  • Great product
Color: Bio-Stratum Size: 8.8 Pound (Pack of 1) Style: Substrate
I didn’t rise before because I wanted to keep all that good stuff. I did let it cycle for about 2 hours before I put my betta back in his tank.

  • Great product and price
Color: Bio-Stratum Size: 8.8 Pound (Pack of 1) Style: Substrate
Great price! It was half the price as it was for me to buy it at Petsmart. They worked great in our aquarium and terrarium. We used them mail y for our bio habitat.

  • Annoying to plant in, but does grow plants well
Color: Bio-Stratum Size: 8.8 Pound (Pack of 1) Style: Substrate
Plant’s grew wonderfully, but annoying to plant in because of the size of the substrate. Roots let loose, even with a sand layer on top. Still, roots showing or not, my 5g is flourishing with plants.

  • Great for plants!
Color: Bio-Stratum Size: 8.8 Pound (Pack of 1) Style: Substrate
I've always used Fluval Stratum in a semihydro setup for propping/ rooting plants of all kinds (philodendron, pothos, monstera, but especially alocasia corms). This blue label is more dusty than the red label, though, so I am trying to stick with the red label. Definitely the only Stratum brand I'll ever buy ... show more
