I tested all of my water Sunday afternoon and realized I was missing a nitrate test, I've been testing my water all along and had some how forgotten about it. I went down to the store and bought a test. I waited until my son went to sleep to test and the tested water turned blood red in the vile. I was doing a 50% water change around 9:30-10:00 last night and my husband got in around 11 and shut off the filter and everything else, we didn't want to splash water on anything. It took me forever because I haven't used a siphoning tube in years and it was such a pain. When I got the water out and clean water in, we turned the filter on and it crapped out on us. I had the regular aqueon filter that came with my aquarium and it refused to work, even full of water and the aquarium full. It just puttered out a few bubbles and wouldn't suck anything into it, even with new media. Today I went out and bought an emporer by marineland. It works a lot better and I like how the water ripples off the wheel and across the surface of the water. I didn't get finished with the fish tank until around 1 a.m. because I didn't have enough water to finish filling it and had to make more. Both of my fish bit my fingers, they were so pissed at me playing in the fish tank. I'm still glad I have fish, lol.
