OK.... long time fish keeper here, first shrimp tank. I know I am probably just over thinking everything. I really thought I understood but, now not so much.
So here is my Q: I decided to purchase RO water from my LFS. They informed me that they re-mineralize there. So after collecting all my plants and rocks, moss etc... I get home with my RO water and begin to test it. My TDS meter reads it at 600. My GH is at 8 but my KH is over 22 ppm. Ph is 6.4 . Now, at the same time I have an aqua scape tank same size 10G, for this tank I purchased distilled water for the initial set up. Here my TDS meter reads at 144 GH is 6 and KH is 3. I am soooo confused. Answer me this... did they over re-mineralize the RO water. At first I thought maybe they gave me the wrong RO water (marine) but, they know me and know what I am doing. I'm certain he gave me the correct water. Can anyone help me understand this and, maybe I should just be using distilled water. IDK like I said this is first attempt at setting up a shrimp tank.
