    I use PFS, have for a while, and there are worse things than paying $0.80/lb.
    I've been looking through alternative substrates available locally, and I'm a little lost. I have a properly sized (20-40) Coal Slag product available, but the MSDS http://www.tccmaterials.com/pdf/TCCblackblastmsds.pdf lists a bunch of metals. The more expensive one is 35 grit https://ca.brockwhite.com/userfiles...23-sand-blast-abrasive-2015_september_sds.pdf and says Stable/Insoluble. Otherwise I could go with a PFS sized 10-20, or a Pure Silica Sand sized 20-30. All of these are 0.25-0.35/lb. Does anyone with experience with these have any suggestions?

    I use BDBS in all but 1 aquarium. The 1 has pool filter sand. Both are good.

    BDBS is $8.00 for 50 lb. pool filter sand is $12.00 for 50 lb.

    Not sure how that translates to Canada.

    I wouldn't use the pure silica. Silicates tent to over produce diatoms...which most people refer to as brown algae.

    Silica sand doesn't "produce" anything, it's inert. It does need agitation (like any other fine substrate) to avoid problems, but diatoms are not high on that list. My question regarding the silica sands were about the sizing, as I have a lot of catfish.

    Black Diamond brand isn't available here. I pay over $40 for 50lbs of 20-40 PFS.
