The second shows the same liquid a few seconds later after the particles have spread out Diffusion is a physical process where molecules of a material move from an area of high concentration where there are many molecules to an area of low concentration where there are fewer molecules. It is possible to see diffusion happening when two liquids are mixed in a transparent container.
The table is very accurate but your measurements may not be! There are two concerns. First, you need to think about the resolution and accuracy of the test kits. This would indicate CO2 ranging from a low value to an optimum value: If KH is the predominate component of alkalinity, all is well.
However, if other buffers are in the water phosphate buffering products, for exampleyou will get a higher "KH" reading and you will think you have more CO2 than you really have. How does one control pH with CO2? For example, we are blessed with soft tap water, both in terms of KH and GH.
We then inject CO2 to lower the pH to 6.
Carbon dioxide (chemical formula CO 2) is a colorless gas with a density about 60% higher than that of dry air. Carbon dioxide consists of a carbon atom covalently double bonded to two oxygen atoms. It occurs naturally in Earth's atmosphere as a trace benjaminpohle.com current concentration is about % ( ppm) by volume, having risen from pre-industrial levels of ppm. The chemistry at work Exploiting the effect of UV light The Titanium AOP System is a physical process that works by exploiting the photo-catalytic effect created when high energy Ultra Violet UV light (at nm) strikes Titanium Dioxide (TiO2) in the presence of water. Diffusion is a physical process where molecules of a material move from an area of high concentration (where there are many molecules) to an area of low concentration (where there are fewer molecules).. Diffusion usually happens in a solution in gas or in a benjaminpohle.com is possible to see diffusion happening when two liquids are mixed in a transparent container.
What is a good KH for a planted aquarium? That depends on the pH you would like and how much CO2 you want to inject. The pH should be set to suit the species of fish you will keep in the tank.
For a community tank, a neutral pH 7. To figure out the proper KH for this community tank, use Figure 2. Go down from there to determine the amount of KH you should have 5 dKH. That's all there is to it!
One teaspoon of baking soda will increase the hardness of 50 liters 13 gallons of water by about 4 dKH. It is best to adjust the hardness slowly, using a test kit to measure the changes as you go along. If your tap water already has a KH higher than you desire, you have two choices. Another choice is to use reverse osmosis RO to lower the KH of your tap water.
One thing to keep in mind: Most fish books give the desired pH as the pH that is found in the natural environment of the fish but farm raised fish will most likely come from water of neutral pH 7.
The fish will adapt just fine to the resultant pH and they will appreciate the stability and lack of extraneous chemicals! What equipment is needed for CO2 injection? As far as we are concerned, none of the systems offered by the aquarium industry are cost effective.
Various bits and pieces are good, but no one system combines high quality, high capacity and low price. If you have access to the right suppliers, you can assemble a much more capable system for less money. Here is what we recommend: Gas Bottle Get a 5 pound to 20 pound CO2 tank from a welding supply shop.
Welders use CO2 to provide an inert atmosphere so they should be easy to find. If not, check for compressed gas dealers. Other sources include fire extinguisher suppliers and beverage dealers.
Careful shopping may uncover a used tank that will be more cost effective. The place where you buy the tank should be able to refill it. Some will refill while you wait, some will trade a full bottle for an empty, some will send it somewhere to get filled.
Naturally, you don't want it disconnected from the aquarium for very long or your pH will shoot up. We have an old 2.
A 10 pound lasts more than twice as long as a 5 pound, and a 20 pound lasts more than twice as long as a 10 pound they have trouble getting all the pounds into the tank, so 0. Regulator The best is a single stage, two-gauge regulator designed for use on welding gas cylinders.
This reduces the pounds per square inch psi tank pressure to psi. These are cheap but there are no gauges so you don't know when the bottle is about empty. Without gauges, you'll just be surprised some day when you check the controller and find your pH is 8.
The high pressure gauge tells you when the bottle is about empty. The bottle pressure will stay at psi as long as there is liquid CO2 in the bottle.CO2 is plant food Earth's current atmospheric CO2 concentration is almost parts per million (ppm).
Adding another ppm of CO2 to the air has been shown by literally thousands of experiments to greatly increase the growth or biomass production of nearly all plants. How can I get my plants to really grow well? Plants, like all living things, need the proper nutrients to thrive.
Unlike animals which can hunt for food, plants depend on the environment to supply them with the basic nutrients needed for survival and growth.
