## Questions & Answers

**Q: whats the difference between this and their GroLine storage solution?**
A: I use Skunk Labs Potassium Chloride solution . it's cheaper

**Q: After a few days, the solution becomes crystallized and chunky. What am I doing wrong?**
A: Not sure. Mine lasted for weeks and only became crystallized of left uncapped or in the open air . Cld be bad to begin with if only a cpl days . Try gettin a refund or a new order and see what happens ..

**Q: How much of this are we supposed to use on the ORP meter tip?  Just pour some into the basin that the tip slides into?**
A: Well Hanna says not to store the unit in that cap for what reason idk at least on my ph 55 meter  but I use those packets it comes with to store it in and use just enuff to cover the electrode then change it once a week or so  not sure what ph meter u have but you could most likely use the cap I used it on the last unit I owned so ur call

**Q: This is probably an obvious answer but I thought I'd be careful; Can this storage solution be used for an Oakton pH meter?  This is way cheaper.**
A: I'm sure its universal just one thing when I used it, it got crusty on me so I just use ph 4 or 7 solution to store mine in and use the cleanin solution once a week on it is all but it would work for your meter if you wanna try it out for yourself and see.
