Aqua Natural Bio Substrate and Dry Substrate kit for New and existing Aquariums, Diamond Black, BIOKIT004

Didn't seem to speed up cycling a 75 gallon tank much but like the substrate

A year later and it still looks great. I capped this off with some white sand too. It looks clean and it didn't make the water cloudy.

I'm thoroughly impressed with Aqua Natural’s Bio and Dry Substrate! It looks beautiful in my aquarium, is easy to set up, and promotes excellent water clarity. My plants are thriving, and my fish seem happier than ever. The substrate provides a stable environment, supports beneficial bacteria growth, and maintains water parameters effectively. Definitely a top-quality product—perfect for anyone serious about creating a healthy, attractive aquarium environment.

Beautiful substrate. Looks like a real river bed.

I received the black sand and bio substrate was frozen. Did this kill live bios? Used the black sand in another tank great starting a new tank .

Looks great in my fish tank and was easy to add. No mess the bag was perfect size for me.

The media could not be loaded. This substrate is excellent! I DO recommend rinsing the dry substrate several times before mixing with the bioactive substrate though, because it leaches black die/dust particles and will cloud up your tank. Do NOT rinse the bioactive substrate. After rinsing the dry, i mixed the substrates per directions and placed in the bottom of an empty aquarium. I added my plants and used my fluval C2 filter from my existing 10gal tank to improve the speed of the cycle (already had bacteria in it to help break down the nitrites and ammonia). I also added some Flourish fertilizer to aid the plants. After about a week, I added the driftwood (after rinsing and boiling many times) and cycled another couple of days. I tested the water everyday throughout the cycling to monitor nitrates, nitrites, and pH levels. After a total of 9 days from start to finish, my tank water was perfectly cycled and ready for fish. As you can see in the picture, everyone is happy and healthy and my tank is beautiful!

Excellent
