How to clean out external fluval?

[timsedwards]

Hi guys,
My external Fluval 304 seems to be making a non consistant injection of water back into the tank, suggesting it needs cleaning!
I just wanted to check it is fine to take all the sponges out and clean them? Any thoughts anyone?
All the best,
Tim .

I don't use sponges in mine. I run Seachem's DeNitrate and Phosgard and use it for the spray bar water circulation. Sometimes I run carbon. My LR and DSB seems to do a good job producing bacteria for the tank. Every three months I chang everything in the canister filter.

Hey there,
OK thats great thanks for the link, so cleaning it and what have you will not cause spikes or anything silly like that?
Cheers for the help,
Tim

I clean mine once a month and never had any problems. No spikes or anything like that.
