I have been using fluval for years. I got so attached to it that I would only use fluval. I have a fluval FX4 running and I have had it for 6 months and it’s honestly been one of the best filters I have ever used... until tonight. I did my usuall filter clean and did the same steps and same procedure I always do and when I plugged it back in, water went EVERYWHERE. I have carpeted floors and they were soaked. I used every towel I owned to clean it up and have 3 fans running. Then I read the instructions and everything I did was right and tried it again and it leaked worse this time. I have been so attached to fluval and now it may be my least favorite brand ( or I’m just pissed my floor is soaked). Just wanted to share and also let out my anger lol. Times like these make me want to stop keeping fish.
