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 1-2" (2,5 - 5 cm) 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.
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.

Reassuring to use an operator with tracked named-day delivery, exactly what you want when dealing with glass aquariums. Great range, great prices.

24hr delivery of a pallet, for a complete marine aquarium. And two days before Christmas. No picking errors, best pricing and then great service with hour slot from UPN Pallet Network. Impressive!

Nice searchable website, plenty of stock, reasonably priced next day delivery, well packaged. Slightly more detail would have been nice as I bought 32mm thinking that was the external diameter but I suspect most people buying these items would know that. :)

This was actually my first time ordering something from them wasn’t sure on how long I would get it said two days, but literally I ordered it and it came the next day. Packaging was amazing.

Such a great service. Bought a fish tank Ciano emotions 150 Pro and it's arrived very well packed just 2 days after purchase. After 2 weeks i had an issue with light power supply which has been replaced straight away after I reported that to customer service. They look afyer customers and always replied very quickly if you have any problem. Strongly recommended!!!
