Hey guys, I got a few rocks from my river/stream near my house, We don't really live near a city so our streams are pretty clean.
Anyway, I've cleaned them up, Poured boiling water over them and done a vinegar test with no fizzy stuff or anything like that. There all round and grey/black ish, No strange or our of place colours.
With all that, do you think its safe to put in the fish tank? I've seen local people do it before with no effect, Maybe a slight rise of PH but thats typical of rocks.
