So it's been almost two weeks since my hammers started looking like this. It's weird because they were good in the afternoon and by the evening they started looking like this. What could have happened?? Tested water. Parameters checked out on point. I did scrub some gha off the rocks with a toothbrush earlier in the day. So I don't know if that could have had anything to do with it.
