At this time, it is best to test the water for the ammonia and nitrate levels. Don't overlook testing the pH of the water as well. If you are raising live plants, tend to them each week. Trim them back if they are getting too big, and remove any dead or sick leaves. Re-anchor and new sprouts into your gravel. Coldwater Aquarium Set-up and Care As the hobby of having an aquarium becomes more and more popular, it should be noted that the easiest aquarium to care for and set up is a coldwater tank. As the name suggests, coldwater tanks require no heating set up. This cuts costs when setting up your first tank. Try to recreate their natural environment. It is recommended to keep a variety of plants in the aquarium for guppies to seek refuge. There should be about one to two inches of substrate in the bottom of the tank. Colored rock or dead crushed coral make a nice addition to the aquarium, and may help to make the fish feel more at home. Rooted plants, like tubers need to be anchored to the bottom of the tank. It is suggested that the roots be tied to pieces of rock or wood. These species usually grow to be fairly tall and will add length to an aquarium. When planting these, remember to allow plenty of room for growth. The roots will grow outwards and require additional space. They do scratch more easily than glass. When cleaning your aquarium, be careful not to use paper towels, and harsh or abrasive chemicals, as they can scratch the acrylic surface of the aquarium. Always use a cleaner specifically labeled safe for acrylic. Use plastic or rubber scrubbers, rather than metal to clean the sides of an acrylic tank.
