## Questions & Answers

**Q: If my pool has nitrates, what products can I use to remove them? I cannot seem to find anything called nitrate remover on amazon.**
A: There is no product,  you have to drain half of the water out ,, fill it back up and get the chemicals you need back in there .  Only way to get rid if them is drianing your pool unfortunately.. I had to do this recently

**Q: "Why does the nitrate test include nitrites when there is a separate test/pad for nitrites? Thank you.**
A: In the Nitrification process there is oxidation of ammonium to nitrite and then oxidation from nitrite to nitrate. We use these test strips in our microbiology labs to demonstrate these changes that occur. The bottom pad actually contains ingredients that will reduce any nitrates in the water to nitrites and will react to give the pink to red color. So, the bottom pad actually measures both nitrites plus nitrates combined.
