They work.
They work. Started a new 10 gallon tank with the EcoBio Block and cycled the tank. Never had an ammonia spike. Keeps water clear along with the Hygger HOB filter. Crystal clear water which we are all trying to achieve. Purigen packs in filter also help. Great combo.

Works perfectly!
Before having this magic stone, I had to change filter weekly ( filter was black and completely plugged by the end of 1 week) and water change bi-weekly. Now, the filter was clean after 1 week, and water perfectly clear by the end of 2 weeks. I have 6 good sized gold fish in each tank. thanks to this magic EcoBio-Block stone. This is THE single most efficient, and cheapest equipment for fish tank!!

Better than I thought it would be!
I was skeptical. I had tried everything the internet and the local fish stores said to do. Nothing worked. Added the Rock to the tank on 7/22. It took about a week before there was a massive difference but I could see a small one daily. Tank has been crystal clear for more than a week now. No chemicals. No water change. I did add a new bubble disc under the rock.

I haven’t noticed any difference for my tank so I can’t really say it helped or not
