My first marine reef tank was a Rekord 110 but now I use it as my quarantine tank. It was too small and gets too hot. I have upgraded to a Juwel vision 450. They guy that imports them into NZ is in Chch and he set mine up with a sump but the overflow box is too small, I have put a durso standpipe in it to cut down the noise which is working well and I have the sump in one of the cupboards but it is a bit small, but I do love the Juwel tanks.
