Got up and tested my bucket of water this morning, and my Nitrate levels have drop a lot. I don't know why this would happen, I have no plants in there the water is still perfectly clear (I can see the sand and large glass beads that I places in there to help seed the substraight). Here is a link to the my spread sheet of daily tests: Linky Linky Background: I got a 55 gal tank for Christmas, but due to the placement of the tree I can't move it into the house until the 26th. So I set up my Rena XP3 filter with a 5 gal buck and began to cycle the filter in there I was using fish food, but switched to a shrimp on the 8th day (that was 6 days ago). The water that I added was due to evaporation/loss during testing (I take a cup of water out and test in the house, way to cold to stay out side.) The water in the 5 gal bucket stays between 88* and 92*. If there is anything that I missed let me know and I will be happy to fill you in. Thanks for all the great help you have been.
