Ok guys, this seems to be an issue with me, I just upgraded my tank to 55g fowlr few inverts. the circulation in the tank is ok I think, but i still added a wavemaker and have been watching my anemones dance around quite a bit more than in my 29g without a wavemaker. fish dont seem to mind, question is, is it necessary to have all the water movement in a fowlr? what is the main advantages to all the water movement. never worried about this before. thanks for any imput.
