Hi guys,

Just a quick question regarding filter media. My external filter comes with four small baskets inside. The top most has floss in it, next has coarse sponge, then plastic bio balls, then a final layer of coarse sponge. I'm sure I read somewhere that it's best to ditch the bio balls and add Purigen in one of the baskets.

Can you guys give some advice on how best to set this up?

Thanks,
 
Purigen will make your water super clear but its not necessary.
Just run what you have and forget about it.
 
I personally like to have the two sponges at the bottom, with the coarse one first (bottom), followed by the fine one. This helps keep more of the solid matter out of your other filter media above. Well, that's the theory - but it doesn't really work in practice!
 
less media, increase flow, happy plants happy fish...
