I'm confused about powerheads

[Mark Janssen]

i had de koralia (a 4cm modesta wil swim right up to it and i got i out fast after seeing it) but returned it. they have a very wide flow so a 3000liter per hour flow is a little current compared to a 2000l per hour conventionel powerhead.

at the moment i have one eheim compact + 3000 and i want to add another one in the future (already got the pipes ready for it)

Or i wait till i get a new thank with a internal filter (made as a seperate compartment in the tank) and put a 10.000l/h pondfilter in it. pondfilters use less watts but make a little more noise.
