Review on Fluval A20021 X06 Primer Assembly: Efficient and Reliable Solution for Optimal Aquarium Filtration by Melissa Shoulders

If you have a Fluval filter that won't refill, don't buy a new one! Fluval canister filters are great: efficient, quiet, efficient, well designed. Unfortunately, these little primers are pretty easy to break. Good luck trying to get the filter to work without a primer. Luckily, this little kit makes it easy to fix. Instead of spending tons of money on a new filter, just get it fixed! FYI: There are many videos on YouTube showing how to change the primer. This is a very simple operation. Much luck!
