Well I've taken the plunge and ordered the K-2006 Test Kit here in Canada. OUCH on the price, but moving forward . . . I will be using the BBB method from here on.
But I have a question regarding the Pool Calculator. Even though the volume of water can be entered in the "Size" field, do the calculations apply the same to pools and spas? I'm just wondering if the calculator would apply to my spa. The reason I ask is that I notice on my test strips there are different ranges for spa vs pool. I have already played with the Pool Calculator using the suggest goal levels from TroubleFreePool.com. However, I just picked up a very cheap test kit just for FC and PH. The scale for the FC in this kit is 0.3 to 3.0 with 1.0 showing as ideal. But again, the kit does not specific pool or spa. Just want to make sure I'm applying the proper target levels.
