Ok...if anyone is following my troubles with my fish tank. I just came home from work and tested my tank water with my new master test kit.....if anyone wants to know here are the results...
Ammonia...........0.50
Ph.....................7.6
High Range Ph.........7.4
Nitrite...............0 ppm
nitrate..............40 ppm
Now because I am still a newbie to this fish world and also that I have 3 12 inch red bellie pacus in a 40 gal tank. Could someone tell me if these levels are good or bad

Tomorrow after work I will do a water change and test it again. Maybe if I can get a hold on this...I can fix the Baby Hewy and Dewy's broken noses.
Thank you all for all the help...I am slowly buying the right supplies for my 40 gal fish tank and after I get the hang of this, I would love to buy a smaller tank for my bedroom.............Audrey
PS. I'm hoping to become a better fish mother to my Hewy, Dewy, and Lewy and also Sucky.
