Formalin (updated 6-30-22)
What It Treats – Temporary relief for Marine Velvet Disease (Amyloodinium), Brooklynella, Uronema, Flukes (Monogeneans), Black Ich (Turbellarians). 100% eradication of these diseases is possible through repeated baths and/or In-tank treatment.
How To Treat – In order for Formalin to be fully effective, the product you are using should contain 37% formaldehyde + 10-15% methanol. There are very few "aquaculture approved" formalin products on the market, and they can be expensive + difficult to buy due to various regulations. Parasite-S (MSDS is here) can be purchased from Syndel USA: https://www.syndel.com/parasite-s.html
However, you can also use this Formalin product sourced through Amazon: https://www.amazon.com/dp/B00GOAA6G8/?tag=humblefish-20
Just keep in mind that formalin typically only has a 6 month shelf life, so don't stock up on it!
Also, formalin should always be stored + transported at temperatures above 40°F (5°C).
Usage - The below dosages only apply to fish being treated in a marine environment above 70°F/21°C:
1) In-tank treatment: 1 ml per 10 gallons (or 2 drops per gallon) daily in a bare aquarium for 7-10 days. This produces a concentration of 25 ppm. Dosage may be cut in half (12.5 ppm) for sensitive species or extremely sick fish which may not be able to tolerate a "full" treatment.
2) 30-60 minute bath treatment: 1 ml per gallon or 20 drops per gallon premixed into the water. This produces a concentration of 250 ppm. Dosage may be reduced to 200ppm (16 drops per gallon) or even 150ppm (12 drops per gallon) for sensitive species or extremely sick fish which may not be able to tolerate a "full" treatment. Treat for a maximum of 60 minutes if the fish seems to be handling the bath fine, but cut it short (30 minutes) if breathing becomes too heavy. The bath is best done in a large glass bowl or container, but a food grade plastic bucket is fine as well.
Anytime you use formalin it is extremely important to vigorously aerate the water, especially when doing the bath treatment. This is because formalin has a tendency to rapidly reduce available oxygen in the water. You can use an airstone (or multiples) cranked on high, or a powerhead pointed towards the surface of the water, to increase gas exchange (which provides more oxygen).
Pros – Treats or provides temporary relief for a wide range of diseases. In some cases, formalin can “buy you more time” until a proper treatment can be done.
Cons/Side Effects – Formaldehyde is a known carcinogen. Therefore, precautions must be taken when using it. Preventing your skin from coming in contact with it by wearing waterproof gloves and not breathing in any fumes by wearing a face mask is highly recommended. Formalin also can be harsh on the fish’s gills and will quickly deplete oxygen from the water. DO NOT USE if a fish has open wounds. In some areas, the purchase of formalin is prohibited.
