Review: Great product but not really able to see how good. Give it a try. - Well I have used an alternative calcium block since taking on my Son’s Florida Soft Shell Turtle in my now redundant marine aquarium some 18 months ago. It’s the type of product that you are advised that you need to add but cannot see any difference that it actually makes. If I looked at reviews then this Zoo Med brand had additional additives over and above calcium, which are beneficial to our Flo. Either way we have a great looking Flo , and I can say that now I have some water tests with the help of Tetra all looks to be at the optimum levels. So they are slow dissolving in the correct water flow environment and will continue to use them at the suggested rate.
Review: Important for turtle owners to have. - 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.

## 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!!
