I have two Gyers 150 almost a year old. They have been cleaned every two months, since I bought them. I run both of them at 60%, and that was more than enough water movement. Last couple of weeks, I noticed both became weaker. I thought they need to be cleaned. I cleaned both of them with water and vinegar, and they still weak. I am running them now at 90% to get the same water movement that I used to get at 60%
Anyone else noticed anything similar?
