Black Gravel

[LIL860]

I am looking to buy a Fluval Roma 200 and would like to use black gravel in it. Which is the best brand to get as ive read that some types of gravel can affect PH and i dont want it to do this. Thanks

I just used some Unipac. Ph increased for a few days when it as added then came down. Not sure if it was the gravel that caused it.
 
Incidentally, although it looks black when dry, it is actually black with some brown mix when under aquarium light. I wasn't sure I liked it at first, cos my oher tank was done with Marina which is very black. But the black wth brown specs actually looks better
