## Questions & Answers

**Q: Does it contain  stabilizer, or is it not stabilized?**
A: I bought this product because calcium is not supposed to have stabilizer, but after five applications, my CYA reading is increasing. I am not happy.

**Q: Is it a loose product and if so dose it come with a measuring cup for the required 1lb add ?**
A: As the picture shows, it comes in a 50 lb bucket.  There is a plastic measuring cup in it, but I didn't find it until i was half way through the bucket.

**Q: how long ship???????**
A: My only problem with shipping is that you have to be present for delivery.  We wound up having to pick it up at our local warehouse for fedex.

**Q: Can I use this for waste water treatment?**
A: I am no chemist, but it does clear up the pool when it turns green.  So I suppose that you could, but I really do not know.  Best of luck.
