Or if you want to compare by flow then a Eheim 2071 is 12w and good for up to 250L at 950L/hr but yeah the 2071 is way more expensive. The 2213 is only $20 more brand new but you can pick them up on trademe for between $50-$100.
Sorry I should of been clearer. For example an Aqua one CF1000 is good for up to 200L and is 30W compared to say an Eheim 2213 which is good for up to 250L and is 8w.
Great filters. The only downside is that they are about double the wattage of an Eheim equivalent filter. If you aren't worried about that then get one.
Has anyone got any balansae Available? wouldn't mind some other types of Crypts as well. Would prefer in Auckland area but would pay for shipping from outside.
If you are looking for ideas here is my sump. I have the inlet fed into the bio balls chamber then from there 10ppi, 20ppi, 30ppi and synfil poret foam then goes to the pump:
