Good product
Good stuff, no clouding of water did not rinse, yet to test water as cycling. Added water slowly with cup in bottom of tank to minimise disrupting it, plants seem happy (they were browning when first purchased now green)

Not just for fish also can be used for plants and corms
Does what it says on the description, and also for plants (not just fish tank plants.) Bought this flurval stratum for the plants as Mrs wanted some for her alocasia corms when re sprouting them -worked a treat! And bonus not too expensive and easy to store and use.

Great substrate
Love this for my planted 105L tank, used about 1.5 bags, didn't get no clouding and i didnt even rinse it but I added water very slowly to the tank. Plants seem to be thriving.

Good for plants

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
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

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.

Great aquarium substrate
Great substrate for my new aquarium - washed before putting it in and took about 6 or so hours to settle, but really happy with it
