How does water temperature factor in to water testing? It isnt mentioned in my DPD test instructions, didnt catch the guy at Leslies checking the temp when they did a test for me.

The water temp changes the CSI (calcite saturation index), which shows the likelihood for corrosion or scaling of the pool surfaces and equipment. Others here could explain the CSI better than me, but that's it in a nutshell.

Plausible temperatures don't have very much effect. If the water is below 70 degrees, you should allow it to warm to room temperature before testing the CYA level. You should always test the FC, CC and PH shortly after getting the water sample while it is still at whatever temperature it started at. With very cold water you will need to mix the TA and CH tests more between drops, or risk missing a slightly delayed color change.

Whoops, must have misunderstood..:oops: I thought the OP was referring to why the Pool Calculator has a place for temp, hence the title of the thread.
