Stop parasites tillverkas av chem-marine och saluförs av salifert i Europa och jag har stor tillit av Salifert och tror inte att de riskerar sitt rykte om denna produkt är verkningslös jag har inte provat denna själv men skulle kunna tänka mig att testa om jag har verkliga problem jag tycker också det är märkligt att 99% här inne inte använder internet till att söka information om saker och ting utan verkar mest sitta här på guiden och fråga. STOP PARASITES By Chem-Marin 8oz. bottle. Stop Parasite is effective and safe when used as directed. First it's necessary to make sure that your tank has a parasitic infestation and not some other type of infection. If there is any question, it's a good idea to use Erythromycin along with Stop Parasites for best results.

One speeds up the fish's natural slime coat causing parasites to detach themselves. Another attracts parasites as a non-nutritional food source. Others speed up appetite and build the immune system. Will not harm internal organs of fish. Note: Make sure you only have parasites; not secondary infection (i.e., bacteria). Directions: Remove chemical filtration: polyfilters, chemisorbs, charcoal, etc. Turn off UV or ozone. You may leave the skimmer running. Add 1 measured tsp. (5ml) per 10 gallons of water twice a day for 5 days. Pre-administer at the recommended rate as needed. Warning: After each application, check pH and buffer (substantial pH drop may occur).
