New PS234 ALK results don't match old PS233

[tmredding]

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
