I'm trying to figure out what is going on here. We had the plaster acid washed when we moved in to get rid of. Black algae. We had other repairs made including a rusty piece of rebar. It appears near the drain I'm getting black spots. Some are linear which makes me wonder if that is more rebar issues. The side walls have a yellow/grey type tint. You can see it is up and down like where the acid was poured and scrubbed. My neighbor gave me dry acid and told me to let it sink to the bottom in a sock to help get rid of it it. I havent had a chance to try it yet. This weekend.
My levels are always with in acceptable range. I keep the PH on the low end around 7.2 as it is always rising. FC I aim for 10 and dose 10% bleach and MA daily 8oz of each to keep everything in check.
Im not sure now to investigate or fix this.
Thoughts?
