Instructions:

1, Fill the main body 3/4 full of water (regular tap water is fine). 2, Determine the position of the foam counter and cut the CO2 tube to the length you want. (Make sure it is placed vertically) 3, Then connect the check valve with the CO2 tubing (pay attention to the air inlet and outlet direction); 4, Connect the CO2 Diffuser and CO2 system (CO2 generator or cylinder); 5,Use the stopwatch function of your mobile phone to count the number of bubbles in the bubble counter (For example, 31 bubbles in 30 seconds are about 1 bubble in 1 second.)

★ Helps to count the amount of Co2 injected:

The bubble counter is indispensable with any CO2 setup system because it helps to count the amount of Co2 injected. Excess Co2 levels will lead to a sudden drop in pH level & cause severe stress to your fish. On the other hand, the underdose of Co2 will affect the growth of your plants. When the counter is set up, you can count the number of bubbles per second to estimate on the Co2 injection rate.

★ Easy to Use:

The bubble counter has a larger space, which can put more water, and it is convenient to use it without frequently adding water to the bubble counter.

★ Transparent Material:

Glass material, smooth lines, transparent and beautiful. Clear and precise bubble formation allows you to count bubbles with ease.
