I am considering replacing half the bio filtration in eheim filter(substrat Pro) with more of the blue mechanical pads for same, and then after a couple weeks ,,,replace the remaiming half with same.
Am hoping to get a little more flow from the 2217 model which is a bit small for 75 gal (actually 80 gal but subtracting for substrate depth).Can't afford another filter right now.
Would this help get more flow, or would fewer pads than four be needed? I believe not much biological filtration will be lost considering bacteria over time,, will colonize on anything placed in the path of water but would welcome thought's /comment's from those who have or are doing same, or similar.
Seem to remember Ceg suggesting more flow is capable with this approach.
I have fairly large fish load in non CO2 ,low tech tank and will forego this if it will cause more problems but thinking maybe plant's could also benefit from less competition for NH4, NO3 but I am not expierienced enough to know .
Would do this slowly considering the fishes, but would not consider it if no gains can be made.
Many thanks in advance.
