Dario L. at 11.02.2016: Perfect balance between quality / price. Essential for medium/large planted aquariums. Great quality finish, easy to refill (universal external valve). I have it for two years and it is certainly the key to maintaining my high tech aquarium (240L). Very happy with it.
Hrvoje V. at 01.06.2016: Very good and high quality. Valve is great and don't buy others cheaper becouse there s a reason why is cheaper. Valve is good protected and connection on bottle is smaller and safer for bottle. It great for well planted aquarium. It's working on my 600 aquarium for about 3 months with automatic mode on-of jbl proflora m2003.
