Hey bud, I have a question that maybe your wonderful sister could answer for me. Do you remember me talking about the Calcium Carbonate sand? Well, with the help of your sister we figured out that the calcium would precipitate first, and it did, my Ca readings are now 1200+.
The main thing I want to know is why is the sand turning black towards the bottom of the sand bed? Right now it's just a small 4 inch long patch and it's not totally black but it's getting there. It also appears to be reaching further towards the surface.
I appreciate your help.
