A dip of 8 grams KMN04 per 40 litres of mid-seventy degree water can be used but for no more than 2.5 minutes. Precise measurement is critical. Aerate. This dip requires several containers as well as an uncontaminated pond or q-tank to place the treated specimens. Pre-dip and post-dip containers are a must. Make sure they can be covered securely. This is a bit over 200ppm! Dips only work if the container (pond) the treated fish are being returned to is parasite free.
A gram scale is required to measure this chemical. Please calibrate it frequently.
Any dechlorinator or hydrogen peroxide will reverse this chemical. Make sure you have enough to neutralize at least twice the amount used.
ProformC or Formaldehyde and Malachite Green:
This treatment is safe at temperatures of 55*F to 80*F. FMG is effective on most microscopic parasites except flukes. This is a poison. It is dosed in amounts which will effectively kill the parasites without killing the host. Overdosing may damage or kill your fish. Formaldehyde is generally available from farm supply stores. It is 37% formaldehyde and 11~12% methanol. Commercial mixes such as ProformC are available from pond and koi suppliers. While it is a bit weaker it still works well. It also gives the end user a larger margin for error. It is 22% formaldehyde and about 7.5% methanol.
The following treatment is "off label": Two treatments, day one and day three. No water changes. Then a third dose combining ProformC and Praziquantel, AFTER a 50% water change on day five. Another treatment should be considered after seven days AFTER a 50% water change. See the paragraph below for Fluke Specific treatment. A small percentage of salt in the water will not affect the treatment or the fish. This treatment is for all parasites and it is temperature/life cycle dependent. Flukes can take 30 days to eradicate if the water is in the low sixties. This takes several treatments. Warmer waters reduces the time frame.
