55 gallon planted tank

I have a 55 gallon planted aquarium, right now I'm running a canister and an hob and two sponge filters. Was wanting to know if it would be okay to switch to nothing but sponge filters, will that hurt the tank? Thanks

You can definitely run a 55 on just sponge filters. 
 

Considering you have several types of filters, I’d just start turning them off one-by-one until you’re down to what you want. Shut one down, and then wait a couple weeks for the bacteria to catch up on the remaining filters. Shut down the next filter, and then wait a few weeks again. Could also reduce feeding a bit when you shut down a filter just to ensure you don’t overload the system. 
 

I have (2) 55 gallon tanks, one of them being a grow out tank for fry. There’s probably 75 angelfish in there, along with Platy’s and Cory’s I’ve bred, too. Easily over 100 fish in that tank and it runs on 2 medium sized sponge filters and a small HOB with just some sponge and an intake filter sponge. 
 

My other 55 has Angelfish, Cory’s, and Cardinal Tetras. It runs on a HOB and a large sponge filter. 
 

I’m confident either of my tanks could run on the sponges alone.

Thanks for the information, I will try that.

Well, I don`t think that would hurt anything but, recently I removed a Fluval from my 20T and put in a Penn-Plax bottom filter as an experiment (You make your own filters cut to size from whatever material you want.) so far, it's working very well. (Air driven.)

Also, I use a plenum that's the big secret no one talks about. (I don`t have many plants not needed anyway and my nitrates are usually under 0.25ppm.)

Good luck.
