Review: CO2 hose is superior to others I’ve used! - When using CO2 in your aquarium, it’s important that you use a line/hose that will withstand a little pressure. CO2 line/hose is more rigid; less likely to kink. After researching the product from different sellers, I settled on this product offered by this seller. The hose is good quality and the hose suction cups hold the hose securely. You also receive two anti-back flow valves that keep water from flowing into the CO2 unit. Time will tell how this product holds up. I believe it’s the best quality I could find at a very good price. Suction cups seem to be better quality than once I have purchased in the past. But, suction cups can be replaced at a cheap cost. The most important is the hose and I believe it to be off excellent quality! I give this seller 5+ stars!
