Ja så blev det min tur til at være uheldig, min store flotte Acropora har fået STN

i den anledning har jeg været ude og købe en gang Coral Protec, da der står på det at det skulle kunne behandle både RTN og STN.
har copypaste brugs anvisnig
Coral Protec is effective in expelling the following parasites:
Acropora Eating Flatworms (AEFW),
Montipora Eating Nudibranchs,
Zoanthid Eating Spiders,
Red Flatworms
and performs very well in the treatment of Rapid Tissue Necrosis(RTN), Slow Tissue Necrosis (STN) and Bacterial Infection.
One 20ml bottle will treat 40 liters (10 1/2 gallons) of water in dipping container
Safety:
Keep out of reach and sight of children.
Avoid skin contact, wear suitable gloves. In case of skin contact, wash with plenty of water.
If swallowed, wash out mouth and drink plenty of water or milk. Consult your doctor and take the bottle / instructions with you.
If contact is made with eyes, wash thoroughly with cold water. Consult your doctor and take the bottle / instruction with you.
Shake bottle well before use. This product includes oils which will settle out with time.
Never add Coral Protec directly into the aquarium.
Make sure when dipping corals to use the water at the correct temperature
Directions for use:
Add 0.5 ml (syringe included in the 20ml packaging) of Coral Protec per 1 liter (2 ml per gallon of aquarium water) of saltwater from the aquarium in a separate container. Mix well. For additional potency, freshwater dip can be used. Be careful and buffer the pH values to match your aquarium water when performing a freshwater dip!
Use a small powerhead to keep the water moving and place the coral in the container. If you do not have a powerhead, gently shake the coral in the dip.
Keep the coral in the dip for 2-5 minutes depending on severity of problem. Observe the coral during treatment for evidence of adverse reactions such as excessive sliming.
After 2-5 minutes, remove the coral and discard the dip. Rinse coral with clean aquarium water and place it in the aquarium
Do not reuse the coral dip, as expelled creatures whilst dipping may release toxins (flat worms).
Clean syringe and / or container with freshwater after usage.
Det er alt hvad der står, jeg har fulgt anvisningen til punkt og prikke. Nu er spørgsmålet så må jeg gentage behandlingen, og hvis man må hvor lang tid skal der gå, før man må behandle igen ?
