In his work Pneumatica, Philo observed that inverting a vessel over a burning candle and surrounding the vessel's neck with water resulted in some water rising into the neck. Many centuries later Leonardo da Vinci built on Philo's work by observing that a portion of air is consumed during combustion and respiration.
Gather aged compost mixed with a sandy top soil although not good a source of iron, adding a nail or similar to this compost as it ages can add some iron. Next, add water and then rinse and strain to remove large debris until the water runs relatively clear do not over rinse or you remove nutrients.
I then will let it sit in the open for a few days. However, this will not affect mineral nutrients. The sand that is left is what you mix with your plant roots.
Another substrate suggestion is Seachem Onyx Sand. This product is carbonate rich with high amounts of calcium and magnesium and is particularly suited for plants that prefer large amounts of these minerals such as Anubias or in tanks that are supplied by a water source that is very mineral poor.
The use of Wonder Shells and buffers can help as well. Please be careful when vacuuming with many plant substrates as it is easy to suck the lighter grains up into vacuums and many will mistake these often lighter than gravel substrates as waste, this is especially common with inexperienced aquarium keepers.
Sadly, many of these inexperienced aquarium keepers make statements at Yahoo Answers or YouTube that this substrate represents a "dirty" aquarium often confusing others that do not know better. Not all substrates are light but many are. So, extreme care should be exercised with these light substrates.
You may want to try "kinking" the tubing from the vacuum bell to lower the sucking power or simply avoid areas of plant substrates. Other sands for use as a substrate for planted freshwater aquariums: There is a lot of mis-information both pro and con as to the use of these sands for planted aquariums.
To start with, these sands are primarily silica sand with play sand being more dusty.
Some have stated that silica sand is unsafe for use in either freshwater or saltwater. However, nothing is further from the truth as silica sand is The fact is that your aquarium glass is made primarily made from this ingredient and would also be dangerous to your fish if this were true.
Some advocates of using these sands state that they provide nutrients necessary for plant roots.
This is definitely not true and is NOT a reason to use pool sand or play sand. Sand is inert and plants cannot absorb nutrients from the grains! This is why you use sand as a cap over a substrate such as Flourite or EcoComplete that is capable of absorbing and releasing nutrients for plants.
Please reference this article for further information: The advantages of this product are that it is inexpensive, it looks nice since it is primarily rockand it is simple to use with many nutrients already added.
The disadvantage that is the amount of nutrients in this substrate is lower than the use of the aforementioned plant grower substrates. Transplantation is an important consideration in keeping healthy aquarium plants. Plants, in this regard, are similar to fish, and need time to acclimate.
Extreme shock and sterile gravel are going to play havoc during the initial transplant in to the new aquarium. This shock can last a long period of time this varies by plant, water environment, and transplant methodafter this period the plant will eventually start to grow new leaves and begin to grow.
Gasses such as oxygen and CO2 are added and subtracted from the aquarium via surface agitation. Generally speaking it is oxygen that is added and CO2 that is subtracted.
In nature, CO2 is organically added via fish respiration or other biological activity along with decomposition and chemical reactions such as alkaline buffers upon acids in the water.
Often many "hands-on" advanced aquarium keepers will utilize the most advanced pressurized CO2 system as well as complicated fertilizer delivery. While this might be the way to go for certain high end hobbyists, from my experience as well as other experienced pros the expense of time and money these methods require are not always justified if all you desire is a nice but basic planted aquarium.
In fact, as a generalization, just utilizing good lighting, filtration, and basic fertilizers, as well as simple, natural CO2 generation methods e.
Albeit not to the level of advanced methods think Walstad Method or German method! This of course is not to knock advanced methods for those who want optimal plant growth.
This is where a popular aquarium lighting expert who gave a podcast interview at scapefu. What she and others often miss is "bio-available" CO2, and this can be provided along with good optimal lighting for high light plant growth.
This is again not to say that adding CO2, especially via advanced CO2 systems is "bad", far from it, as this is how you are ONLY going to achieve "crazy" plant growth and it often makes even simple growth easier. But just do not let others convince you to not try some high light plants if you are not planning to use injected CO2 So please read on.Plants respond to a number of different cues in their environment with movement.
These movements are called tropisms. Some examples of tropisms include gravitropism (response to gravity), hydrotropism (response to water), thigmotropism (response to touch), and phototropism (response to light).
Information about capillary action, from the USGS Water Science School. USGS Home Plants and trees couldn't thrive without capillary action.
Plants put down roots into the soil which are capable of carrying water from the soil up into the plant. as these pictures show, the colored water is "drawn" upward, against the pull of gravity. Significant Energy E vents in Earth's and Life's History as of Energy Event.

So as you can see, when the water temps start to change from the seasonal temps changing, there will be movement of these bugs. This is why it is quite common to see flashing during these times and for a period of time until the bugs settle back down.
