I have a 55gallon with 24 mbuna I purchased about 3 months ago and I'm looking to change my filtration as I expected I would need to upgrade. right now I have a topfin silent stream 75 and two 4.5 in sponge filters but I'm not entirely happy with the job they are doing mechanically. so the question is do I add AC 70, AC 110 or sunsun canister. and if sun sun which one. love the the canister for media but hate it for setup with tubes ect. i like the aquaclear for ease of setup and maintenance but hate to see it and hear the water flow. thank u in advance
