I hope there is no "secret" as to why no one has posted the PP dip, other than that perhaps they don't have it written down somewhere. It is critical that you have an accurate gram scale. You need 8 grams of PP to *exactly* 10.5 gallons of pond water: this is a 200 PPM dip. Have 3 tubs: one is a holding tub for the fish (pre-dip), one is for the dip, and the third is a rinse tank. All should be well aerated. Take the fish from the holding tank, place into the dip tank - TIME FOR EXACTLY 2.5 MINUTES - remove to the rinse tank to recoup. If the fish rolls, remove it promptly.
Please be advised that this is a "cure 'em or kill 'em" procedure: if the fish is not too weak, it will survive and be parasite free. If it's too weak, survival is not, shall we say, optimal. Look for areas on the fish that are brownish, tea-stained: those are the nuked parasites.
As far as dropsy is concerned, survival rates are based on the cause. If the gills are pale, the fish has become anemic due to kidney failure and the prognosis is pretty grim. Most of the time, the kidney problems are a result of internal septicemia (bacterial infection). However, there are times when the fish will simply absorb water, usually due to a large, open ulcer - and the kidneys simply have a hard time getting rid of the extra water. If you can raise the salt level for the fish to, oh .6 or so, the extra salt will help the fish get rid of the water. This only works in the case where the fish has absorbed the water through a wound, and it is NOT the result of kidney failure.
Antibiotics when a fish is dropsied is contraindicated. That includes medicated food. Most of the antibiotics have an adverse affect on kidneys - so the last thing you want to do is further stress the kidney.
The use of injections and antibiotics are used too lightly: there is a snow-ball effect from their use. Antibiotics do not differentiate between "good" bacteria and "bad" bacteria; its use will frequently (as in almost always) affect the "good" bacteria in the gut that are required for the digestion of food. Then the fish is subjected to a period of time - very similar to coming out of winter - where it needs to be "babied" food-wise until the bacteria can return to normal.
I hope I have not overstepped my boundaries on this board and that the information above will be helpful. If not, then someone should remove this post.
