Do I need a wavemaker?

[DebraLV]

A power head you can manipulate. It doesn't need to be a wave maker. However, there are cheap jabaeo wave makers. They are bulky and ugly. Unless they changed something.

Oh, ok, thanks. I don't have a powerhead filter, just a plain, ordinary, cartridge pump for a 10 gallon.

if the op just wants to use job filter, by all means its absolutely fine fowlr. Even for soft coral.
