GOGGLES! PRACTICE FIXING AND TITRATING FOR DO LAB Fill sample bottle from bucket - Gently submerge entire bottle - Try to mix water/air as little as possible - Make sure there are no air bubbles in bottle - Screw on cap under water before removing it Follow directions in your test kit to fix water sample Follow directions in your test kit to titrate the sample - Remove a 20 mL sample PRACTICE testing for Phosphate and Nitrate - Fill test kit tubes from stock bottle - Follow directions in your test kit - Use one tube for phosphate test and the other for nitrogen test GOGGLES!
