3 Ways to use Sub Stratum:

  • As a sole substrate
  • As a drainage layer
  • Mixed in with other substrates

Sole Substrate

When Exo Terra's Sub Stratum is used as the sole substrate, add a layer of 2,5 - 5 cm (1 - 2 in) to the terrarium. The live bacteria will activate when the substrate comes in contact with water or waste. The organic matter such as left over food and animal waste will decompose over time. The absorbing properties of volcanic ash will eliminate odours by trapping the decomposed materials. Rinse the Sub Stratum and replace partly every 12 months.

Drainage Layer 

Add a top layer of biological substrate to the Exo Terra's Sub Stratum layer for optimal bioactivity and drainage. Plants can be secured in the top layer (eg. Exo Terra's Plantation Soil) while their roots will thrive in the sub layer of Sub Stratum - resulting in optimal growth.

Additionally, an inorganic layer can be added first for even better drainage (Exo Terra's BioDrain) to allow excess water to flow through the substrate to avoid saturation and anaerobic bacteria to outcompete the beneficial bacteria in the Sub Stratum substrate. Use the BioDrain Mesh to separate the BioDrain layer from organic matter to penetrate the underlying layer.

Use a top layer of leaf litter to provide dry areas, shelter and dwelling surfaces for all organisms in the terrarium. In the meantime it will prevent evaporation of the underlying layers.

Mixed-in

The secret to growing healthy plants begins with the soil. Naturally, healthy soil contains living microorganisms — from bacteria to fungi, protozoa and arthropods. Together they form a choreographed exchange from the recycling of nutrients to the decomposition of organic materials.

By mixing the Sub Stratum with other organic substrates, you enrich any substrate with the required minerals like calcium, nitrogen, potassium and phosphorus. It also aids in the water retention capacity and provide adequate air supply to the roots.

Only use tap water treated with Aquatize (PT1979) in bioactive planted terrariums to remove heavy metals, chlorine, and chloramines.

The regular use of Turtle Clean (PT1998 or PT1999) to add extra beneficial organisms to the terrarium water will support the biological filtration capabilities.

  • Natural bioactive soil
  • With live beneficial bacteria

Good quality dog ball for playing fetch
Size: Medium
My dog and family love these chuck it balls to play fetch with our dog. They are durable and fun. They squeak which is added fun for any dog! Regular tennis balls my dog chews apart and they get pretty gross after playing and being left outside. These can be easily washed off and cleaned. These balls last! Would recommend to anyone with a dog and would purchase again.

Picky dog approved!
Color: S6-muti-color, Color: S6-muti-color
I have wasted so much money on dog balls that they won't even pick up! They finally were obsessed with the Kong rubber green/blue or red/blue ones, but they're $3+. each, and they break from the dogs squishing it. I honestly had zero expectations on these, and they BOTH picked them up on the first throw! That's huge!! Seem to work fine in the ChuckIt. As for the squeaker, at first I was like "Oh nooooo." when they both loudly started! Much to my (and my neighbors') happiness, the squeakers stopped working after a couple minutes. 🤣

The balls are great for chewers. The squeaky didn’t last long but they are perfect for the ball launcher.
