Unhappy Gray Water Monitor

We're on a month long vacation trip that started in Collierville, TN going west to Utah on I-70 and returning on I-40 and we are in Flagstaff, AZ today. The last two stops, Provo, UT and Mesquite, NV we drained and flushed both the Gray and Black tanks at least three times, put in the mixture of Calgon and powder and let those stay in the tanks while traveling. We've even tried the Ice plan with no results.
My problem is the gray tank monitor reading still reads 2/3rds full even after flushing and draining. I use a Hydroflush for the process.

Any suggestions as to what else I need to do to solve the problem.

I wouldn't worry myself about it. There are any number of threads on this problem, mostly with the black water monitors, but grey also. My grey monitor recently began to show a quarter to half full after emptying. The black monitor has been stuck on full since shortly after purchasing the trailer. Same thing with our previous trailer. The important thing is to continue to maintain your tanks to avoid odor problems. You can try any number of remedies on the monitor problem, but what's the saying, grant me the serenity to accept the things I cannot change?

Agree. Unless you want to replace the sensors with something that will not give false readings, just don't be consumed with it. Most campers, know from experience how many days they can go between dumping tanks.

Just keep some liquid in the tanks to prevent any solids drying out between dumping and life will be much simpler.

Thanks a bunch, I agree. I will always just keep caring for both tanks.

Actually I have some snake...err special mix that I would be more than happy to part with for a small fee...:hihi: The only time that my sensors worked properly other than the fresh water was the day I brought it home and they were empty. As others have said forgetaboutit...when the terloit gurgles time to dump the black tank; when the water stops draining into the grey tanks...time to dump them. If the fresh water sensor ever dies I will know when the pump doesn't push any water I will know it is time to refill the fresh water tank.

Dump a bag of ice into your black tank the next time you tow the trailer. The ice will help knock "crud" off of the sides of the tank and the sensors.

No I am NOT retired. I work full time.:D
