Seachem Flourite Black Clay Gravel - Stable Porous Natural Planted Aquarium Substrate 15.4 lbs
- GRAVEL: Seachem Flourite Black is a specially fracted stable porous clay gravel for the natural planted aquarium. Its appearance is best suited to planted aquaria, but may be used in any freshwater aquarium environment.
- AQUARIUM BED: Gravel modifiers such as laterite are not necessary when using Seachem Flourite Black as this product is most effective when used alone as an integral substrate bed, but it may be mixed with other gravels.
- SET-UP: When adding water to the aquarium, fill slowly to avoid disturbing Flourite Black substrate bed. Place a bowl in the aquarium and add water directly to the bowl, allowing water to overflow softly on to the gravel bed. Initial cloudiness is normal, but to remove this simply use mechanical filtration
- COMPATIBLE: Flourite Black substrates will work fine with an under gravel filter and will not soften or decompose to an unsuitable state within your tank.
- SAFETY: Seachem Flourite Black is not chemically coated or treated, thus does not alter the pH of the water. Flourite Black is beneficial for the life of the aquarium and need not be replaced.

ADA Aqua Soil Amazonia (3 Liter) Normal Type
- Completely new substrate made from rare and sparse source of Japanese plant-based black soil derived from decomposed leaf mulch. (unlike imitation products that are made from volcanic ash-based black soil).
- Rich in organic elements and nutrients that creates conditions ideal for healthy growth of aquatic plants and has a good influence on the physiological functions of fish and shrimp.
- Helps to bring the pH level and hardness of the water down to an ideal level for most of the aquatic plants.
- Composed of granules of size and density ideal for the fast development of healthy plant root systems. Granules have a natural irregular shape that produces a natural look.
- Contains high levels of natural humic acid that may or may not cause some initial water cloudiness depending on your local water chemistry. Water cloudiness will go away with proper maintenance and water changes. Therefore, this product is recommended for advanced hobbyist seeking to make a fully planted aquarium. For beginners, we recommend the easier to handle Aqua soil Amazonia Light.
U.P. Aqua Shrimp Sand
- Small uniform grain sizes
- Contains trace minerals vital for shrimps
- Easy to maintain, great for breeding

How Various Environmental Conditions Change the Catalytic Capacity of Biological Enzymes
This article describes how temperature and substrate concentration changes the reaction velocity of chemical reactions catalyzed by enzymes.
Enzymes can also be set to function by lowering the activation energy of the chemical reaction since enzymes accelerate reactions by decreasing ?G, which is the free energy of activation. The rate of the reaction is generally proportional to the concentration of the substrate, when all other things are kept constant.
The catalytic power of enzymes comes from the fact that they bring substrates together in a favorable orientation, which helps to promote the formation of the transition states in enzyme - substrate (ES) complexes.
Generally with internal catalyzed reactions, as substrate concentration increases, the rate of the reaction increases since more substrate molecules collide with enzyme molecules and hence more reactions take place.
At higher concentrations of substrate, the enzyme molecules become saturated so that there are only a few free enzyme molecules. Technically what type ends when the amount of enzyme is kept constant and the concentration of the substrate is increased, the reaction velocity will increase up to a maximum point. After this point any increase in substrate concentration will no longer increase the reaction velocity or rate.
Most enzymes generally have an optimum temperature at which they work best. For most mammalian enzymes, this temperature is around 40° C though most enzymes generally work at different temperatures depending on where they are found and their specific role. The rates of enzyme catalyzed reactions generally increases gradually up to their optimum temperature, the rate increase is due to the fact that the enzyme and some should molecules gain kinetic energy due to the increasing temperature so random collisions occur more often (random collisions are the cause of all chemical reactions).
Above the optimum temperature the rate of the reaction decreases due to the fact that the enzyme molecules become denatured. This denaturation disrupts the three-dimensional structure of the enzyme protein and causes it to loose function. The thermal energy from the increasing temperature causes the bonds holding the secondary and tertiary structures of the protein to be broken. The active site of the enzyme also loses its shape and that such substrates can no longer bind to the active site, and hence reaction velocity decreases.
