aquascape? pernah dengar? mungkin sebagian orang pernah mendengar, tapi bagi yang belum pernah kalian beruntung! karena sekarang saya akan membahas tentang aquascape!! yippiee! so mari kita bahas..
Aquascape is the craft of arranging aquatic plants, as well as rocks, stones, cavework, or driftwood, in an aesthetically pleasing manner within an aquarium—in effect, gardening under water. Aquascape designs include a number of distinct styles, including the colorful Dutch style and the evocative nature style. Typically, an aquascape houses fish as well as plants, although it is possible to create an aquascape with plants only, or even with rockwork or other hardscape and no plants.
the Techniques :
In addition to design, freshwater aquascaping also requires specific methods to maintain healthy plants underwater. Plants are often trimmed to obtain the desired shape, and they can be positioned by tying them in place inconspicuously with thread. Most serious aquascapers use aquarium-safe fertilizers, commonly in liquid or tablet form, to help the plants fill out more rapidly. Some aquarium substrates containing laterite also provide nutrients.
It is also necessary to support photosynthesis, by providing light and carbon dioxide. A variety of lighting systems may be used to produce the full spectrum of light, usually at 2–4 watts per gallon (0.5–1 watts per litre). Lights are usually controlled by a timer that allows the plants to be acclimated to a set cycle. Depending on the number of plants and fish, the aquascape may also require carbon dioxide supplementation. This can be accomplished with a simple homemade system, using a soda bottle filled with yeast, warm water, and sugar, and connected to an airstone in the aquarium, or with a pressurized CO2 tank that injects a set amount of carbon dioxide into the aquarium water.
Algae (including cyanobacteria, as well as true algae) is considered distracting and unwanted in aquascaping, and is controlled in several ways. One is the use of animals that consume algae, such as some fish (notably cyprinids of the genera Crossocheilus and Gyrinocheilus, and catfish of the genera Ancistrus, Hypostomus, and Otocinclus), shrimp, or snails, to clean the algae that collects on the leaves. A second is using adequate light and CO2 to promote rapid growth of desired plants, while controlling nutrient levels, to ensure that the plants utilize all fertilizer without leaving nutrients to support algae.
Although serious aquascapers often use a considerable amount of equipment to provide lighting, filtration, and CO2 supplementation to the tank, some hobbyists choose instead to maintain plants with a minimum of technology, and some have reported success in producing lush plant growth this way. This approach can include the use of soil in place of aquarium gravel, the elimination of CO2 apparatus and most filtration, and limited lighting. Instead, only a few fish are kept, to limit the quantity of fish waste, and the plants themselves are used to perform the water-cleansing role typically played by aquarium filters, by utilizing what fish waste there is as fertilizer.

hmm segini dulu kali ya mungkin kapan2 kita lanjut lg soalnya gw mau pergi.. ciao have a blast weekend folks !!
