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: Happy Customer - Great Product

## Questions & Answers

**Q: I have 3 RES turtles, they keep eating this thing in few days. Is that okay?**
A: Yes, it is OK.  My turtles (red ears, maps, and cooters) do that too.  Many years ago, I had 2 map turtles, both of which lived for 26 years, that ate calcium blocks when offered.  The turtles I have now totally consume these blocks in 3 days, and the turtles are growing very fast and have very hard shells.  Apparently, it is instinctive for turtles to consume rich calcium sources  such as this.

**Q: Can I use in fish tank to raise ph?**
A: I do mine

**Q: Can this be used in place of a water conditioning liquid? Does it make water safe for fish as well or do I need a separate water conditioner for fish?**
A: No, It does not take the place of water conditioning liquid. It does not remove chlorine or chloramines. These blocks simply adjust pH and water hardness.

**Q: You you have to have a certain amount of water in the tank to use the Dr. Turtle block?**
A: No but if you're doing a bare bottom tank the block will leave a calcium spot on the glass that I never could seem to completely get off
