Chaing filter types - HOB to Cannister
I am changing the filter type on my 50 gallon tank from a HOB to a canister filter. I currently have two HOB’s working but they are old and noisy, etc…. Tank is 100% cycled and I not changing any other decorations or rocks.
Is it Ok to just change the filter and discontinuing the use of the others immediately? All the bacteria are in the gravel and rocks, etc… The HOB’s both have just had complete Media changes and they do not have any Bio material other than the filter pad itself….
What is the best way to do the change over?
