No worries. If it is the same issue then it would be interesting to see if there our systems have something in common that could be causing it. You said your system is two months old? Are you 100% dry rock right now? Also let me know if the UV works for you...

What else could it be?

I did come across a random reference on RC about a guy having cloudy water that only went away when he changed his RO membrane... he didn't go into any detail though. Mine is four years old, but I had it in storage for two of those years (it didn't dry out). It is still reading 0 TDS though so it should still be good...? Now that I think about it, it does spike to 40ppm for the first 30 seconds or so before falling to 0. Would that be an issue?
