Fluval FX4 Stopped Working

  • We are currently upgrading MFK. thanks! -neo
Also instead of using the ammonia and charcoal bags I just stuffed more bio-rings in instead.
 
One last tip. When I bought more bio-rings I got the ones for the AC50. They are much smaller and can cram a lot more in than the normal AC110'S bio-rings
 
Great tips - thank you! I purchased one last night, need to grab a second when they are back in stock.
