Substrate fertilizers/trace element products come in two varieties of applications. Pre-mix and “as needed”. The pre-mix versions are designed to be mixed with the gravel before the aquarium is set up and placed on the bottom of the tank. Then you cover this mix with another 2-3 inches of standard substrate. This type obviously does not lend itself well to addition after the initial set up.

While there is no absolute answer to this question, substrates that are porous and have an average size of 2-3 mm. will work best. If the substrate is too fine, there is a risk that it will pack down too tightly and create dead areas. If the substrate is too coarse, small areas will develop that trap waste and create pockets of decay. While smooth surface substrate will not allow proper root attachment, a porous surface allows good root attachment and helps to anchor the plant in place. See similar questions...

I add about a pound of garden food per one hundred square feet in the fall and then feed my garden with a liquid garden food right after I plant in the spring. See similar questions...

Aquariums should be moved without water in them. We also recommend removing gravel and decorations. Damages caused from moving an aquarium are not covered under the warranty. See similar questions...

attractive substrate makes the tank look nice, can trap some dirt or hide it, and provides anchor for roots of plants. Some cichlids use the gravel (spawning pits, etc.) and gravel can help to buffer the water and, in some cases, provide a substrate for nitrate cycle bacteria. The size of gravel you choose will depend on the type of cichlids you are keeping, whether you want to have a planted tank, and whether you want to breed your fish. See similar questions...

Fluorilon-99 is a monolithic thermoplastic. It is not a coating and thus cannot be applied like one. However, thin sheets of Fluorilon-99 can be prepared and adhered to substrates with certain adhesives. While this procedures is not recommended, in certain cases it can be successfully employed.

Well in some ways it can be in any non-toxic container that can hold water, but some things just work better than others. I prefer glass tanks. But I'm old fashioned. Most of my tanks are the plain old rectangular glass fish tanks. There are a lot of fancy new tanks with bowed fronts and different shapes. Most tanks are pretty well suited to do the job. Extra tall tanks should usually be avoided but they can be used sometimes if the extra height is taken into consideration. See similar questions...

A) No! Research has shown that plain tap water is by far the best. Some commercial additives and home concoctions can actually be detrimental to a tree's moisture retention and increase needle loss. Water-holding stands that are kept filled with plain water will extend the freshness of trees for weeks. See similar questions...

No. It's always better to underwater than to overwater; you can always add water, but once it's in the pot, you can't take it out very easily. Any plant that gets too much water and fertilizer will suffer and begin to die. Some plants like an acid fertilizer, others require an alkaline-based fertilizer. It's important to be sure which type your specific plants need before you go dosing them with whatever fertilizer you have sitting around the house. See similar questions...

Paternity can be established in the following ways. The first is through the voluntary acknowledgment process where a form known as an "Acknowledgment of Paternity Affidavit" is completed. It can be filled out at the hospital when your child is born, before both parents leave the hospital. It can also be completed at the CSEA or your local Vital Statistics Registar (usually associated with your local health department). See similar questions...

The concentrations of carbon dioxide and oxygen are independent of one another. Adding carbon dioxide will not drive out oxygen, though the addition of carbon dioxide above 30 PPM can have adverse effects on the fish. Normal concentrations for optimal plant growth are between 10 to 20 PPM. With normal water movement, the oxygen content will be about 8 PPM, though during the daytime, release of oxygen by the plants can lead to a higher oxygen concentration. See similar questions...

Check for external contamination of the lamp by items like: spray, powder, reflector material or other particles. Make sure that coating and ink material is fully mixed before application. This allows the photo initiator to be evenly distributed in the coating media. Verify the number of operating hours that the lamp has run. Different applications result in different lamp lifetimes.

The tungsten carbide cloth is infiltrated by a brazing alloy, which fuses the carbide particles together and wets the substrate, creating a metallurgical bond. See similar questions...

We mainly use paper towels and shelf liner. But newspaper and very fine grade (dust free) sand is fine. Try to avoid wood chips, gravels, lizard litter, and calcium sands. See similar questions...

No. Cut vinyl lettering and graphics can be applied directly to any clean, smooth surface such as a window, vehicle or even an existing sign. We can install your vinyl or supply cut vinyl decals for you to install. We also can make paint stencils - either from reusable plastic or single use paint masks when sharper images are required.

A complete fertilizer simply means it contains the major (macro) nutrients nitrogen, phosphorus, and potassium. Prominently displayed on the front of any complete fertilizer package are three numbers. These numbers refer to the percentage of nitrogen, phosphorus, and potassium respectively. The most common ratio sold for roses is a 1-2-1 ratio, for example 5-10-5. See similar questions...

This is a tough one to answer, because fertilization is so tremendously tied to water quality, potting medium, temperature, light and a variety of other factors. However, if you just have a few plants, and don't want to fuss around a lot learning about the intricacies of water and fertilizer, I'd simply suggest you get any reasonably balanced 'orchid' fertilizer, that is low in urea, and use it at approximately 1/4 to1/2 the label strength every other watering.
