yes but less likely, does he dose from buckets? check to see if the dosing pumps are running( the bar in the middle turning) or pull the tubing out of the sump and see if anything is coming out of them.
add the white vinegar to a high flow area of the sump, add it a tsp at a time, wait a few minutes and check the reading, it will probably take about 10 tsp before you see a sgnificant change.
check the dosing pumps or remove the tubes from the tank( they could be siphoning), it would be safer not dosing than dosing too much.
