I have two canister filters running in my tank, I've never cleaned the hoses (flexible pipes) that connect the canister to the outlet and inlets.
I clean the baskets and filters like every other week, with tank water, to remove the gunky stuff.
But I have seen that in the flexible pipes have been growing crusty stuff, like gunk, like algae!
My questions are :
Is this kind of build up normal? Are these the good bacterias? Do I need to clean these pipes?
Once in a while when I turned on the filters after a PWC
, they expel a lot of this crust through the outlet, making the tank dirty! I hate this.
Thanks for your replys!
