We now come to the only difference between scaping a hardscape and creating a planted tank. For a planted tank you usually need to put your substrate into the aquarium first. The only time you must deviate from this course is if you are using large rocks and you want them to be partially embedded into the substrate — or if you need to place your rocks as barrier, to keep different levels of substrate from collapsing forward!

On this video i'll show how to setup the hardscape for a planted aquarium. Adding fertile soil, rocks and wood you'll be able to see how i designed my new aquascape.
Planting video will be out soon, don't miss out on this journey "Into the woods".

Natural habitats tend to be much less diverse, persquare foot, than fish tanks. In nature, only a single type of rockwill be seen, surrounded perhaps by a bit of mud or sand. It is veryimprobable that slate, limestone, lava rock, and granite will all befound in the same place. As far as plants go, it is entirely normal fora single species to dominate the entire area. In other words, the mostrealistic aquarium will use only one type of rock and one type ofplant. This works in the aquarists favour: buying plants and rocks inbulk is usually cheaper.We have all heard of the rule of thirds. While slightly different from the Golden Ratio, which was first discovered and realised by the ancient Greeks and has been used in all art forms for thousands of years, it is a derivative of the Golden Ratio. Not only is it held that this ratio permeates all of organic life, and occurs over and over in nature — but it is a foolproof method we can use to design and arrange elements into , be it knick-knacks on a coffee table, books in a shelf, or rocks and plants in an aquarium.During this planning stage factor in the addition of interesting rocks and driftwood which can give your aquarium a very natural tone. Consistent use of one type of rock or driftwood in the tank yields the most aesthetically pleasing results. Plan with foresight and structure your hardscape to suit an aquarium with a few months of growth.So stand back and ask yourself: Do I want to tilt my rocks? (If you do, you need to stick to this same tilt throughout!) Do I want different levels? Would terraces make my scape more interesting, or more dynamic? Will I have to shore up substrate when I get to that stage? What colour substrate will look best with my arrangement? (After all a black substrate would seem discordant with pale rocks) What do I need to do with the back wall of my aquarium? Paint it? What colour? Which plants will work best? Where will my highest plants go? After all, It would be silly to plant a tall sword plant next to my main focal point if its stone is supposed to simulate a mountain! What will show off my plants best? Do my eyes get led from front to back in a natural way? If not, how will I change my arrangement? Will my foreground hardscape element/s be tall enough once my carpeting plants take off? What else do I need to add to make this arrangement better? Or, do I actually need to take something away to make it better?If something bothers you about your scene, remember, For example, if you want to have a large rock, or a series of rocks, to represent a mountain range, the impact will be the greatest if you have some empty space around the rock/s. This contrast is what draws the eye to the mountain. Similarly, open pathways where the foreground extends back into the mid-ground or background will help create a sense of depth, while simultaneously highlighting the rocks/wood/plants along those pathways. Basically, don’t try to fill every inch of space in your aquascape with something — leave some parts open. Do however ensure that you use your entire aquarium, especially from bottom to top. Halfway scaped aquariums always have a stingy feel about them. Occasionally walk away from what you think is the final design and return with fresh eyes. Go have a drink or watch a game! Be patient during this process. Chop and change now. Believe me, it is infinitely easier and much less frustrating to make changes outside of the tank, rather than inside a water-filled aquarium!PRINCIPLES

1. Plant all groups in odd numbers.
2. Fine leaved plants look best in the mid to back center of a tank, with heavier leaved plants toward the edges.
3. Don't use red in the middle as they have a heavy, dark, feel.
4. Dark leaves (red or dark green) look best toward back edges, with light colored leaves toward the center.
5. Arrange plants and hardscape (rocks and wood) to provide good contrast of light and dark areas.
6. Light colored sand provides good contrast to plants.
7. When rocks are used, use multiple sizes, mixing large and small rocks, as in nature.
8. Rock edges should generally be rounded.
10. Hide your intentions with rocks. Allow plants to obscure them to some extent, maybe completely.
11. Aquascapes with unplanted sand in front is a good alternative to the traditional “Nature Aquarium” style of all foreground covered with foreground plants.
12. An attractive layout alternative is a slope up from near the middle up to the two back corners.
