Answer #1

Well first of all you need to get a water cleanser. They sell it at any pet store or even target and wal mart. You add a few drops and it makes the water softer and cleaner for the fish.

When cleaning a tank NEVER use soap, use a hard scrubber and hot water, soap residue will kill your fish. You can also get something called magnetic aquarium cleaners. One magnet is inside the tank with a scrubbie on it and the other is outside the glass, it will trail the outside magnet when you move it and clean the inside, they work really well.

Answer #2
