Hi - I have 6 largish GF in 60 gallon tank, no gravel, Aquaclear 300
and Eheim wet and dry.

I change 30% water using siphon about every 5-6 days and clean out
Aquaclear 300 filter every time with water change, but not the Eheim
wet and dry. I usually clean Eheim wet and dry about once a month or
perhaps a bit longer. My nitrate reading is usually between 10 and
20.
