I have had a juwel 4 plus powehead running on my 180ltr freshwater tank without the filter and it has just gone bust. I need a new powerhead very quickly as the juwel filter does not airate the water. I was looking at the seio 620 and the rena flow 2000si does ney1 have either of these and can you tell me do these airate the water well??
Any help appreciated
Thanks
