What's next?
I'm testing CRS in low pH. To see if the low pH will alter ... well, anything.
pH is about 5.5.
So far ... I'm not sure if it's my imagination ... but whites seem whiter, and I'm noticing more Pretty Legs, where they used to be plain before (I think). I can't be sure cause I have too many shrimp in the tank, so it's not like I see one shrimp change. Instead I see many shrimp, but the general impression is more pretty legs colouring up.
I'm continuing to adjust this RO remineralising mix a bit more ... who knows, maybe I'll release it for sale.
