Treating red spot disease (often bacterial/fungal from poor conditions) involves improving water quality, isolating sick fish to a quarantine tank, using antibiotics (like tetracycline/triple sulfa) or antifungals, and sometimes salt baths or potassium permanganate for external issues, but getting a vet diagnosis for severe cases is crucial as underlying causes like Aeromonas or Pseudomonas need specific medication, often via medicated food.
Control and treatment
Control of EUS in natural waters is probably impossible. In outbreaks occurring in small, closed water-bodies, liming water and improving water quality, together with removal of infected fish, is often effective in reducing mortalities.
Ammonia burns occur due to high ammonia levels in aquarium water, causing chemical damage to fish, potentially leading to severe infections or death. Key symptoms include red blotches, ragged fins, and cloudy eyes, usually appearing days after exposure to high ammonia.
Just spot dose h2o2 in sections. You don't need to tear everything down. It's going to take a few days for it to die anyways. Every day spot dose a different area and do water changes every 2-3 days. Test and make sure nothing is spiking. Trim off what can't be saved and let the cleanup crew do their job.
Broad-spectrum antibiotics such as tetracycline can be successfully used to treat red blotch disease, provided it is caught early. Some aquarists have found adding 1-2 teaspoons of tonic salt per gallon of water can be useful supplement to antibiotic treatment.
If a fish isn't getting enough oxygen, you'll see it gasping at the surface, moving sluggishly, and displaying rapid gill movements, struggling to take in enough oxygen, often described as "flappy gills," while bottom dwellers may also rise to the surface for air, indicating significant distress and potential issues like overstocking, high temperatures, or poor water quality.
How it Spreads: The virus is spread by grafting and propagation of infected plant material and by insect vectors, such as the three-cornered alfalfa hopper. It is not known if grapevine red blotch disease can be spread by unsanitary equipment (i.e., mechanical transmission).
To get rid of cyanobacteria, make sure you are doing water changes at least monthly, you have fresh carbon and GFO, and your RODI water has 0 TDS.
Chemical-Free Algae Treatments
A regular water change of 50% every week is encouraged to dilute the amount of organic waste in your water. This will reduce the concentration of waste products in your water which algae can thrive on.
Once the ammonia is removed, the fish may recover if the damage is not too extensive. Increasing aeration may be desirable, as the fishes' gills are often damaged by ammonia. This can increase the probability of survival slightly.
When ammonia is present in water at high enough levels, it is difficult for aquatic organisms to sufficiently excrete the toxicant, leading to toxic buildup in internal tissues and blood, and potentially death. Environmental factors, such as pH and temperature, can affect ammonia toxicity to aquatic animals.
One way you maintain proper ammonia levels in your aquarium is to test with ammonia aquarium test strips. Within two minutes, you'll know if ammonia concentration levels in your freshwater or saltwater tank are stable or higher than normal.
Add 1 tablespoon (Tbsp) of salt per 3 gallons of water. You can pour the salt directly into the aquarium or hospital tank, but some people like to dissolve the salt in a small cup of water first. This level of salt is like using Neosporin topical ointment for a small cut (in other words, it's not very strong).
Inspect your fish for red sores on fins or mouths. These are signs of a bacterial infection. White spots or a cottony appearance are signs of a parasite or fungal infection. Watch for your fish gasping at the pond's surface, indicating signs of stress from a lack of oxygen.
Ammonia poisoning can occur immediately or within a few days. Initially, fish may be seen breathing on the surface of the water to breathe. The gills will change color to red or lilac, and may appear to be bleeding. The fish will begin to lose appetite and will eventually lose its appetite.
While algaecide works well to prevent algae from growing in the first place, it's less effective and more expensive if you've got an already green pool. So if you want to go from green to clean QUICKLY, it's time to put away the algaecide and use shock and floc instead.
Although placing copper coins in your bird bath won't prevent algae from ever being able to create an eyesore in your wildlife garden, it will be largely limited if the coins you're using are effectively placed and prepped.
Chlorine is still one of the most effective killers of algae so doing a super-chlorination of 10-20 ppm of chlorine can go a long way towards wiping out the algae. Liquid chlorine is an ideal shock for algae because it is fast acting and does not add cyanuric acid (CYA) or calcium to the water.
Phosphates (PO 4) and nitrates (NO 3 ) are the two thing that need to be most looked at in removing red slime algae. Take the phosphates and nitrates out of the marine aquarium and you will starve the cyanobacteria out!
Visual signs of a bloom include:
Manual/Mechanical Control:
If you are considering how to remove cyanobacteria, physically changing the pond water to remove all water contaminated with cyanobacteria can be an effective method of control.
Treatment of “Red Sore Disease”
If treatment is warranted, potassium permanganate is often effective when administered one time as a bath at 2 mg/l (see IFAS Fact Sheet #FA-23) because of its broad spectrum activity against external protozoa, bacteria, and fungi.
There is no cure for GRBV once a vine is infected so preventative measures need to be adopted. GRBV is known to be graft-transmissible, so the use of virus-tested planting material (negative for GRBV) in propagation is the first line of defence against this pathogen.
Epizootic ulcerative syndrome (EUS), or 'red spot disease', is a disease that can affect many species of fish. Red spot disease is known to be endemic in a number of waterways in NSW. EUS is caused by a fungus (Aphanomyces invadans) and presents as red lesions (sores) or deep ulcers.
