"...my tank is pretty full. It looks great. Water is clear. All ammonia, nitrate, and nitrite levels are non existent now...
 I have not lost a fish since the block has been in there. I do not have to do water changes anymore. Very nice job creating this. I wish more people would read this and try it for themselves. I'm sure everyone would be pleasantly surprised.
Thank you for making this hobby a little easier!"

Clear Water - Healthy Fish!
Make Aquarium Care Easy with EcoBio-Block 

Reduce aquarium care significantly with easy-to-use EcoBio-Block Family Products. Clarify cloudy aquarium water and keep it clear and healthy.
Beneficial bacteria in volcanic block multiply for years continually improving water quality.



Aquarium water stays clear and odor-free for years with EcoBio-Block, a unique volcanic mixture infused with live beneficial bacteria that degrades organic matter, naturally creating a healthy ecosystem for fish and reducing aquarium care and maintenance.

Why do 80% of all those who start an aquarium hobby quit within 2 years? Until now, aquarium care took a lot of work. To keep the water in the tank clear, most people change 20-30% of their water every week or two. Fish-keeping isn’t much fun if you can’t see your fish!

Everyone loves having a beautiful aquarium, but it’s discouraging to have the extra burden of keeping fish on top of a job or school and/or housework. EcoBio-Block changes all of that. By dramatically reducing the need for changing water and vacuuming gravel, EcoBio-Block really makes this hobby fun! Even the experienced pro will appreciate EcoBio-Block’s exceptional performance in clarifying cloudy water. The water really becomes crystal clear.

In-house test

Water test result with EcoBio-Block after 1.5 years
Our test tank (20 gallons, containing 12 fish and one EcoBio-Rock) shows water condition after 1.5 year with an EcoBio-Rock.  Mineral-rich volcanic rock gradually leaches needed calcium and trace minerals into water. Fish are healthy and water is clear.
Test strips from left to right show:  ammonia levels at zero, nitrite levels at zero and nitrate levels at near zero.
