Josh’s Frogs BioBedding Tropical Bioactive vs Zoo Med Excavator Clay Burrowing Substrate: Which Fits Your Dragon and Enclosure?

Josh's Frogs False Bottom is a bag of LECA expanded clay pebbles built to create a drainage layer in bioactive vivariums and terrariums. It is made for frog keepers, reptile owners and plant lovers who run misted or high humidity enclosures with live plants.

In use, the pebbles trap excess water below the soil line so roots stay aerated while evaporation steadily raises humidity. This setup helps prevent soggy substrate, supports healthy plant growth and creates a more stable home for cleanup crews like isopods and springtails.

The pebbles are lightweight, uniform and porous, so they pour easily and stack with plenty of air gaps for water flow. The clay material is tough and long lasting, and it can be rinsed and reused through multiple builds.

The main limitation is coverage, since larger tanks will need more than one bag for a deep drainage layer. You will also want to rinse off dust before setup and use a mesh barrier on top to keep fine substrate from falling through.

Overall, this is a simple, effective foundation for any bioactive terrarium. If you want cleaner water management, healthier roots and better humidity control, this LECA layer is an easy win.

Brand: Josh's Frogs, Part Number: JF00516, Form: Expanded clay granules.

Volume: 4 Quarts, Use: Vivarium false bottom and drainage layer.

Best for: Bioactive terrariums, automatically misted vivariums, live plants and frogs.

Josh's Frogs ABG Mix is a premade bioactive terrarium substrate based on the original Atlanta Botanical Garden formula. It is made for tropical vivarium keepers, crested gecko and tree frog owners, dart frog hobbyists, and anyone growing live tropical plants indoors.

Performance in real tanks is where it stands out. It holds humidity high and steady while still draining freely, so plants stay hydrated without waterlogged roots. Users report thriving plants, active springtails, and healthy isopod populations with less frequent spot cleaning.

The blend combines charcoal, milled sphagnum moss, pine bark, tree fern fiber, and peat for balanced texture and airflow. It feels light, earthy and clean, with good structure for burrowing microfauna and root development. It also breaks down slowly for long term use.

There are minor prep steps to know. The ingredients ship layered in the bag, so you need to dump it in a bucket and mix fully before use. It is dusty when dry, so pre moistening with distilled or reverse osmosis water makes handling much easier.

For anyone wanting a proven, vivarium ready substrate without DIY mixing, this is an easy recommendation. It is consistent, plant friendly, cleanup crew friendly, and ideal for tropical bioactive setups.

Brand: Josh's Frogs, Model Number JF00504, Style: Tropical. Product type: Bioactive terrarium and vivarium substrate.

Volume: 4 quarts, 1 gallon, 128 ounces. Ingredients: Charcoal, milled sphagnum moss, pine bark, tree fern, and peat.

Best for: Tropical terrariums, dart frog vivariums, crested gecko enclosures, tree frogs, live plants, springtails and isopods.

Empty the full bag into a large bucket or tote and mix thoroughly to blend the settled layers. This step ensures even moisture retention and drainage throughout the enclosure.

Lightly moisten with distilled or reverse osmosis water until evenly damp but not dripping. Spread over a drainage layer and barrier if using a bioactive vivarium, then add plants and leaf litter.

Add springtails and isopods after planting to establish the cleanup crew. Maintain humidity with regular misting and monitor soil moisture to keep it damp, not saturated.

Josh's Frogs BioBedding Tropical is a ready to use bioactive substrate designed for high humidity enclosures. It is made for crested geckos, day geckos, chameleons, tree frogs, water dragons, tropical snakes, anoles and tarantulas.

Paired with springtails and isopods, it creates a self sustaining cycle that breaks down waste and keeps the enclosure cleaner. Users report it stays moist without turning rotten, dries out naturally, and supports burrowing, tunneling and egg laying.

The blend combines organic and inorganic ingredients with trace elements, charcoal and beneficial fungi. This structure resists compaction, improves airflow, holds humidity, and gives live plants a healthy base to root and grow.

It is not a fit for every situation. It is formulated only for tropical setups, so desert species need a different mix, and it is not recommended for quarantine enclosures where mites could be a concern. For best results, you will also want a false bottom for drainage plus added microfauna.

For keepers building a naturalistic tropical vivarium, this is a reliable and low maintenance foundation. It looks natural, supports plants and microfauna, and lets pets dig and explore comfortably.

The Zoo Med Excavator Clay Burrowing Substrate is a moldable clay substrate designed for desert and burrowing reptiles. It is made for keepers who want more than flat bedding and prefer an interactive habitat where pets can dig, tunnel and nest.

In real use, you mix the clay with water, sculpt tunnels, hills and terraces, then let it dry to set. Once cured, burrows hold their shape without collapsing, so leopard geckos, bearded dragons and similar species can exhibit natural digging behavior safely.

The formula is all natural with no added dyes, colors or chemicals, which helps create a clean and authentic desert look. The texture packs firmly yet retains a natural earth feel, and this 10 pound 2-pack format covers larger tanks or allows for deeper substrate layers.

It does take some prep work, since mixing, shaping and full drying requires time and planning. Once hardened, it is heavier than sand or fiber bedding and spot cleaning takes more effort, so it suits arid species better than tropical ones.

Overall, this is an excellent choice for reptile owners focused on enrichment and naturalistic setups. If you want stable tunnels, creative landscaping and a safe clay habitat, this substrate delivers strong results.

Brand: Zoo Med, Model Name: Pet Supply Zoomed Excavator Clay Burrow Substrate, Model Number: XR10.

Size: 10 pounds per bag, Pack of 2 for expanded coverage and deeper burrowing layers.

Material: Natural excavator clay with no added dyes, colors or chemicals for reptile safety.

Best Use: Active burrowing reptiles and arid terrarium setups requiring stable tunnels and sculpted terrain.

Zoo Med Excavator Clay Burrowing Substrate is a moldable clay bedding designed for desert reptiles that dig and burrow. It is made for bearded dragons, uromastyx and other burrowing species, plus keepers using it for tarantulas.

When mixed with water and shaped, it dries into firm tunnels, caves and hills that stay in place. Owners report bearded dragons digging for long periods and uromastyx creating their own side tunnels that hold shape for months.

The 20 pound bag provides generous coverage for full terrarium builds or custom structures. The unscented clay texture feels natural underfoot and blends well with other substrates when you want a looser dig area.

It is not a pour and go bedding, as success depends on getting the water ratio right. Too wet and it falls apart, too dry and it crumbles into loose piles and hard balls instead of solid tunnels.

For keepers wanting natural enrichment and realistic desert landscapes, this is a top choice. With patience during setup, it rewards you with a durable, burrow ready habitat your reptile will actually use.

Brand: Zoo Med, Model Number 26406 for reptile terrariums. Package Size: 20 lb bag designed for building burrows, tunnels and desert landscapes.

Pet Type: Reptile, including bearded dragons, uromastyx and other burrowing species. Also commonly used by tarantula keepers for naturalistic enclosures.

Material Type: Moldable clay substrate, unscented form. Add water to shape, then allow to dry fully to create hardened structures.

Zoo Med ReptiSand in Desert White is a 10 pound natural sand substrate made for desert terrariums. It is designed for keepers of bearded dragons, sand boas, soft shell turtles and similar arid species.

The sand is all natural with no dyes or colors added, so you get a clean, bright look. It stimulates digging and burrowing while conducting heat well for basking spots under overhead lamps.

The grain size is fine enough for easy digging yet looks naturalistic in display tanks. The Desert White color brightens the enclosure and makes waste easier to spot for daily cleaning.

Like all loose substrates, it needs regular spot cleaning and full changes to prevent odor and bacteria. It is best for healthy adult desert reptiles, as very young animals that lick or ingest sand need extra supervision.

For desert reptile owners who want a simple, natural and attractive substrate, ReptiSand is a proven choice. It balances looks, function and comfort while supporting instinctive reptile behavior.

Brand: Zoo Med, Product: ReptiSand Desert White Sand Substrate

Size: 10 lb bag, Dimensions: 11 x 6 x 2.5 inches

Color: Desert White, Material: All natural sand with no dyes added

Best For: Bearded dragons, sand boas, soft shell turtles and other desert reptiles

Use a deep enough layer to allow digging, typically 2 to 3 inches for most desert species. Position the basking lamp to warm the surface and check temps with a thermometer.

Spot clean daily and replace soiled sand to keep the habitat fresh and odor free. Always provide fresh water and monitor your reptile for excess ingestion.

Wash hands after handling substrate and supervise new animals during the first weeks on sand. Consult a reptile vet if you keep hatchlings or recovering animals.
