I have a giant ciclid with occasional saddleback issues, no matter how clean and well-balanced we keep his tank. I don't know why they work as well as they do but they make medicating much simpler! Thanks for providing all the information on your site about the product, the medication content and dosing recommendation. The product (as mentioned) lacks for packaging and/or instructions. Keep up the good work and your product info. Mary M. Williams, General Partner J. & M. Technical Consulting *….that is a good article (Aquarium Chemistry)....wondershells are a good product. Anonymous *An excellent and cheap way to do this is to keep Wonder Shells in your tank. I always have 2 medium sized ones in my 26g, one that is almost wasted and one that is almost new fishfever

REGULAR WONDER SHELL (no medication)- Mineral Block;
Useful for important mineralization/electrolytes, calcium carbonate, water hardness control, & more.

Please scroll to the bottom to purchase
Please scroll about 2/3 for information about medicated Wonder Shells

• Contains Calcium Carbonate/CaCO3+ cations (a VERY important element for proper osmotic function in fish as well as Redox Balance!); ALL minor, and trace elements in the exact ratio (with the exception of calcium) as found in the ocean, including magnesium sulfate. A few other elements found include: Chloride, Sodium, Sulfate, Potassium, Bicarbonate, Bromide, Borate, Strontium, Fluoride.

Calcium and magnesium have been proven to help fish (and humans) during stress and to help prevent disease due to acid buildup in the body. These elements (along with Sodium Chloride/salt) are important for the prevention (& even treatment) of Columnaris and Saprolegnia/Fish Fungus) (these positive mineral ions play a part in adhesion of Columnaris by reducing surface potential and repulsive forces)

Providing a regular source calcium and other important mineral electrolytes can aid in prevention and treatment of Livebearers/Molly Disease whose general cause is the lack of these elements.

• Adds necessary minerals/electrolytes (very important whether your source is this product or another method) Wonder Shells may also improve Redox Balance, which the latest research shows may be more important to fish health than parameters such as exact pH! Wonder Shells perform this by adding a constant supply of positive calcium and other positive mineral ions that are depleted during Redox Balancing, despite GH tests which cannot discern the ion charge and may show high GH when I reality, these cations are depleted. (see also this article Aquarium Chemistry; GH, KH, pH, Calcium, & Minerals)
Please note that as to Redox and osmoregulation benefits, these benefits are less noticeable to detect, however controlled tests in the 1990s bear this out.

• Aids in Chlorine removal & helps keep aquarium clear

• Excellent for use with Goldfish, Livebearers, Cichlids, and more (although the benefits are not as dramatic, even Discus and other soft water fish can benefit based on the proven fact of the need for calcium and other minerals for osmoregulation and Redox Balance!)
These mineral blocks can help cure scoliosis in fish such as Guppys or even Bettas when lack of minerals is the cause.

• Each shell oxygenates, aerates and aids in neutralizing harmful acids resulting from normal bio processes; this makes the small Wonder Shell an excellent choice for Betta bowls (especially when combined with Bio Lif Indian Almond Leaf Softener).
Also useful in Amazon River environment aquariums such as Discus and Ram Cichlids for addition of positive mineral ions, an excellent balance to peat, Bio Lif (Indian Almond Leaves), driftwood, etc.
The use of Wonder Shells to balance softeners is similar to the concept as popular products such as Atison’s Spa, except with the added benefit of constant mineral replenishment and with Bio Lif a less refined Almond leaf source providing more of the benefits of these almond leaves.
Concerns raising GH with Discus, Angels, etc, is at times over-rated, as this does not take into consideration the fact that positive mineral ions can be depleted while the GH still might test “high”. For use with softwater fish, often a ½ dose of Wonder Shells solves this problem (a medium Wonder Shell for a 60 gallon tank or simply breaking one in half)

• Aids in the maintenance of a stable ph. For maintaining a higher pH or KH Wonder Shells should be combined with baking soda or better; Sea Chem Buffer . Please note that Wonder Shells do NOT generally raise KH or pH, they more aid in maintenance of these parameters by neutralizing harmful acids that result from organic decomposition.

• Regular Wonder Shells can also aid in prevention and even treat HITH by virtue of the necessary minerals found within these products.

• Extremely useful in planted aquariums at maintaining hardness (and I mean general hardness, not KH as studies in photosynthesis prove) to counter act peak daytime photosynthesis. Wonder Shells are also useful for other minerals required by plants. Please see this article for more: Aquarium Plants; Information and care

• The Wonder Shell Mineral Block dissolves approximately as trace elements are depleted in an aquarium; larger aquariums or those low in trace elements will dissolve Wonder Shells at a higher rate until stable. Calcium (which is the carrier for the other elements) will not exceed safe levels as aquariums will precipitate out excess. GH readings will reflect this however the GH will only show the overall hardness, not the balance of trace elements so higher readings (over 200 ppm) are only reflecting excess calcium. I have used Wonder Shells for just this purpose in 1000s of aquariums I have professionally maintained and never have seen a Wonder Shell add “too much” calcium or other elements. Keep in mind that if your aquarium is low in electrolytes that your fish may temporarily react to the increased trace and minor elements (electrolytes). This would compare to changing water in a tank with high nitrates and too low pH, the fish will need to be adjusted to the improved water quality.

• Can be used in marine aquariums, although better methods of adding essential minerals are available for reef aquariums in particular (such as with many SeaChem products). However Wonder Shells are Excellent for use in RO water storage to aid in re-mineralization of RO water prior to top off for evaporation or mixing. As well for fish only marine tanks they still can be useful in mineral maintenance.

• Provides crabs, snails and turtles with an easily available source of calcium for healthy shell growth.

• NOT a cure all for poor water management, but a useful tool in proper aquarium maintenance. This is an excellent product, but the name is misleading, as Wonder Shells do not perform “wonders”, it is just a useful however not essential product with more than 30 years of aquarist use to back it up.
It is also worthy of note, that Wonder Shells have been available for years in California where word of mouth as made them very popular despite lack of marketing, poor packaging, and a gimmicky name; WHY? because they work and over 30 years of regional use by average hobbyists and professional aquarium maintenance companies does not make them a fad product as some misinformed forums have stated!
QUITE BLUNTLY THIS PRODUCT OR SIMILAR MINERAL CATION REPLENISHERS ARE TOOLS FOR A HEALTHY AQUARIUM THAT MOST FRESHWATER AQUARISTS SHOULD NOT BE WITHOUT (if in doubt, ask some members at Everything Aquatic or see the article: The importance of Calcium/Minerals in ALL Aquariums)

• NOT the same ingredients as Plaster of Paris as some have stated, the Wonder Shell is vastly superior! See this article for more: Plaster of Paris In Aquariums

• PLEASE NOTE; the Wonder Shells have poor packaging as these are a products that have sold very well over the years purely from “word of mouth” due to the effectiveness of this product (so the manufacturer has never improved the packaging), however the packaging does not reflect how best to use these as the packaging states “the large (“giant”) is for ponds while the medium (“super”) is for 10-15 gallon aquariums”; these directions do NOT reflect how best to use them as the medium works well up to 40 gallons and the large is not only for ponds (actually too small for all but the smallest ponds unless multiples are added).

USE; The Wonder Shells will dissolve approximately as needed for minerals/electrolytes and should be replaced when about ¼ original size. For tanks set up for fish that come from bodies of water that tend to be more soft (these fish still need electrolytes for osmoregulation and Redox Balance), we recommend a ½ “dose” (recommended Wonder Shells per tank size).
The Wonder Shells can also be broken for economy and should be placed in areas of low water current (not filters) for best results.

MEDICATED WONDER SHELL- A useful aquarium treatment/disease prevention to have on hand for any aquarist! An aquarium disease treatment with over 20 years of satisfied customers in both our pet store and professional aquarium maintenance route, now available on the internet! NOT A CURE ALL or a replacement for antibiotic treatment for bacterial infections.
For serious Ich infestations, we recommend SeaChem ParaGuard followed by these Medicated Wonder Shells for prevention/follow up treatment

Active ingredients: Malachite Green, Acriflavin, Copper Sulfate, Methylene Blue
(Can also be used for fungus in aquatic turtles)

MEDICATED WONDER SHELLS:
Small; set of 3 (1-3 gal bowl) - $3.49
Med. (10 -40 gal tank) -$3.59,
Lg. (45-60 gal. tank)- $3.99

Medicated Wonder Shells are a unique product that we have tested on our professional aquarium service (with 30 years experience) and excellent results. It helps oxygenate and add important minerals to your aquarium or small pond. But in addition to that it helps prevent and treat Ich (and other protozoan diseases), fungal, some bacterial diseases, even green water.
This product has the advantage of a steady flow of medication unlike the spikes of medication in traditional treatments, which is easier on the fish. An excellent product for use with Gouramis, goldfish, livebearers, discus and more. As a preventative, we recommend adding a shell(s) when you add new fish.
As a treatment, treat 2-3 weeks (and no longer); add another shell when the first one is 2/3 dissolved (a partial water change at this time is recommended). HOWEVER, since this is a Medicated product I do not recommend keeping a Medicated Wonder Shell in an aquarium past 3 weeks and I recommend a 3-4 week period between usages, (unlike the regular Wonder Shells which can be used continuously). We recommend the super wonder shell for 10 to 35 gallon aquariums and the giant for 40 gallon or larger aquariums/ponds. Use one giant wonder shell per 40 -60 gallons of aquarium or pond water.
Carbon filtration may be used during treatment but monitor results especially if being used as a treatment as use with carbon present lowers effectiveness, especially if used as a treatment, as compared to a preventative (even as a preventative carbon lowers effectiveness).

• Probably one of the most effective treatments for velvet available, as the copper sulfate and methylene blue not only kill the swimming stage (as in ich), but kill velvet (Piscinoodinium pillulare) in the dormant stage by destroying the chloroplasts.
• Effective for mild to moderate Ich infestations
• Effective for true fungal infections
• Another positive to this product is the electrolytes in the wonder shell aids in osmoregulation. While the Calcium buffers the malachite green, which is more toxic at lower pH.
• Not recommended as a cure or treatment for true bacterial diseases.
• Generally safe for use with snails and hardy plants (as copper levels are generally below .05 to .10 ppm), however I do not recommend their use with more sensitive invertebrates or long term use with plants.
• There are years of professional aquarium maintenance use behind this product, however with this experience the acknowledgement that although Medicated Wonder Shells are excellent for prevention, follow up, and treatment for mild to moderate Ich and Fungus infection, I recommend either Quick Cure or more so ParaGuard for serious infections and THEN use the Med. WS for follow up (Medicated Wonder Shells are effective for serious Velvet infections though)

We now have a small size for 1-3 gallon bowls (great for Bettas!). Do NOT use in bowls under 1 gallon. These come in a set of three (the same way the regular small wonder shells are sold) for $2.99 per set of three.

NOW AVAILABLE: MARINE WONDER SHELL (LG. ONLY)-$3.99
Can Be Used In Freshwater Where Only Malachite Green Is Desired (not as effective though-especially for fungus)
Active ingredient: Malachite Green, no copper
One shell per 40 -70 gallon aquarium

They are not as strong as the freshwater wonder shell, as the marine shell is lacking a few ingredients that effective on ich, but hard on invertebrates. The marine wonder shells do work though and are safe for most invertebrates (careful with Cephalopods). We recommend that you follow a few other steps for marine Ich;
(1) Dip your fish in a methylene blue dip solution at double strength for 30 seconds to 1 minute (using freshwater at a ph of 8.2 works best)
(2) If at all possible move the fish to a bare hospital tank (often not possible).
(3) You can safely increase the Marine wonder shell if ich is not responding (not FW Wonder Shell!)
