This probably is the stupidest question on here for a long time but here goes.....
I have a Fluval 306 filter been up and running for a few months now, flow still as good as first day but thought on my next weekly clean I should at least examine the filter sponges.
Now here is the stupid question!
Do I empty the water that is in the cannister out or do I leave it in ?
I am just not sure if this will contain beneficial bacteria and will do harm if I pour it away
As i say almost too embarassed to ask!
