Thanks. The tank is only about a week old, I transfered all of the fish from my 25 gallon to the 50. It isnt very stocked till it cycles, I have 2 Bala sharks, 2 frogs, 2 shrimp, 4 glass cats, 3 cat fish, 3 swordtails, 2 gold dust platty's , 1 puffer, 2 kirbensis, and 2 danios. Half the water in the tank is from my 25 gallon, which was set up for a few months, so it has good bacteria or whatever in it. I am also running an Aqua Clear 70, with the amonia bag, charcoal bag and foam. I did a test on saturday and the PH, Nitrates-a little high as its a new tank, but not too bad. And everything else my tester kit does is within range. I know that may seem like alot of fish for the tank but they are all still on a few months old, the oldest I think is almost 4 months. So they aren't very big yet. But that is the reason I upgraded to the 50 is cause the 25 wouldn't be big enough for them.
