Aquaone Protein Skimmer G224

Hi,



I am looking for any advice or experience any one had with these skimmers? The price is very low, is this the case "you get what you pay for" or is it a skimmer worth buying?



The tank is 240 litres with a 90 litre sump

Or would i be better of going for something more expensive? maybe a second hand deltec? Again if anyone has tips or experience buying second hand, im looking for any suggestions :)



Thanks
