Product Description
Ensure the long-term health of your invertebrate colony with CTWPets Crushed Oyster Shells. This 100 percent natural calcium carbonate supplement is an essential addition to any bioactive terrarium, specifically formulated to meet the nutritional requirements of isopods, snails, and millipedes. In a captive environment, isopods often lack sufficient calcium, which is vital for building a durable exoskeleton and facilitating successful molting. Without adequate supplementation, your colony may face soft shell issues, failed molts, and hindered development. These crushed shells act as a bioavailable mineral source, allowing your clean-up crew to graze as needed. Beyond direct nutrition, this supplement also serves as a beneficial pH buffer for your soil. As organic matter decomposes within a vivarium, substrate can become acidic over time; the natural calcium carbonate helps neutralize this environment, fostering a healthier micro-habitat for your invertebrates. Rudra Retails brings you this premium, USA-imported supplement to ensure your terrarium inhabitants receive the highest quality care. With no artificial additives, fillers, or dyes, it provides a clean and effective way to maintain a thriving, bioactive enclosure. Simply sprinkle a small amount into the habitat or place it in a feeding dish to support robust growth and vitality.
FAQ
Q1. What is oyster shell calcium used for?
Ans: Oyster shell calcium is primarily used to provide a bioavailable source of calcium carbonate for invertebrates like isopods, snails, and hermit crabs. It is essential for their structural development, ensuring they can grow strong exoskeletons and complete their molting process safely.
Q2. What supplements do isopods need?
Ans: While isopods thrive on a base diet of decaying wood and leaf litter, they require calcium supplementation to maintain exoskeleton health. Protein sources are also often recommended to support colony growth and reproductive health.
Q3. Is oyster shell calcium good for plants?
Ans: Oyster shell calcium is a slow-release source of calcium that can help raise the pH of acidic soil. While it can be beneficial for some plants, it is primarily marketed as an animal nutritional supplement for vivarium use.
Q4. Are these CTWPets products authentic?
Ans: Yes, all products sold by Rudra Retails, including this CTWPets supplement, are authentic USA-imported goods. We source our inventory directly to ensure our customers receive genuine, high-quality supplies for their pets.
Q5. Can I use reptile calcium for isopods?
Ans: While some reptile calcium supplements may contain vitamins (like D3) that are unnecessary or potentially harmful for isopods, pure calcium carbonate is generally considered safe. However, natural crushed oyster shells are preferred by many keepers as they are free from additives and last longer in the enclosure.
