So I have the redsea 425g2.. I am currently away and my redsea app notifies me that my skimmer cup is full. I connect to my sump cam and see the reefmat bubbling.. This indicates that there is no water in the return pipes from the display area.. This happened already another time without me turning the valve.. does this indicate that I need to somehow clean the internal piping? Or service the valve? Or maybe change it to a gate valve? Have you experienced any of this?
