Review on 🧽 Hagen Fluval Edge Foam Pad and BioMax Renewal Kit, Pack of 3 by Todd Saunders

Although I'm fed up with the maintenance for my aquarium (I have 2 tetras but have gotten a lot more in recent years) , I'm leaving I still rely on Hagen medium to protect the aquarium from chemical stress and bacteria. The pump on my 12 gallon Fluval tank has been running flawlessly for almost 7 years - it's amazing. I clean it along with the impeller and use the Fluval environment. I usually change my medium every 3-5 months.
