This 38 grams of HKF Fish Lice & Anchor Worm (AKA Dimilin 25W) is enough to treat up to 10,000 gallons of water one time at a dose rate of 1 PPM for lice and anchor worms. It will destroy all stages of these nasty bugs in four days! It can also work great to destroy mosquito and midges that hatch in the pond and filters! The Active Ingredients: (% by weight)
N-[[(4-Chlorophenyl)amino]carbonyl]-2,6-difluorobenzamide..................................... 25.0% (AKA Dimilin 25W)
This is the "real" stuff also known as Dimilin 25W powder NOT the diluted liquid form! By far the best treatment for lice and anchor worms in Koi and Goldfish. One treatment will usually do the job, but two treatments a week a part can be required at times for heavy infestations. As with all treatments and medications it is CRITICAL to know the exact gallons being treated or you could kill your fish with an overdose. As well if you underdose them the treatment may be ineffective at ridding the fish of these parasites.
Please note the included directions apply to Koi and Goldfish only. If you are treating other species of fish they may require different dosing and treatment protocols.
