Vendeur: amy4342 (873) 98.7%, Lieu où se trouve: Maesteg, The Vale of Glamorgan, Lieu de livraison: GB et de nombreux autres pays, Numéro de l'objet: 201732122140 You are bidding on a genuine Cal Aqua inline co2 diffuser to fit 16/22 tubing. I've used it for years and found it to give excellent diffusion but I've now given up the planted side of the hobby. I've cleaned it as well as I can without a brush, but I'm sure a cotton bud or something similar will get the rest of the algae. There is also some algae on the disc, but nothing a good soak shouldn't sort out. There are no chips or cracks in the diffuser. Please feel free to email with any questions. Happy bidding!
