Aquarium Ocean Dry Reef Rock 20kg (18-30cm Pieces)

Had to smash up some rock as they were huge pieces really good quality will be using again

So, this is artificial reef rock, in the sense that it's limestone chunks shaped (naturally) to look like reef rocks. Okay to use as base rock/to bulk up the amount of rock in your tank, but it's not as porous, and therefore not as useful for filtration.It's good for use in supplementation for actual reef rock though, and you get a lot of rock (very large pieces) for your buck, I was pleasantly surprised! One piece was extremely large, but if you can't use pieces that big, it could be broken in half and made smaller.Summary: not reef rock per se, but fantastic for what it is, good value for money.

Absolutely perfect rocks just what we needed for the aquarium delivered today no problem at all kept updated throughout the process thank you ☺️
