What do diatoms and soluble silicates mean to you and your tank?
If your water has "low" soluble silicates (<1-2ppm for FW, in my personal usage), a freshly set new tank with all new water may well develop an unsightly brown film on the glass, ...

Diatomaceous Earth Filters
Diatomaceous Earth is a granular media, made up of the skeletal remains of diatoms (bacillariophyta). They are sometimes used as an alternative to cartridge filters, where very fine filtration is required.

Diatom Filter: This purely mechanical filter uses diatomaceous earth to remove very fine particles from the water. They clog quickly and are only used occasionally as water polishers rather than continuously. See diatomaceous earth.

Diatom Filter - A mechanical filter that uses diatomaceous earth to remove fine particles
from the water.

Discus - A cichlid from South America. The King of freshwater fish! ...

Diatom Filter: Filters which use a diatomic filter media. Diatoms are small single celled protists which have silica shells.
Dorsal Surface: The top part of the fish.

Diatomic filter:
These filters are also another type of filter not usually seen. The unit consist of a prescreened intake and a chamber for holding media. These can be hob or look much like a canister filter.

Diatoms: An organism that commonly forms brown films on aquarium glass or rocks. Diatoms form their shells from silicate, and can be controlled to some degree by preventing the addition of this compound through the use of purified water.

Diatom Filter - A Filter which employs the use of diatom powder (the skeletal remains of diatoms). Used to 'polish' the water by filtering out particles as small as 1 micron.

diatoms
A primitive single-celled algae; also a common phytoplankton.

Diatoms (Bacillariophyta) - floating brown algae that is among the first algae to appear in a tank. These develop silica shells and are abundant in plankton. Ensure proper filtration, as they live on organic wastes.

Diatomaceous earth filters, commonly available in canister filters, can remove particles as small as 3 microns in size which really 'polishes' the water.

Brown diatom algae - common in new tank set ups but it can appear in established tanks if the conditions are right. It should disappear as the tank settles but can last for a few weeks or so.

Diatoms compete with blue-green algae for resources (#1 reason to mention this here).
Diatoms are much easier to remove from glass and acrylic and less unsightly than blue-green algae (light gold tint compared to algae's green blotches).

Diatomic or micron filtration
Introduce daphnia to the tank
Water changes will reduce green water temporarily, but will not eliminate it. Completely blocking out all light for three days or more is very effective.

Diatom skeletons are composed of silica and there has been some speculation as to whether usage in marine aquaria will lead to "brown algae" explosions. EXTERNAL FILTERS Oftentimes, this is used to denote power filters. But this not always the case.

Diatoms Single celled protists with silica shells.

Diatoms - A single celled organism that forms a brown film on the aquarium glass, substrate and rocks.

Diatom Filters use a powder to charge the filter, the powder, diatomaceous earth consist of the skeletons of millions upon millions of two celled animals.

For diatom or algae control, you can use the algae blenny, Salarias fasciatus.
This looks a lot more cute than the freshwater plecs, and doesn't grow as large.
Some of them will even take pellet and other food, when it runs out of diatoms.

Use diatom powder in a DE or canister filter to remove water-borne parasites from a tank, or to speed up wound healing.

Sounds like diatoms due to excess silicates in the water You can wipe them off by going from the bottom to the top of a pane with a sponge, then rinsing the sponge, then wiping another area and rinsing again and so on.

Also, brown algae (diatoms) are very common with new aquariums going though the nitrogen cycling process. Eventually these brown spots will be starved out of the aquarium if you do proper maintenance.
Causes of Algae Growth ...

An algae bloom can be removed by filtering with micron cartridges or diatom filters. UV sterilizers can prevent the bloom in the first place. Green water is very useful in the raising of daphnia and brine shrimp.
Film algae ...

Diatoms take up silica in the construction of their shells, and release it back into the water, as they dissolve in the water column, and some of the diatoms get buried and preserved within the substrate.

plus a marine tank will go through many different cycles, they usually come as ammonia-nitrite-nitrate, diatoms-algae-hard algae( corraline algae).

Most like these are diatoms that can be the result of silicates in tap water. They (supposedly) can also be leached from silicate based sand.

The first forms are usually brown diatoms that appear as a coating on all of the surfaces of the aquarium. Overtime these will fade away, and start to give rise to patches of other green and red algae.

[edit] Brown algae (diatoms)
Colour: Brown Appearance: brown slimy coating on tank walls, plant leafs. Comes off easily when rubbed.

When introduced to an aquarium, there should be a good supply of common green algae or diatoms (brown algae) present or the fish may well starve. Once acclimated, it will feed from sinking foods such as algae, spirulina, kelp tablets and discs.

Common mechanical filtration sources may include: filter floss, foam inserts, and diatomaceous earth. It is important to rinse out mechanical filter media and replace as necessary.

You can use a diatomaceous earth filter to decrease the number of infective tomites.
Move fish to a clean tank after 7 days. This reduces reinfection by tomites left behind after the initial treatments.

In an aquarium, these mainly consist of diatoms, unicellular microscopic algae. These grow and form a thin film on the decor and glass panes of the tank. Under poor ecological conditions, they can follow from certain green algae.

In the freshwater aquarium, these are usually diatoms. Usually indicates a lack of light or an excess of silicates. Increased light levels will usually make it disappear. Easily removed by wiping the glass or siphon vacuuming the affected area.

Live rock provides algae, cyanobacteria, and diatoms for food, but it also is an effective film algae eater, grazing on other surfaces, such as the sides of the tank.

They love brown algae (diatoms) that is common in newly started tanks and also eat all kinds of soft green algae including green dust algae.

Origin: Cuba. Here the fish inhabit ponds, lakes and streams. Feeds on diatoms, algae, detritus, insect larvae and aquatic vegetation.

Food:
Most of these fish would eat bloodworms, red worms, etc. Diatoms and plankton are also favorite freshwater fish foods.

To date, there is no known cure: the only 'treatment' is the immediate removal of diseased fish to preserve the remaining fish. The use of a diatom filter, which can reduce the number of free parasites in the water, may help.

Algicides are chemicals that can be used to eliminate algal growth in the aquaria. Algicides work on a limited range of algae including filamentous, blue-green, and diatoms.

Algae grows and survives on the same things that the plant life in your aquarium need to live, water, sunlight and nutrients. There are different types of algae such as, hair algae, slime algae and diatomic algae.

The water is clearer, but the wastes continue to add to the bioload of the aquarium until the medium is cleaned or replaced.
Water polishing is accomplished by forcing the water under pressure through either diatomaceous earth or micron media.

These waste products are food for algae; add to that a low-light situation, and you have the perfect habitat for brown algae (diatoms). Just vacuum them off and try raising your illumination level a bit.

a 50 gallon or larger tank for the Tibicen Angelfish. It should have large amounts of live rock for hiding and grazing. It may nip at stony and soft corals (sessile invertebrates) and clam mantles. It will also feed on filamentous algae and diatoms.

In this box, various "sandwiches" of filtering medium can be arranged, e.g. filter wool, charcoal, gravel/shells, or even diatomaceous earth.
Box filters are used primarily for mechanical and/or chemical filtration.

The small round green "dots" that form on the sides of a tank are not algae. These are actually populations of Diatoms, microscopic animals that secrete a hard calcium shell on which green algae grows.
