So, I've had this pool for a couple years now and never had much issue with the water. I've never tested my chemistry of my water before, until the other day I got a free test kit. I thought it would be interesting to experiment with. It tests FC, pH, and bromine.
The initial test revealed I had plenty of FC, somewhere between 2 and 3ppm. But the pH was a pale yellow reading below 6.8. So I went and got some pH up from the grocery store. (It was late and the pool supply was closed) I added a little and it turned dark green as mixed with the water. I didn't think much about it, because bromine does that too, but clears up quickly. This didn't and the pH didn't rise at all. So I added more and more. The pH never rose and I ended up with greenish water and some weird dust on the bottom.
Today, I took a water sample to the pool supply and he said the pH was VERY low. He gave me a bucket of soda ash, saying to add a few pounds at time, in increments of 4hrs, while keeping the pump running on low speed. Now my water is dark olive green. Not opaque or clowdy. Just Army green. I called him and told him about it and he said to just give it some time and get back to him. But in the mean time, does anyone know what I'm talking about?
I tested my tap water that I use to fill it. It checked out at 7.6
The pool as of now
pH is below range. If I had to guess I would say around 6.t
