Review on FZONE Aquarium CO2 Generator: 12V DC Solenoid with Bubble Counter & Power Adapter by Irene Bra

Excellent product, excellent seller, goods received, defective solenoid found. The seller fixed the problem immediately. Thanks again! Good quality product and easy to use. The secondary gauge doesn't work, but I don't mind since I use the bubble counter as the primary dosage measurement. I use it in a 20 gallon planted aquarium. With 20 shrimp and chicken for livestock. And valisneria + dwarf grass + scarlet temporal. 1-2 bubbles per second makes my plants pearly and the fish look great too. Long live photosynthesis :D
