In short, live aquarium plants are essential in the creation of a natural or close to natural environment for most freshwater aquarium fish.
Artificial lighting in aquariums is essential in growing and maintaining healthy plants. Light is needed for photosynthesis, and therefore it should be supplied for about 10 to 14 hours a day. Connecting the lights to timer switches can help in controlling this. Most aquarium plants need plenty of light, however some species can do well with less lighting. As a general rule, plants with light green or red leaves need brighter lights than those with dark green leaves. There are several different types of lighting available for aquariums. Usually, fluorescent lighting is better for smaller aquariums and is cheaper than other types of lighting. Fluorescent lighting for aquariums usually produce a reddish yellow or reddish purple color. They are very efficient and cheap. About 2 watts of lighting should be supplied for every 4 liters of water. Fluorescent tubes should be changed every 6 months to a year because they become less effective over time. Mercury vapor lamps and halogen lamps both provide high intensity lighting and are suitable for larger, deeper aquariums (about 24 inches deep). They are generally placed above the aquarium (about 12 inches). Halogen lamps are more expensive than mercury vapor lamps, but they provide the best lighting for most plants.
undulate, C. wendtii. Crypts can survive unbelievable abuse and are ideal for a brackish aquarium. They tolerate low lighting and withstand a temperature range of 68 to 85 degrees. They are sensitive to transplanting and often experience a temporary condition referred to as “crypt melt” when the leaves seemingly melt away. This is not a sign of the plant succumbing; rather, it is adjusting to new water and light conditions. Sometimes hobbyists erroneously think this condition is the result of salt. Cryptocorynes need a nutrient-rich substrate. Carbon dioxide is not required.

Freshwater Aquariums: Are Live Plants for Your Aquarium?
"My plants won't grow"; "I'm goingback to plastic!" "Hey, where's my burping clam andcolored gravel?" Arrgghhh, Dear Reader, how long is it going totake before the west catches on to "real aquariums",freshwater systems with live aquatic plants? I've waited throughdecades of excuses, house-plant larceny, blaming of undergravelfilters, claims of non-green-thumbness... I can wait no longer. Here,in easy, understandable terms are the principal "reasons" andremedies why aquarists have so little success (please don't call itluck) with aquatic plants. Don't despair, help is on the way.A pH value that is too high can be and is a real problemin many parts of the U.S.. This phenomenon affects the solubility, andusability of nutrients and many life functions. Many aquaristscomplaints with live plants can be cured with an understanding andmanipulation of this variable. Once again, beware; without a concurrentawareness of what buffering is and how it is related to pH, you are"playing with fire" simply trying to manipulate pH alone. Astable range of pH near 6.5 to 7.5 is desiraable, but how you get theremay make all the difference. Do avail yourself of help with analkalinity test kit, other aquarists help and enough "booklearning" till you feel comfortable in altering the pH of yourwater.
