Customer Reviews
Good rocks, easy to use
I got some Key Largo Dry Rock for my new tank and it was perfect. Came packaged well, nothing was broken. It was easy to stack up and make a nice scape. My fish love it already.
Smooth order, fast delivery
My recent purchase of the Reef Saver Rock and an Aquascape Mortar Kit went very smoothly. The ordering process on the website was straightforward. I received email updates throughout, and the package arrived in about 6 days to my address in California, well within the estimated timeframe. The rocks were securely packed and showed no signs of damage upon arrival. The mortar kit was also complete. I appreciated the careful packaging, which really minimized any risk of breakage with such delicate items.
Great value on the starter pack
I was setting up my first reef tank and needed a good amount of rock without spending a fortune. I found the Dry Rock Starter Pack here, and it was a really good deal compared to other places I checked. The free shipping on my order helped a lot too, saving me even more. The rocks I got were a decent variety for the price. It felt like a solid investment for starting out, especially with the costs of everything else for a new tank.
MarcoRocks Community Discussion
Share tips, ask questions & help fellow shoppers save more
Is MarcoRocks actually pest-free like they say? Don't want any hitchhikers in my new tank.
Are their Black Friday deals actually good, or just a few bucks off? Thinking of waiting for it.
Does anyone know if MarcoRocks does a military discount? My buddy was asking.
Anybody compare MacroRocks to Real Reef Rock? Trying to decide for my new 75 gallon. Leaning towards Marco but wanna hear experiences.
What's the deal with returns if I order a bunch of rock and some pieces aren't what I expected? Is it a pain?
