How to Add Calcium to Aquarium for Snails

I’ll be discussing how to add calcium to aquarium for snails. There are many ways to do this, but the most commonly used include adding crushed coral or shells to your filter, feeding your snail calcium powder regularly, and using liquid calcium additives. You must use caution when giving out any supplement as it can disrupt natural systems in your tank. You should also consult with an expert before deciding which option is best for you and your aquatic pets!

Why Add Calcium to Aquarium for Snails

Your aquarium water should have a calcium level of at least 400 ppm, with magnesium levels following close behind at around 1200-1300 ppm. This will ensure that your snails are given the best chance to grow healthy shells and skeletons. If you’re having trouble maintaining these levels, it’s time to start thinking about adding in some calcium supplements.

How to Test for Calcium in Aquarium

Trying to figure out how much calcium is in your tank water can be difficult. You can buy a kit that will test the water for you, but the results may not be 100% accurate. If you want to take a more natural approach, your best bet is to look at how well your snails are growing and doing in their environment.

Test Calcium in Aquarium

If they have enough calcium, their shells should show signs of growth. You might see small “ridges” on the shell or sections that look thicker than others. If there is not enough calcium in your tank water, you’ll notice a thinning of their shells and markings that appear to be faded.

Materials You Need

  • A clean container for mixing/measuring water
  • A calcium supplement of your choice. For a beginner, I would recommend crushed coral or shells since they’re available at pet stores and are easy to work with. It’s also much less expensive than liquid calcium additives.
  • A way to crush the shells up (a pestle and mortar works perfectly.)
  • A way to add the calcium supplement to your tank water. Some people recommend using a syringe, but I prefer the simple cup method.
  • One or more snails!

Methods on How To Add Calcium to Aquarium for Snails

Method 1: Crushed Coral and Shells

Adding crushed coral or shells to your filter is one of the cheaper, easier ways to get extra calcium for your snails. Just place them in your filter where water will flow over them. This method can take a while since the coral/shells must be ground up in order to release enough calcium into the water. Plan on this method taking around 1-2 weeks before you notice a difference in your tank conditions.

Method 2: Calcium Powder

This is one of the more popular ways to add calcium for snails and is done by mixing it with food and feeding directly to your pets. There are many different brands and types of calcium supplements, and you can choose which one is best for you. Before adding it to your tank, consult with the instructions on how much to use and how often.

Method 3: Liquid Calcium

Liquid calcium supplements are a popular option as well. You’ll want to make sure that the liquid supplement is designed specifically for aquariums, as there are other types that will change the ph of your water. Some liquids can be added directly to the tank, while others need to be mixed with food before feeding your snail.

If you’re looking for a more natural source of calcium, try using eggshells! Just crush them up and add them into the tank. You might want to grind the shells down before feeding them to your snails, so they don’t get caught in the filter, but this isn’t necessary. You can also mix crushed shells into their food or provide them with a cuttlebone to chew on throughout the day!

Method 4: Using Flourish Calcium

Flourish calcium is a popular option because it’s safe for snails, corals, and shrimp. Instead of adding it directly to your tank, you add the drops to your water changes along with any other additives. You can choose between either liquid or powder forms, depending on your tank size.

When adding supplements to your tank, always think about what other fish and animals you have in there. If it is necessary to raise the calcium level in your water, do so slowly and monitor how it affects all of your pets. Some fish are better at handling higher calcium levels, while others are sensitive to changes in conditions. If you have any questions about your tank’s water conditions or need help figuring out how much calcium is in there, be sure to contact an expert!

Safety Concerns

When adding calcium supplements to your tank, there are some safety concerns that you should be aware of. If the pH level in your water changes too much, it can be harmful to many aquatic creatures. Additionally, if you have molting snails, they need less calcium than usual, so supplementing during this time can be harmful.

Check Your Ph Level

If you’re thinking about adding calcium to your tank, make sure you understand what it is and how it might affect other animals in the tank. It’s also good to get tips from other members on forums like this before making changes. Then, if anything goes wrong, don’t blame yourself!


If you’re looking for a way to add calcium into your aquarium but don’t want to use any chemical supplements or saltwater, there are a few natural options! Try crushed eggshells, cuttlebone, dried seaweed, and even shrimp shells to get extra calcium. Be sure only to offer small pieces of these items.

Frequently Asked Questions

Where Do You Get Calcium for Snails?

There are many places where you can get calcium for snails.

The most common source of calcium is shellfish, which can be found in the ocean or purchased from a local seafood market. You can also purchase it from your local pet shops.

Calcium is usually added to their food as a supplement, so it may not always be included in the foods that they eat naturally. It is also possible to find some foods that have high levels of calcium like milk and yogurt.

How Do You Make Calcium Blocks for Snails?

Snails need calcium blocks to living and breed.

There are many ways to make calcium blocks for snails. One way is to use old eggshells as the source of calcium, which will be given a nutritional boost by adding fresh vegetables such as lettuce or spinach that have been soaked in a solution of vinegar and water. Vinegar also acts as an antibiotic and helps fight against bacteria.

Another way is to make your homemade calcium block from scratch with flour, cornmeal, baking soda or powder, and water. This method can be done in a bowl by stirring together all the ingredients before adding more water if needed until you get a thick paste-like consistency. You can then spread this mixture onto pieces of cardboard or parchment paper until it’s about ¼ inch thick.

What Can I Feed My Mystery Snail for Calcium?

Mystery snails are carnivorous, and as such, they need a diet that is high in calcium. One of the best foods for them to eat is crushed eggshells. You can feed them this or give them regular food, but it is important to note that the calcium content of their food should be at least 25% of their body weight.

For example, if your mystery snail weighs 1 gram, then you would need to provide it with about 0.25 grams of crushed eggshells for every day’s worth of food (2 days).

How Do You Prepare Cuttlebone for Snails?

Cuttlebone is a type of food that snails need to survive. There are many ways in which cuttlebone can be prepared for snails, but the most common way is to put it in an aquarium with tap water and place a snail on top of it.

Put Snails in an Aquarium


The best thing you can do for your snails is to add calcium. To get the most out of this supplement, you must have a varied diet and fresh-water supply in their habitat. You should also avoid using salt or any other supplements, as these will only worsen the problem and make them sicker than ever before.

Instead, ensure they get enough food each day by feeding them algae wafers, lettuce leaves, cucumber slices, spinach flakes, and dry dog food pellets, all of which contain high calcium levels!
