the whole bottle at once. I spent about ten minutes playing with it in the kitchen sink to get the water to stop at the level I wanted. Another trick is to cut the tubes at an extreme angle to slow the flow so it can stop at the desired level. Once set up it’s great! I will be ordering another for my other aquarium.

Just a simple device that save me from getting a electric auto top off. Works on my Fluval 13.5. for about 4 days without the cover and over 10 days with cover. I use a 1 L bottle with this cap. You will need to be careful of cutting the tubes initially as that decided on the water level you like the tank or chamber you like to be at.

It's not pretty looking at an inverted bottle on an aquarium but in my case it's not the asthetic but the function at low cost. I use this on a quarantine tank for coral, it works at keeping parameters stable flawlessly.

The media could not be loaded.  Easy to install. The short tube control water highest level and the long tube is water inlet. I found a better one install to the corner to save space but this is good enough.
