## Questions & Answers

**Q: When when are you getting a niterite  alertare you going to get a nitrite alert**
A: I am very sorry to tell you "THE BEST THING TO DO WITH THIS ITEM IS PUT THEM IN THE BIN" !! mine said different readings constantly STICK TO STANDARD TEST KITS ...

**Q: Has anyone had a similar problem as both of my cards havent changed colour since puttimg it in the tank 3 hours ago, followed instructions ?**
A: You should not really expect much change in colour unless you have a really bad water quality, I found hardly any noticeable change. I used for over 6 months and I'm sure it stayed a pale yellowy shade.

**Q: What size is each of these cards?**
A: 2 inch high 1inch wide ruffly

**Q: Will the ph reader work for malawi cichlids with seachem cichlid salt?**
A: Should do, I use it malawi tanks although I don't use seachem chichlid salt any more because of its high price.  Bicarb and epsom salts much cheaper.
