I did rinse it very well. Then rinsed it again and again and again. The I used vinegar and salt to disinfect it. Then rinsed again and again and again. I bet my water bill is going to take a hit. LOL I was very careful because I know soap will kill fish but I didn't know how else to get all the scum off of it. It was really bad.
I am going to buy another filter like the one I currently have and put one on each side of the tank. It is rated for up to 15 gallons so two should be fine in the 30 gallon shouldn't it? I also have to buy another heater. The one I currently have is only for a 10 gallon tank and I need more gravel. I will be using some of the tumbled rock that was in the 30 gallon but the gravel was disgusting. I am going to put it in the flower pots for drainage. I think I will pick up some live plants the next time I am at Petsmart. I also have to get a hood. The cat doesn't bother the ten gallon but I am not taking any chances. I have plexiglass and I am pretty good at building things so I think I will design my own hood instead of buying one.
What about fish that I listed? How many of each could I get without over crowding? Should I leave any of them off?
