Product Disclaimer:

Please note that all our products are custom-made, and the product images shown are examples of what you will receive. Due to the unique nature of each item, slight variations in color, shape, or size may occur.

In the event that your package or product is damaged during shipping, please notify us immediately. Be sure to include clear photos of the shipping box and the product damage so we can assist you with a resolution as quickly as possible.

Do I need to cure or soak it?

No. This is dry MarcoRocks, and MarcoRocks state their rock is reef safe straight out of the box. A light rinse under running water to knock off shipping dust is all it needs, and even that is optional.

Curing is a step that applies to two other things, not to this. Wild live rock has to be cured because organisms that died in transit need to break down first. Cement-based artificial rock has to be cured because it can leach into your water until it neutralizes. Ours is neither: it is natural calcium carbonate with no chemicals or additives.

Cycling is a different thing and it does still apply. Cycling is establishing the bacteria that process fish waste, and every new tank goes through it whatever rock you use. Adding a piece to a tank that is already established will not restart it.

Shipping & Turnaround

Ready-made pieces ship in 12 to 14 business days, nationwide to your door, and tracking is emailed to you when your order leaves the studio.

Custom builds do not have a fixed turnaround. It depends on the size of the piece and what is already in the queue, so we give you a real timeline once the design is settled rather than a guess up front.

Large sculpted scapes have real height and joints and can be fragile in transit, so depending on where you are we can hand-deliver to a nearby reef show, arrange local pickup in Pennsylvania, or offer on-site delivery and setup. We confirm the best option with you before you pay.

In plain English

New to this? A "frag" is a small cutting taken from a larger coral. It is how most reef keepers buy, trade and grow their corals.

This is where those cuttings live. It holds five to six frags and sticks to your tank wall with a magnet, so you can slide a coral higher for more light or lower for less, then move it again as it grows. The alternative is gluing coral straight onto your main rockwork, which is very hard to undo later without breaking the coral or the scape.

Because it is real reef rock rather than a plastic rack, it disappears into your aquascape instead of sitting there looking like equipment. Best for anyone actively collecting or trading frags.
