Alk keeps dropping

[ngarcia11892]

hey everyone, finally got a Neptune and trident as I travel a lot n wanted the monitering. The weird thing is my alk has been consistently dropping and I keep raising my AFR dosing on a sentia dose. PH has also been steadily raising. (I put chemi clean for cyano so I think that’s why)
Could those be related. I was testing for AFR with a Hannah and it seemed consistent but now the use seems to keep going up. Trident is 2-3 weeks old n calibrated.

Are you verifying the results with your Hanna to make sure the Trident is accurate?

Yes results are very close

tank inhabitants would help.... things consume alk obviously. Even my tank uses some alk, but not a lot, and its not heavily stocked yet.

Just throwing stuff out there. Have you verified the calibration on the doser to be sure it's adding the amount it is supposed to.
