New Filter Considerations. Help needed!

[mpmistr]

I run an Eheim Classic 2217 on a 40 gallon breeder that houses three large ACF. I do not throw away the media, just rinse and reuse, using old tank water. My tank has a lot of fast growing plants like water sprite, duckweed and vals. My nitrates do not go over 10ppm and I test my tank before I do my weekly partial water changes of about 30%.

Do answer your question, Eheim 2217 works great on a 40B, some may say its overkill but I prefer to not have to worry about filtration. The current it creates is nominal, but you do want some current otherwise you get bad things like cyanobacteria and dead pockets.
