Do I need to cure or soak it?
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
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
Rubble is small broken pieces of reef rock, and it is a working material rather than decoration.
Most of it goes out of sight. In a sump or refugium, all those nooks give filter bacteria surface area to colonize and give copepods, the tiny crustaceans that feed fish and corals, somewhere safe to breed. It is also handy as small bases for gluing coral cuttings onto, and for filling awkward gaps and hiding joints in a scape.
One honest note: rubble traps detritus, so give it a rinse now and then rather than installing it and forgetting it.
