The Late Jorgen Scheel (famous ichthyologist and killifish breeder) writes about using a low dose sugar solution in his Killiefish tanks in his landmark book, Rivulins of the Old World.1968, TFH Publication. |
"Most rivuline individuals take much food and it is often not to easy to keep down the concentration of waste products. Also, these fishes prefer food rich in proteins and their waste-products simply cannot be taken up by the plants because of the deficiency of CO2 and an artificial supply of this gas should be given. The usual system, with fermenting sugar-solution in a separate bottle for each tank, is not very practical for the killifish fancier. When much care is taken, another system might be used. Prepare a 5% solution of sugar in water (about 6 ounces of sugar to each gallon of water) and add 16 cc. of this solution to each four gallons of aquarium water (1 cc. to each liter). Best results are had when the sugar solution is stirred into the water and bad results are usually had when solid sugar is added directly to the aquarium. This method is very useful when the possible bad effects are understood and counteracted. First the sugar is converted to carbon dioxide and alcohol, which do little harm. The alcohol is converted into acetic acid and the oxygen needed for this process is taken from the sulfates, resulting in the production of the poisonous hydrogen sulfide gas, which is very harmful for fishes. I have used this system in fifty tanks for more than two years without killing a single fish. The sugar solution usually is added to the tank every two weeks."
I think its worthy of a side by side comparison, and finding the ideal dose. Anyone interested?
Anyone else intrigued?
