New PS234 ALK results don't match old PS233

Hi, love the new kit but concerned about difference in ALK reading.

PS233 FC 3 CC .5 PH 7.4 ALK 130 CAL 270 CYA 75 Temp 84

PS234 FC 3 CC .5 PH 7.4 ALK 200 CAL 270 CYA 75 Temp 84

Inground 18 x 20, vinyl, sand and triclor pucks. I have done the ALK test numerous times with same results, dip sticks lean more towards lower reading
but only go to 180. Has anyone else seen this problem?

Thanks, Terry

I've asked Ben to take a look at this post for you.
