Aquascaping your aquarium gives makes fish happy and healthy. Many tropical fish are native to a world that includes aquatic plants. Live aquarium plants serve as food for aquatic life and also provide fish and fish fry places for retreat. Your fish will behave more naturally, display better finnage and courtship behaviors, and have more intense coloring.
Over 70% of the aquarium should be planted with various species of aquatic plants.

Another way to utilize NilocG Enhance Seachem Flourish Excel for bioavailable carbon (CO2) in a better, staggered way, rather than all at once, is a calibrated drip system.
In this experiment I was able to get 20 drops per minute. I measured 20 drops and this was equal to a ¼ tsp. So 4 minutes would equal 1 tsp. There are 6 tsp in one fluid ounce. So at this rate you will go through a ounce in 24 minutes. Add the correct dosage for your aquarium size then add the water (RO or DI water is best to mix with Flourish).

Example: For a 50 gallon planted aquarium you would add one capful (5 mL) of Flourish Excel (or 5 mL of NilocG Enhance). Then, depending upon how long you would like to stagger the drip would determine the amount of water. For this example I would suggest 20 oz. of water to mix for 8 hours of drip (24 minutes per ounce x 20 ounces water/Flourish Excel solution).
With larger containers, longer dosing times can be achieved.
However, even though Flourish Excel or Enhance can remain active for 24 hours, from my experience I would suggest 8 hours for best results (keeping in mind that CO2 is not utilized by plants after dark as they use oxygen instead during non-photosynthetic periods).

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.With so many different types of species of floating aquatic plants, you can definitely find the one that fits your aquarium the best. However you might be wondering why would you have floating plants in your tank? Well, today I’m going to share some of the benefits of having such plants in your aquarium.Floating aquarium plants are an amazing feature to have in any tank. Floating plants are not attached to the bottom of the tank and they come in a lot of different shapes and sizes from very small to over a foot in diameter. Some of them have roots that hang in the water from the plants floating above them.The aeration in a planted aquarium is usually regulated by live plants just as it would have been in the wild. Some of the floating aquarium plants regulate oxygen so that the fish can breathe.Providing the perfect shading for your other water plants and cover for your fish from the tank lights during the day is an important part of every aquarium. Creating a shade for the fish will really bring out their potential and their different colors. Just remember, if you choose to cover the whole surface of your tank it will possibly reduce the growth of your other plants, so it’s wise not to overdo it.Floating aquarium plants can be helpful as filters to remove all fish waste in the aquarium. The bacterium growing on the plant is used as a filter media and it can deal with biological and/or chemical filtration unbelievably well. Absorbing the chemicals that can be harmful to the fish can be a very daunting time for the floating aquarium plants so it’s always wise, but not mandatory, to have a at hand. These floating plants will be a great protection for your fish helping them to avoid diseases and finding a great place for fish to hide or play.
