3 in 1 CO2 Diffuser bubble counter check valve 20mm (M)- aquarium Plant tank

The media could not be loaded. Very good product.. work perfectly..Build quality - excellentBubble counter - works absolutely okayFine CO2 bubbles - excellentBut you have to wait for 1-2 days for fine bubbles of CO2. I use it with DIY CO2 Kit (vinegar & baking soda)

The diffuser works but there was a pinhole leak that i had to seal... Frustrating
