Hello.
I have a 65 gallon tank With an undergravel filter, and an internal filter that does 350 gallons/hr. i am going to get another in internal filter that also does 350 gallon/hr. when i do this do you think i should get rid of the undergravel filter or leave it in there.
Thank you for the help

Good morning Zach. Personally I would remove the under gravel filter. I feel like they are waste traps and that's about it

I agree with aquarist..especially with the big waste producers you have in your tank...be prepared, theres going to be a TON of waste that comes out from under that UGF when you remove it...do you have an issue with nitrates by any chance?
