    either your heater is currently running at full tilt or your thermometer needs re checking as i would have thought 22.4 degrees is very unlikely

    I really thought this myself, find it very hard to believe a pond could be this temp outside unheated. Or maybe we have all missed some thing that stu has done lol

    If there's any interest I could set up a Google Drive (used to be called Google Documents) spreadsheet where we could all record our readings?

    https://docs.google.com/spreadsheet/...EdWWmRreklHdXc

    Anyone should be able to view it, if you want to edit it to add your own results pm me your email address and I'll add you.

    If anyone doesn't want their data shown pm me and I'll remove you (and accept my apologies!)

    Sorry I should have explained. I bought a new thermometer yesterday as you guys were getting me worried.

    The heater was reading 22.2 this morning. So I took the temp from the actual pond and thee temp was 19.8. I then took the temp from the nexus pump chamber and the temp was 22.0. So it looks to me that the medo pumping hot air into the nexus is acting like a heating device. The tubing that runs from the medo 120ltr to the nexus is always very hot indeed. So based in this I will need to assume that the pond water is always 3 degrees colder than the heater reading. This is the reason that my temps seemed excessive at first. So to heat at 16 degrees I will need to set the heater to 19. Anyone else have this kind if change between filter and pond?

    Thanks Miles.

    I've put yours and Mark's readings in.

    I was only thinking of one reading per day to make it easier to read, do you think that's OK?
