I recently got an Apex controller with couple of probs. But my tank is not ready. ( I got the controller because the price on that one was good and I couldn't skip ). Any suggestions how to keep the prob wet till I set my tank ?
If they went dry the consensus is they are usually shot. If you calibrate the ph and it holds then it should be ok. I know when my unit shipped the ph probe came with the tip inside a small container of calibration fluid. The container was about the size of a salifert powder reagent bottle. There was a hole drilled in the lid and if I remember right an o ring. If you got a good deal I wouldn't worry too much you can always get a new probe and it won't break the bank. Best of luck.
