I got my ICP test back and my nitrates are very high. When testing at home with my Hanna high nitrate tester is shows 15. Why is the ICP showing so high and could this be deadly to fish?
Edit. I was doing the Hanna test incorrectly and not waiting the 7 minutes. Now it blinks at 75 and shows out of range. Yikes. No wonder my fish died.
