Great product which slowly lets loose over time. Was lovely to see it break down and the turtle was happy with it in there. The little stream of air bubbles when placed in were a great experience too. Review: Good product - I am new to owning turtles so I wasn't too sure what I needed to aid with their health. I came across these and although it's difficult to know whether they actually work my turtles seem to be happy and healthy which is great. ## Features - A slow release calcium block that conditions water - Providing a calcium supplement to promote healthy shell growth for aquatic turtles - For using it, simply place in your turtles water supply - Model number: VZD200 ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0061TC8C2 | | Best Sellers Rank | 5,693 in Pet Supplies ( See Top 100 in Pet Supplies ) 69 in Aquarium Water Treatments | | Brand | Zoo Med | | Brand Name | Zoo Med | | Country Of Origin | USA | | Customer Reviews | 4.4 out of 5 stars 1,615 Reviews | | Item Form | block | | Item Weight | 0.02 Pounds | | Item form | block | | Item weight | 0.02 Pounds | | Manufacturer | Zoo Med | | Manufacturer Part Number | ZML-051 | | Model Number | 26223 | | Number of Items | 1 | | Target Species | Turtle | | UPC | 097612800128 | | Unit Count | 1 count | | Unit count | 1 count | ## Product Details - **Brand:** Zoo Med - **Item form:** block - **Item weight:** 9 g - **Liquid volume:** 15 Gallons - **Unit count:** 1 count ## Images ![Zoo Med MD-11E Dr Turtle Calcium Block - Image 1](https://m.media-amazon.com/images/I/91tkgVDtD6L.jpg) ![Zoo Med MD-11E Dr Turtle Calcium Block - Image 2](https://m.media-amazon.com/images/I/71u+tjg9WYL.jpg) ![Zoo Med MD-11E Dr Turtle Calcium Block - Image 3](https://m.media-amazon.com/images/I/712nmT7a+ZL.jpg) ![Zoo Med MD-11E Dr Turtle Calcium Block - Image 4](https://m.media-amazon.com/images/I/41XDn7hbQlL.jpg) ![Zoo Med MD-11E Dr Turtle Calcium Block - Image 5](https://m.media-amazon.com/images/I/313ZWHz2xJL.jpg) ## Questions & Answers **Q: Is it suitable if fish also live in the tank?** A: Yea it's just slow release calcium **Q: Does it make the water cloudy/dirty at all?** A: Do not buy this. It is so bad for your turtle. Buy Cuttle Bone instead it leaves no cloud and is 100% healthy. Please don't buy this it's so toxic Nd can make your turtle seriously ill **Q: Do this go into the filter or tank?** A: Tank **Q: Is this suitable for tortoises ?** A: This isn't meant for tortoises and is meant for slow release in water for aquatic turtles/terrapins. My terrapin bit it to pieces quickly and probably consumed some too without harm. I would think a tortoise, especially a large one, would quickly destroy it too, and perhaps consume too much in one go. Zoo Med do a larger tortoise block which I have found excellent for my tortoises. It is bigger, more substantial, and therefore takes the tortoise much longer to consume the calcium and wear down its beak in the process. My Horsfield tortoise actually mounts the block so you could say its environment enrichment at the same time!! ## Customer Reviews ### ⭐⭐⭐⭐⭐ It breaks down slowly *by M***E on 15 May 2025* A little calcium turtle to put in a turtle tank to help our turtles shell. Great product which slowly lets loose over time. Was lovely to see it break down and the turtle was happy with it in there. The little stream of air bubbles when placed in were a great experience too. ### ⭐⭐⭐⭐⭐ Good product *by S***D on 24 April 2025* I am new to owning turtles so I wasn't too sure what I needed to aid with their health. I came across these and although it's difficult to know whether they actually work my turtles seem to be happy and healthy which is great. ### ⭐⭐⭐⭐⭐ Important for turtle owners to have. *by D***O on 29 May 2025* Very good for the swimming water of my 2 little turtles i like seeing the bubbles it creates the most makes the water look fresh and makes some really nice pictures and videos out of it. Longevity of the calcuim block i believe lasts around 7 - 12 days size is perfect and the block itself prevents the aqautic tank smelling like a wet dog. Value for monies indeed and is exceptionally healthy for the turtles just don't think my filtration system agrees with it so i will have to clean inside my filtration system more regularly than before. As long as the turtles are happy then i am going to continue on buying these calcium blocks. ## Frequently Bought Together - Zoo Med MD-11E Dr Turtle Calcium Block - King British Turtle and Terrapin Multivitamin 20ml - King British – Turtle & Terrapin Water Freshener 100ml – For Cleaner & Clearer Water – Removes Harmful Ammonia & Nitrite – Ideal for Setting up a New Aquarium or Partial Water Changes --- ## 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.kr/products/48263752-zoo-med-md-11e-dr-turtle-calcium-block](https://www.desertcart.kr/products/48263752-zoo-med-md-11e-dr-turtle-calcium-block) --- *Product available on Desertcart South Korea* *Store origin: KR* *Last updated: 2026-06-23*
