Aqua Natural Substrates

All Aqua Natural gravel or substrates are 100% natural, sustainably sourced, triple washed and kiln dried. Our meticulously graded gravels and sands are the perfect natural substrates for any aquarium including planted tanks. Our high quality products create natural beauty combined with large surface areas for beneficial bacteria colonies and easy cleaning.

Nitrifying Bacteria

Pack contains bio activated live nitrifying bacteria to either use as a primary substrate or mix with substrate for a healthy aquarium. Contains a patented blend of live nitrosomas and nitrobacter bacteria which break down and convert harmful ammonia, into nitrates.

Directions for use:

PRIMARY (not mixed with Dry Substrate)

Usage Calculator: Use 1lb (450g) of Bio-Substrate for every 1 gallons (3.8 litres) of water.

• DO NOT rinse before use.

• Spread substrate and fill with water slowly. Avoid stirring up the substrate.

• Once the tank is filled, start your filter. Any cloudy appearance should clear over time.

MIXED (mixed with Dry Substrate)

Usage Calculator: Use 1lb (450g) of mixed LIVE Bio-Substrate and DRY Substrate for every 1 gallons (3.8 litres) of water. Mixing ratio is 1:4 (1 LIVE to 4 DRY).

• Mix Bio-Substrate and Dry Substrate thoroughly.

• Now spread mixed substrate and fill with water slowly. Avoid stirring up the substrate.

It's his favorite toy
This duck is his favorite toy. He takes his "duck baby" up to bed with him every night. It's held up to his love well. This is his second duck as the one we received as a gift 2 years ago is still alive and well just very dirty and in need of a stand in when his time comes. Over all Rico is quite happy with Duck and would give 5 barks.

Sturdy rope

Very sturdy rope. My dog is a heavy chewer and this rope is perfect for her.

This is the one for my dog, (and maybe yours)
Size: Medium (23.60")
Great dog toy! Got the larger size— less accidental hand bites that way. It’s our second one, but the pup is a strong chewer so no disappointments with the product at all. Many breeds would not do what mine did to the rope. I love that it’s natural cotton. The longer version that I ordered comes with 3 knots, including one near each end— great— and one in the middle, which I don’t like or need. It’s a tad difficult to untie the central knot, but it’s possible with a screw driver or awl, and then it’s a perfect toy.

Does not fray.
Size: Medium (23.60")
My 70# poodle loves playing with it. She throws it in the air and catches it and brings it to me and I throw it or I tug with her. It’s very sturdy.
