Review: Smells awful but works really well - 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.

## Questions & Answers

A: I don't keep it in the fridge been using it for over a year with no problems as long as it doesn't  get to hot. I believe keeping in the fridge does extend the shelf life.

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

### ⭐⭐⭐⭐⭐ Will use Arka bacteria from now on.
*by L***Z on 26 December 2025*

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.
