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
The smaller version of our Original Magnetic Frag Rock. A "frag" is a small cutting taken from a larger coral, and this is a place to mount a couple of them.
It magnets to the tank wall, so you can raise or lower a coral to dial in its light and flow without gluing it permanently to your rockwork. Good for a nano tank, for a first magnetic mount, or as a second spot alongside the large one.
