Ive had my hot tub for about 10 months now. We initially used the chemicals that came with SPA. When they ran out, we changed the water and went BBB. My first issue was that I couldnt seem to keep FC in the tub. Numbers would be in spec in regards to FC/CYA, but after a quick soak or a few days of non use no FC was in the tub. I began running a higher FC but then the bleach smell was a bit noticable. Not very strong. But stronger than it was when I was using the spa chemicals. I started using a product called Spa Oxidizing Shock by Natural Chemistry. I'm under the impression this is shock with no chlorine, also called MPS. This has helped tremendously with FC swings. My question about this product is how do you properly use it with the BBB method. Follow instructions on bottle, or is their a better way to figure out what my doseage should be with this product. Right now Im pretty much just guessing.
My current problem is that the water seems to be a bit foamy when the jets are on high. Ive had this issue since switching to BBB. The water foams, but when you kill the jets, the foam goas away after 15- 30 seconds or so. Is there anything I can do to reduce the foam. I started to use the defoamer product I see in the pool stores, but I really want to avoid using any additional chemicals if I can.
I use Walmart 8.25% Bleach to chlorinate
