The arches arrived quickly and look exactly like real reef rock. My tank has been stable for months now, and the coral is thriving. No pests, no issues with water chemistry. A great addition to my reef setup.
James Watson –
I was worried about using rocks that harm natural reefs, but these are clearly made sustainably. The size and shape are perfect for creating natural-looking caves and overhangs in my tank.
Lisa Rutherford –
The rocks are sturdy and hold up well in the water. I’ve had them for three months and haven’t seen any degradation. The only thing I wish was a bit more variety in shapes, but overall very satisfied.
Evan Murray –
Great quality and environmentally friendly. The bacteria growth is visible in my tank, and the water parameters have stayed balanced. Highly recommend for reef keepers.
