Is sand ok for fresh water?
I am very confused. Today I tried to buy sand for my tank and the two different places I went to, both aquarium shops, told me that I cannot use sand in my fresh water aquarium. When I was about to buy the sand that I had chosen I was told that it would raise the ph of my water and that there was nothing I could do to fix it once this occurs.
I asked if there is a sand that I could use for fresh water and they said no (well one place said I could use 'fake' sand but neither carried it).
Can anyone confirm this for me? I was surprised because neither bag said anything on it about being strictly for saltwater, and one said that certain elements make raise to ph but to monitor it periodically with a test kit.
