One of the most important ingredients to a successful plant aquarium is strong lighting. As a general rule, 2-3 watts per gallon is sufficient for a well-planted aquarium. Often light is measured on a scale of lux. The following table gives the light requirements in terms of lux for plants growing at different water levels:

I have started a 55g heavily planted aquarium, in the past I used once plant food for my 39g and my Panda Cories died within 3 days. My question. Has anyone have this problem? I’d like to give my plants a boost but I’m afraid. By the way, my perimeters were normal when this occurred. Thanks. In addition to natural décor, plants provide vital functions for aquariums as well.

"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.Reciprocally tropical aquarium plants may die iftemperatures dip much below 70 F. Like the fishes you know, plants haveranges of tolerance and optimum growing temperatures. You mustinvestigate what these are in reference works.1) Full spectrum, i.e. the wavelengths that ourEarth receives via our star the sun are best. There are fluorescent andmetal halide fixtures and lamps that will get you these. Ahem, I wouldpoint out that aquarists "kept" plant tanks long beforeartificial lighting; by using (in)direct sunlight.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.Know this; for most localities water, alkalinity and pHare not worth fooling with. The living system which is your aquariumhas a wide range of tricks to accommodate them. If you should haveabnormally high alkalinity ( > 3 mEq) that your animal and plant mixdisfavor, I suggest blending reverse osmosis, otherwise filtered waterwith some of your tap to bring the value down. Alternatively, if yourwater has too little alkalinity, a store bought, or home-formulated mixof buffering agents will raise the alkalinity value to a point ofsustainable pH and buffering range. You want/need sufficient bufferingcapacity to ward off extreme shifts in pH during night and day.What are low light plants and what can they do in your aquarium? They are often referred to as the “” as they are very easy to maintain and they can thrive in .
