I have a 90Ltr aqua one and it has the usual problem of the powerhead sounding like a jackhammer, so I was gonna buy an All Pond Solutions external cansister but I dont know which one. They do a 1000Ltr/h, a 1400Ltr/h with 9w UV lamp or a 2000Ltr/h with 9w UV lamp. I was thinking of the 1400Ltr/h because I thought the 2000Ltr/h would be far too much turnover. So my question is which one?
