Taiyo Pluss Discovery CO2 Bubble Counter, 3 Inches, Metal, Planted Aquarium (Pack of 1)(Color May Vary)(Weather Resistant)

Just as it is for us, the right balance of carbon dioxide in their saltwater and freshwater environments is vital for the wellbeing of marine life. Too much or too little spells trouble for your fishy friends and the results of which definitely show up rather quickly. And that is why a good bubble counter is an essential tool for any responsible aquarium owner looking to make their home set up complete. The ideal CO2 concentration in the water tank depends on several factors like water flow, planting, surface ratio, pH level, and carbonate hardness (KH). However, a rule of thumb is 10 bubbles per minute per 100 liter aquarium water. Supplemented with robust material instead of the traditional breakable glass, you can expect this bubble counter not to break on you as quickly and easily. Also comes with a built-in check valve that fits any standard needle valve beautifully. A needle valve that is attached to the regulator can be used to fine-tune the amount of bubbles (a.k.a. CO2 levels) until you are happy.
