Hello all getting ready to leave on 1 week vacation. Numbers this morning FC 7.5, TC 7.5, CA 350, Alk 60, CYA 40 PH 8
I plan to put 1-2 Trichlor pucks in a dispenser while we are away. My understanding is that the pucks lower your Alk levels and PH. So should I add some baking soda to increase alk before I leave and put pucks in dispenser?
I will only be gone for 6 days. Do I need to worry about PH getting too low??

Do you plan on lowering the pH with muriatic acid now? 8.0 is a bit high (scale). You might lower the pH into the 7s now, then test the pH and TA again just before leaving. If the TA is 60 or above you should be fine. If the TA hits 50 or lower I would increase it back to the 60-70 range. With a CYA of 40, you can also increase the FC up to the SLAM level of 16 which will give you 2-3 days of good FC as well.
