Im getting all kinds of micro bubbles from my pumps now too.** A: Yes. It's the initial bacteria die off that causes that. You should rinse the rock thoroughly in RODI water before adding to your tank to avoid this. **Q: Is there a wide variety of sizes and shapes among the rocks?** A: Yes and you can always break bigger pieces **Q: Is this rock or sand??? Description and title are conflicting** A: Supposed to be the rock. I had ordered it and ended up with 40 lbs of sand, told Amazon about it and they fixes the issue and sent me the rock **Q: Since this is not natural live rock how is it cultured to get the coraline algae?** A: Real aragonitic base rock with live spored bacteria, shipped dry. At an unprecedented 50% void space (macro and micro), you will be hard pressed to find a durable natural rock that has this magnitude of porosity. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great product *by M***E on January 19, 2026* Great assortment of rocks package arrived great and looks good in my aquarium. ### ⭐⭐⭐⭐⭐ PERFECT !!!!

There was a large variety of sizes and shapes in my box, all with lots of nooks and crannies which will be great for future inhabitants! I will say that several pieces had chunks broken off them from shipping, but considering the volume and weight of this package, it doesn’t surprise me. I can’t complain. The rocks still look great in my tank. I already had a decent bit of rock in my 55 gallon newly set up tank, as I transferred some live rock to it from my 32 gallon Biocube. So not all of this shown in my tank is from my shipment. That being said, I had four pieces leftover after arranging in my 55 gallon tank, one of which was very large, and I put those four into my biocube. The rock shown laid out on the table on the newspaper all came in my order. Beautifully colored pieces! ## Frequently Bought Together - Caribsea Life Rock, 40-Pound - Instant Ocean Sea Salt 50 Gallons, For Marine Aquariums, Fast Dissolving --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vu/products/14241074-caribsea-liferock-base-rock-40-lbs-natural-aragonite-rock-custom](https://www.desertcart.vu/products/14241074-caribsea-liferock-base-rock-40-lbs-natural-aragonite-rock-custom) --- *Product available on Desertcart Vanuatu* *Store origin: VU* *Last updated: 2026-05-04*
