Size and type of organism: Theoretically UV radiation can kill viruses, bacteria, algae, and protozoa. In general, larger organisms, such as protozoa, require a higher dose of UV radiation than smaller organisms, such as bacteria.
Bacterial diseases
Diseases caused by bacteria. Bacterial diseases fall into two categories, those that affect specific areas of the body (localised) and those that affect the entire body (systemic).
Bacterial Infections
These usually appear as red patches or streaks on the body of the fish, or sometimes appear as damage to the fins of the fish, such as "fin rot". Bacterial infections are almost always due to poor, declining water conditions.
Bacterial Blossom - Often cloudy water doesn't appear the instant an aquarium is set up. Instead it appears days, weeks, or even months later. In these cases the cause is usually due to bacterial bloom.
Bacteria in the nitrogen cycle
Rarely found in open water (around 1% of the total count), bacteria colonize essentially the floor and the decor. They feed on nitrogenous compounds in the water, extracting the oxygen from them.
Bacterial and Fungal Infections
The most common health problem among aquarium fish is infection from bacteria and fungus. The primary culprit is usually bad water quality.
Bacteria: the good bacteria and other microorganisms that degrade fish waste, ammonia and nitrite all require oxygen to survive and function.
Bacteria: Small single celled organisms from the kingdom Monera. They are known as prokaryotes, which are classified together because they lack nuclear membranes. They are the most primitive living beings.
Bacteria for seeding a tank can be obtained by:
- Getting a commercial product (Fritz-zyme, other commercial products).
- Backflushing a sand filter.
- Squeezing out sponge filters.
- Siphoning from an undergravel filter.
Bacterial Infections
Recognizing bacterial infections in your fish isn't always easy. You may see red blotches, or streaks on the fishes body and it may also appear that the fins have been damaged similar to fin rot.
cyanobacteria - Cyanobacteria is commonly referred to as red slime algae by hobbyists although it is not really an algae. It is a bacteria. Poor water quality with excessive nutrients are the usual causes.
Cyanobacteria: Organisms that can form large colored mats. They are usually blue-green in color. Cyanobacteria is commonly referred to as red slime algae by hobbyists although it is not really an algae. It is a bacteria.
Cyanobacteria and Iron
It has been suggested by some hobbyists that iron additions to reef tanks may drive the growth of cyanobacteria, and that one should not dose it for that reason.
Bacterial diseases (gram negative)
DISEASE BACTERIAL - caused by several species of rod-shaped, motile, (="mobile"), Gram-negative bacteria. Most species belong to the Aeromonas genus.
Bacteria are the most important part of an aquarium filtration system. Various species feed on ammonia, a highly toxic substance produced both by fish metabolism and by decomposition, which they convert to nitrite (still quite toxic).
Bacterial infections are commonly limited to one species of fish. Remember this, because it is a great help in diagnoses. If numerous types of fish are dying, the cause is almost definitely NOT bacterial.
Bacterial and algal spores, resting, or vegetative forms are everywhere; they may even be carried by air currents. Unfortunately, the two species we want for oxidation of ammonia to nitrate have no spore forms.

Bacteria
Bacteria have a similar food value to fungi, but they generally reproduce faster than fungi and algae, although the food value doesn't tend to be as high.
The bacteria grown will then digest the ammonia from waste, turning it into Nitrite.
The bacteria are necessary to help in converting the excrement and urine of the fishes and waste food into harmless by products which the plants use as fertilizer for growth.
This bacteria is associated primarily with the salmonid species of fish, although as time passes it seems more species fish are susceptible than originally thought.
Cyanobacteria - Commonly known as "Red slime algae" which is not technically an algae. It is a bacteria which is normally caused by poor water quality and excess nutrients in the water.
Cyanobacteria - red slime algae - this is probably the worst kind of algae you will encounter in your tank,
and is directly caused by very high NO3- levels, and usually indirectly by a change in lighting at the same time.
This bacteria needs oxygen to perform its task of converting Ammonia into nitrites then into nitrates. Here is a couple of equations that quite simply express how this is done.
Anaerobic bacteria form in the bottom depths of the substrate and in the water below. As anaerobic bacteria cultivate, they remove nitrates. Anaerobic action produces a fair amount of heat. The heat warms the water layer below the gravel.
Beneficial bacteria start to reduce ammonia first. At the beginning ammonia will be produced faster than the bacteria can reduce it to nitrite.
The largest bacterial populations in a tank are found in the filter. Therefore efficient filtration is vital. A vigorous cleaning of the filter is sometimes enough to seriously disturb the biological balance of an aquarium.
Beneficial Bacteria: There are useful bacterium in your aquarium, like Nitrosomonas which will convert ammonia to Nitrite. See The Nitrogen Cycle
Biological filtration: This system breaks down any toxic compounds, usually Nitrogenous toxins.
Remember that the bacteria break down the ammonia into substances (first nitrite, then eventually nitrate) that are merely less toxic, rather than non-toxic.
Monos are prone to bacterial infections like scats if not kept in brackish to marine conditions.
The disease causing bacteria can be from either of the above group. And the nitrifying bacteria are Gram-Negative.
To kill bacteria we need Antibiotics. There are three types of Antibiotics: ...
Not only provide an anti-bacterial effect, but help fishes produce body slime to protect themselves from infection and create an essential osmotic barrier so they do not dehydrate. Make sure it is dissolved before adding to your aquarium.
While necessary for some things such as bacterial reduction of nitrate to nitrogen, these areas can also produce hydrogen sulfide and other undesirable substances. aragonite The substance that makes up coral skeletons and coral sand.
Shouldn't this kill the bacteria and sterilize the tank so my fish don't get sick?
Microscopinc benificial bateria live in the filter system, on the top layer of gravel, ornaments and in the aquarium water.
The water should be clean and relatively bacteria free. The tank should be arranged in dark colors and floating plants should be used to diffuse the light. Discus may remain hidden all day if bright light is used.
Even live snails can harbor parasites and bacteria. It's a good idea to quarantine such animals before placing them into the tank you've worked so hard on.
The oxygen is also used in plants respiration and other invisible creatures from the aquarium, such as bacteria.
Needs a place for beneficial bacteria to live and grow: When you set up your aquarium you will be using a filter of some sort which will provide a home for this bacteria.
This process is to start the cycle off (the initial bacterial growth) and keep the bacteria alive by feeding them ammonia at the correct concentrations in the tank water.
5) After about a week you can start to test for nitrite in the water.
This makes it very easy to clean and prevents shock to the aquarium since you can replace the media one at a time, allowing the bacterial colonies to propogate from the old media to the new.
Many plants, fish and helpful bacteria can suffer as a result of using medication. The following list provides general points that support disease prevention:
Choose only healthy fish, avoid purchases from aquariums containing sick fish.
Old/dirty water is usually the most rich in these nitrifying bacteria (Nitrosommonas sp. and Nitrobacter sp.) The more the better. Start filtration, let the water settle for a few hours, and then experiment with adding fish.
Eggs fungus as a result of bacterial attacks, which results in the shells damaging. The fungus is the second infection, because it attacks damaged eggs.
Infusoria feed on bacteria and are already present in low levels in an aquarium. The trick is to grow enough to supply young fry. If you have access to pond water, this will suffice.
Nitrsomona bacteria convert the ammonia into
toxic nitrite (NO2). Nitrobacter bacteria then breaks down the nitrite into non-toxic
nitrate (NO3). This nitrate is then removed from the aquarium by performing partial
water changes.
...
Many successful breeders recommend bare bottom tanks, but I was concerned with reports that loricariid fry could be affected by the bacterial film growing on the bare glass. The tank was filtered by a 500lph external Eheim.
They improve your water quality by providing excellent surfaces that can be colonized by beneficial nitrifying bacteria. They directly remove some compounds from the water.
