Am I going to go through a cycle if I change from hob to canister?

    I was thinking of changing from a hob bio wheel to a canister filter. I was planning on running both at the same time till the bacteria grabs hold in the canister media? Will I see a cycle ?

    Can you not just transfer the media over to the new filter, even if it mean cutting it to fit?
    The trouble with running the new & old side by side is when you do remove one you could be removing 50% of your good bacteria possibly resulting in an ammonia &/or nitrite spike

    Possibly, but more likely to see just a mini cycle. Can you just run both on a permanent basis?

    I can. I didn't know if it would be beneficial to run both

    I run two canisters all the time. U can never have too much filtration. Dont see why you couldn't.

    I run both a HOB and a cannister. If you do nothing but change filters, take the good biomedia out and put into the cannister and add maybe TSS you may be good but I would run both for a while to transfer the bio to the cannister I did
