Hello,

I use Ben's kit to test for everything but I go to the pool store to test for Total Dissolved Solids. I use HTH Shock n Swim periodically to keep Calcium level around 230. I use regular 6% chlorine bleach for daily chlorination.

Pool Size: 25000
Type: White Plaster
Pool Temp: 63 degrees


Using the PS233 the numbers are:

FC: 5.0
CC: 0
TC:5.0
CYA: 65
TA: 120
CAL: 230


OK, here' s the question. Pool store tells me the TDS is 2100 and that I should consider draining and refilling. Is that necessary? What is an acceptable level of TDS?

Thanks
Dianne
