| Directions | Use dosing cap on bottle. Shake well. Add 5 ml per 10 gallons (38 L) of aquarium water. Tips: In natural reefs, calcium levels are very stable and changes are gradual, so when adding calcium to an aquarium, it is advisable to raise calcium to the desired level over several days and not all at once.

your snails will love calcium
my snails looks so much better after using this! i looked far and wide for a good calcium supplement to help out some of my snail tanks and their shells looks great. The bottle is large so it's going to last a very long time because you only need the tiniest bit each time. super easy to use and a very sturdy bottle i can bring around with me

Freshwater snails love it
I bought this for my nerite and mystery snails, as their shells looked a bit damaged when I bought them. I tried cuttlebones, Tums, and crushed eggshells, also Wonder Shells, and nothing was working very well. After buying this product, I dose 5ml in 20gals weekly after 75% water changes. Freshwater aquarium. The snails are growing quickly, the mystery snail is now HUGE! The shrimp also appreciate it as well, I have been seeing more intact molts. Just keep in mind that minerals like calcium do not evaporate, so unless you are changing 100% of the water each time you add calcium (not recommended!), the concentration will increase. I check the kH and gH levels weekly as well to monitor this.

If u use this before aquarium is bad, just when water starts to turn it works great.

Great for Mystery Snail tank..
My snail's shells were starting to look a little off no matter what I did with the water to add calcium. My PH and everything was great so decided to try this. Their new growth looks amazing. This is now a staple for my mystery snail tank.

Snails love it
My snails seem to love it. After a water change and adding this I have an "explosion" of baby snails. Snails are my 'to to' workers to keep my tank as algae free as possible. I have a lot of sunlight on my tank and snails help keep it looking awesome.
