I just had a thought Jason. I do have a skimmer which is still running itself in. There are a few (not loads) but a few micro bubbles around.
Could this be causing a problem with the meters ability to measure the resistance, or whatever it does?
thanks for your help, im getting so panicky now with the Tubastrea in there.
