Review: Perfect Addition to My Triops Habitat - I purchased this to enhance my triops' aquarium, and they've been fantastic! The hand-processed quality and unique oolithic texture make them visually appealing and a great addition to the habitat. The rocks are the perfect size for small tanks, and my Triops enjoy exploring them while it also helps maintain the pH of the water. Highly recommended for aquarium enthusiasts and educators! Review: Amazing value, and it gets delivered! - This rocks are pretty decently sized. I actually got 13, so I think that shows you’ll definitely get the 12. The value is there for the price, aquarium limestone was 3x the price at my local fish store. These work in my fish tank at increasing my kH and pH slightly. It helps stabilize the tank water and I’ve noticed it working. ## Features - OOLITIC LIMESTONE | Oolitic limestone is a carbonate rock formed from the cementation of thousands of ooids.

We were testing the effects of acid rain/pollutants on dissolving rocks. And these rocks were perfect for it! Fairly similar in size so we could measure and weight to keep track of the variable for the project. I can see how they could be used for other purposes too. They were nice and shiny. Very good quality. ## Frequently Bought Together - EISCO 12PK Oolitic Limestone, Sedimentary Rock Specimens - Approx. 1" - Geologist Selected & Hand Processed - Great for Science Classrooms - Class Pack - EISCO Raw White Sandstone, Sedimentary Rock Specimen - Approx. 1" - Geologist Selected & Hand Processed - Great for Science Classrooms (12) - EISCO 12PK Raw Porphyritic Granite, Igneous Rock Specimen - Approx. 1"- Geologist Selected & Hand Processed - Great for Science Classrooms --- ## 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.jp/products/216415060-eisco-12pk-oolitic-limestone-sedimentary-rock-specimens-approx-1-geologist](https://www.desertcart.jp/products/216415060-eisco-12pk-oolitic-limestone-sedimentary-rock-specimens-approx-1-geologist) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-07-14*
