Im 95% sure this will work just want to make sure my plan is a good plan.

I have just ordered a Hydor 350 for my 55g. I am currently running a HOB Aqueon 75. I run my own filter pads in the current filter. My plan is to dedicate the first media tray to my used/seeded media, then have the other two trays for the ceramic and new sponge. This will work right? I have a sponge filter in the tank too, its not doing much but its take the edge off. So yeah? I don't really want to run both filters for a couple weeks, I don't think its necessary.

EDIT- I got the 350, not the 250.

That will work, JUST to be safe I would continue to run the sponge too, but ya pack anything you can from the HOB into the canister, for at least a month If you keep some Seachem Stability around that wouldnt hurt either. I just did this recently moving from a marineland 360 to a fluval FX4, also run a sponge in the tank, I saw zero spike.

Good luck!

Agree with @Bizarro252. The sponge filter does help seeding a new filter. Are you adding more bio media? Just run the sponge and canister for a month or two. Check parameters daily for the first week then reduce it the following weeks. If by the first month you don't see a spike then you can remove the sponge.

I plan on getting all the media from the HOB into the canister. So there should not be a spike.

I would still run the sponge just to be safe. It's totally up to you tho.
Yeah, the sponge will be run regardless, at least for a month or two. This is my first canister filter so I just wanted to make sure there wasn't anything I was missing with the transition.

Agree, why not? Sure they can be ugly, but dealing with that for a few weeks is much better than dealing with a mini cycle!

Ah good you should have no issues then, just try to keep the media as moist as you can (or just swap quickly) when moving it
