Let's here it for experience!

That's the great thing about this site - there is always someone who knows.
We have lots of bacteria - and would gladly share with anyone in our fair city should they need it. Sounds disgusting - sharing bacteria -but if you told me last year that I would be siphoning fish water and putting my fingers on dried fish and wet mosquito larvae without a care,I'd have thought that was disgusting (and probably thought you'd lost your mind too)

It is amazing what a few months , a couple hundred gallons of water, and thousands (or millions) of bacteria can do to a person.
Sorry for the semi-hijack! Back to the busniess at hand. Filters and how to manage the canister and HOB maintenance.
