    Has anybody used Nepheline syenite on aquariums? Is it safe to use as a substrate?

    Once washed thoroughly, can I add it without it affecting my cycling process?

    Also, should I run the canister filter while the sand is settling? will it ruin the filter?

    It is also known as Barium Sulfate...Quartz. In it's pure form it is fine as a substrate. Do not run the canister filter while adding sand and stir the surface well to get any floating sand to settle before turning filter back on.
