Well I did another nitrate test again and my test results are still high, I would say between 80 and 100 so it hasn't dropped very much from last weeks test. I have been faithful with one cube of food in the morning and one in the evening, although I have given them a few small pieces of fresh shrimp every other day or so. I have a Salifert Calcium test kit that I have had for several months that I have never used. Before I did my water change this morning I figured I would do a test just to see where the tank was at on the calcium level. Either my tank has a really high calcium level or I did something wrong, I am betting on the latter, lol. Here is what I did, and you can tell me what I did wrong, if you can. My kit tells me to use the syringe and put 2ml of warter in the test tube, add one level test spoon of Ca- 1 and don't mix. Then add 8 drops of Ca- 2, then swirl for 10 seconds. Then take the other syringe and fill with 1 ml of CA 3 and add this to your test tube one drop at a time swirling for a second or two between drops until the water turns from pink-red to a clear blue ( I didn't make it past this point) As soon as I started putting the CA 3 into the test tube, my water turned light blue instead of the pink- red color. Anyone have a clue as to what I am doing wrong here?
