I have a ten gallon tank. It has been set up for about five weeks. Right now I have two barbs two cory cats and some ghost shrimp. I have a couple plants in there growing too. I have some of them test strips and this is what they said: Nitrate 20 ppm Nitrite 4.0 ppm the hardness was like 200 alkalinity was like 200 and the ph was between 8 and 8.4. Now I haven't been doing this very long but I know that is bad. I have tried everything to fix it. What am I doing wrong?????? My fish seem fine but apparently the water is in bad shape. PLEASE HELP!!!!!!!!!!!
