This is my second purchase of this for substrate in a 55 gallon aquarium! So affordable, I fill a 5 gallon bucket about 4 inches from the top and let water rinse throughout until water is clear and no longer showing any film on top, then I place it into the tank with a scoop. 1 bag was enough and it looks so good!

Seen reviews on this for tanks after using it in our gunsmithing shop for sandblasting firearms prior to painting. We use the red fine grit for the sandblaster and the black label medium grit for the tank substrate. Both work great and are SOOOOO MUCH MORE AFFORDABLE than other options. Definitely more bang for your buck in both scenarios!

I’m not even gonna lie when I got my 75-gallon fish tank for Christmas from my brother, I panicked. Not because I don’t know what I’m doing (I’ve been in the fish-keeping hobby for 6–7 years), but because bigger tanks = bigger setup costs, and my wallet immediately felt threatened. After doing an unreasonable amount of research (aka doom-scrolling aquarium TikTok and YouTube), I found out this black sand is actually a solid choice for aquariums. You do need to rinse it first skip that step and your tank will look like you unlocked the “fog of war” feature. But once it’s rinsed, it’s smooth sailing. I bought 100 lbs for my 75-gallon tank, and yeah… that was plenty. I got a clean slope going with about 4–5 inches in the back and around 3 inches in the front. Reminder: a 75-gallon tank is 4 feet long, so this sand really showed up and did its job. Overall, I’m obsessed with how it looks. The tank looks clean, the contrast is elite, and most importantly my fish are thriving no stress, no weird behavior, just vibes. For the price, this sand absolutely ate and left no crumbs.

This product should be labeled Xtra course due to the difference of the fine grade. I find that it consistently plugs up the nozzle even though I was using the largest nozzle available.
