Fair warning - it definitely smells, but that’s clearly part of the process! It’s done exactly what it’s meant to do and appears to have worked really well in my tank. Easy to use and effective, so I’d happily buy it again despite the smell.

The smell is terrible. Sulphate. But didn't effect my reef . Seems a good product

Very good product - found it more effective than products shown on YouTube. Helped to reduce the smell coming out from the sump as well as re-establish bacterial colony after a dino outbreak.

Very good. Fish love it. But the smell isn't great

Yes does what it says thank you

Not used as yet, but this looks like a great product, I am sure I will get good results. Update...been using regularly now and it's doing it's job. It Absolutely stinks! So keep in a zip lock bag for storage. Doesn't bother me personally as the smell tells me it is a natural product, but it does pong!

First of all, it stinks, badly. But seems to be doing great job. Used together with Nite Out II and my ammonia dropped to 0ppm within 12 hours, so the nitrites. Water is clear, and I've noticed the brown algae has reduced a bit too. I am very pleased with the product, a must-buy for fresh aquariums.

We struggled with very high level of Nitrate and Nitrite in our new fish tank, 25% water changing weekly did not help so we were looking to find a solution to address this problem, after searching the internet we found this produce and we decided to give it a try, after 2 applications, both Nitrate and Nitrite reading has come down to normal/safe level. We are very happy with this stage of our tank environment, we highly recommend this product to everyone who has same issue in fish tank as us. Great product!
