I'm looking to use black gravel in my planted tank...has anyone heard of or used Black coal aquarium substrate (10kg, £13.99 from aquaessentials)...is it good to use.
My guru gf225 *blush blush* mentioned black quartz gravel but its 50 quid for 25kg...ouch! Is the above similar to what you suggested George?
Many Thanks Sam
