Question for the senior aquarists around here,

I recently started a 20g long, moved an Aquaclear 20 filter from my old established tank and added a smaller internal filter acting as powerhead and diffuser.

Params are great since the get go (ammonia 0, nitrites 0, nitrates 10ppm) due to the established filter and heavy planting.

Got the itch today to look at canister filters and found an EHEIM Ecco I really liked.

Now the question is, is a canister worth it? Seems like my current filtration setup is doing the trick so don't see a need to upgrade.

On the other hand for aesthetics I wanted to remove all the filters from the side of the tank.

Thoughts?

You've done a pretty good job of asking the important questions. It's all working pretty well, so why change? As you've noted, canisters are easier to hide so they look better. But there are some other things we might mention. I find canisters will do quite a good job without cleaning them nearly as frequently as HOB. AC20's are good filters but they have reasonably small surface area where the water flows through compared to many canisters. That leaves that smaller area to get covered/filled with debris much sooner than a canister but the bigger downfall is what happens when it does stop up. The water keeps flowing but it is bypassing the filter and going through the overflow on each side. Looks like you are filtering when you are not. On a well designed canister, all water has to find it's way through the media or not at all. You can let a canister go and you can gradually see the flow reduce, letting you see how far behind you might be.
I also found I had to replace impellers and shaft way too often as the HOB water goes by them before the media rather than the filtered water after the media. A single bit or two of sand can cost a new shaft or impeller.
So is it worth it? Depends on personal outlook but I hope I've given you some ideas.

Thanks PlantedRich!

This AC20 is only a few months old so still no issues with impellers or anything, but from what I read it will be a future issue. Also, the AC requires cleaning every two weeks as it does get very filthy.

Great job on getting the ecco - I love the one I got for my office 10 gallon, no problems at all.

Can't wait till it gets here! Already moved stuff around to make space for it.

How do you recommend transitioning from the current hob? Just moving media to the canister and let it run?

I would run both. I like having an HOB and Canister on each of my tanks. Thats just me though.

If I was going to transfer media, I would just transfer the bio to the canister and cut up the sponge filter and also add it to the canister. Only if you aren't using the HOB anymore.

Thanks for the suggestions, I think I'll go with moving the media and cutting up the sponge, as the HOB is going to another tank, plus it doesn't allow for the light fixture to be placed properly.
