Definitely has beneficial bacteria! A day after adding there was a bacteria bloom! Cleared up the next day😊 I love the color as well, it's black but it has a hint of green specs in it. Overall its exactly as described.👍

Used for a larger tank for my Betta. I haven't put him in there yet but I just put it in planted it and it wasn't cloudy. Looks great, capped it with gravel

The plants in my 5 gallon betta tank love the CaribSea Eco complete. But it shows every piece of dirt and gets dirty easily. My solution, a cap of Betta Bio-Activ Gravel.
It looks amazing and solves both problems.
The betta is a Red Samurai.

This stuff is great for starting a tank.

I added this bio sand to a new 10g set up. It also added a nice contrast to my more natural pebble substrate. The initial “ cycling” went fairly smoothly but still holding off on fish. Some LFS ghost shrimp are enjoying first! Thank you AC . Love doing biz with this company!

Added two bags of this to a 10 gallon to help jumpstart the cycle (dark area in the substrate). Has definitely helped with that! Water tests have all come back with a 0/0/0. Definitely recommend for any aquarium starting out

This s good product, thanks like always

This product is "live" and comes packed in water, presumably with a microbial ecosystem within it. That said, the gravel is a smaller amount than you might think, perhaps a cup in total. Even for a small tank, you will certainly need additional substrate.

That said, the product worked wonders for inoculating my new aquarium. I used untreated RO water, and I had visible biofilm within days. This would never have happened so quickly with RO water alone.

My plants are thriving, and my nerite snail is grazing and happy. Highly recommended.

really excited to use this to set up my first tank, was a little sad that one of the bags came busted and leaked on all my stuff though

I really like this gravel. I did not need to rinse it before using it, which made setup much easier. Just to be safe, I kept my betta out of the tank for about an hour or a little longer after adding it.

I bought 3 bags for a 3-gallon tank, but honestly, I probably should have bought 4 or 5 bags if I wanted a fuller look. Still, it looks very natural and seems very safe for bettas. It gives the tank a clean, realistic appearance that I really like.

The new tank is about 6 weeks old and the plants appear to be thriving for the most part. However, I'd like to see the granules be larger (balls) to help the roots lock in better, yet remain easy to uproot to transfer if needed.

Is bioactive sand. Is good. Very good.

Excellent as usual

While I wouldn't say this instantly cycled my new tank, it definitely shaved a couple of weeks off the process. It also helped keep ammonia and nitrite levels from spiking or getting as crazy as they had been before adding the gravel.

The black color looks great in the tank, has an interesting amber sheen to it under the LED lights, and my Betta enjoys resting on it sometimes.

Nice and pretty substrate. Smaller grain than I was expecting but very pretty with plants, holds the roots really well!

Love that I do not have to rinse this stuff plus it isn’t messy to place unlike sand can be. This substrate is nice and fine but not as super fine like sand, but still soft. I love that it is bioactive and is helpful for cycling a new tank or preparing a hospitalized tank. Only wish it came in a bigger size

Absolutely love this product i have added it to all my tanks

Works as described, my hospital tank was pretty much instantly cycled with this stuff. Tested daily since adding and everything seems stable. These are extremely small packages of gravel, I probably should have ordered 6 instead of two.

This is my first time having a planted tank and so far my plants are LOVING this gravel

For my 5.5 gal betta tank, I got two bags of betta gravel which covered the bottom of my tank. Great cycle starters!

Looks great as a top gravel. Very nice black color that really brings out bettas’ colors

Package came on time and arrived well. I added it at the bottom of my tank before the sand and substrate and is doing really well. I haven’t added any fish yet but I’m sure my betta will love it.

well i believe in a good substrait. i dont skimp on money there. I plant my plants and then i put the gravel down. so the gravel is on top of the substrait. it works for me and more important the plants and fish thrive for me. Cory is a great aquarist and you should watch his videos on youtube

This worked great for my newly established Betta tank. Can get any easier than open bag and pour in. I added my Betta that same day. He's happy and I'm happy. I would recommend !
