Wat is this product?
Is your tank overgrown with filamentous or bearded algae? Or your plants lack color, seeming to fade more and more every day? Chances are you’re running low on CO2, which is one of the most important nutrients for your aquarium plants.
But how do you know exactly how much to add to prevent growth problems and algae?
Sounds difficult, yet it doesn’t have to be. This “Bulb” CO2 tester shows in a very simple way whether you have too little, too much or just enough CO2 in your aquarium.
