Review: great stuff! - I LOVED THIS. great value for money, plants grow well and the size of the stratum isnt huge. ive placed sand over mine, but it looks okay without sand too.
Review: recommend - Very good! Plants take root quickly and grow great. I recommend. The layer does not have to be thick and the price is very good. In stores I found the same product more expensive . Easy to use and safe for fish. Cover with another inert substrate.

### ⭐⭐⭐⭐⭐ A must for any aquarium
*by T***Y on 22 November 2025*

So wish I had made the change sooner, after years of using gravel then sand an back to gravel, I decided to bite the bullet an give it a try , WOW opened the bag poured straight into the aquarium an slowly filled with water added some tap safe an I think my baby plec is gonna love its new waters once its cycled an ready , really good value an will be buying more for when i upgrade to a larger tank , it looks very pleasing on the eye , was worried as other customers reviews were very mixed , i found the best way is to just open an dump it in i slowly filled the aquarium pouring into the filter chamber so it didnt disturb now just to sit back an start letting nature take its course, excuse the food bits on the bottom as starting an new cycle while my little guy is growing out , would definitely recommend, an the water looks clear an crisp should of used it sooner
