I talked to neptune about the rising CA. Its a known issue for some they said. I was told they are working on a solution but still trying to isolate the cause from users that report it. Again this is for the low reagent causing rise in CA and not just regular abnormally high readings. May or may not be related.
Recommend starting a ticket with neptune as the more people that they are aware of with this type of problem, the easier it will be to find similarities of setup and then the cause/fix.
They have certain questions about placement and some other factors that could guide them to a fix.
In the meantime I bought the needle guides from
@Brasileiro561. Came in fast and hes easy to deal with. Will put those in on next reagent change.
