mutley29 June 5, 2005 Share June 5, 2005 Hi All I'm not sure whether its early on a Sunday or just me but i don't seem to be able to find replacement probes for this Controller: Premium Aquatics The controller probe in my sump at the moment is telling me my pH is dropping to 7.6 even after calibrating , but salifert tests are telling me it's all good at 8.2 So i was wondering if the probe was on it's last legs and needed replacing Anyone know where to purchase said probes Any help appreciated Anton Link to comment Share on other sites More sharing options...

emissary June 5, 2005 Share June 5, 2005 Hmm well, another thing you could try is perhaps to soak the probe in vinegar to clear off any build up... Link to comment Share on other sites More sharing options...
