Comments: Use as directed for best results 3 month treatment. If keeping acro in your system its best to use after the 3 months to keep this going in your system. I completed the 3 month and now dosing 3 days a gallons 180....SPS..... 10ml. FWS works and it's an advantage to all corals in a reef! A hint of a vinegar smell....I dunno what the aefw don't like but this works and I like it!

Comments: I decided to give this a shot so I wouldn't have to nuke the entire flatworm population in my tank in one heavy dose. I read all the reviews of how great the product is and how well it worked. About a month and a half ago I noticed flatworms in my 20 gallon tank. I began dosing 1 1/2 the recommended dose and have done so now for just over 45 days. The population of has not increased since I started the product but exploded to the point that they are every where. I know the manufacturer says it takes three months however, I can't imagine the population in another month and a half from now. It looks like I'm going back to Flatworm Exit after all!

Comments: This product takes 3 months. It is in tank treatment. After a couple days corals begin to color up. If you have AEFW get this product!

Comments: I was getting real frustrated with my flatworm outbreak in both of my tanks. I tried the "natural" method of using Arrow Crabs, Wrasses, etc. to no avail. Either the crab would end up dead from a predator or the Wrasse would choose not to eat my flatworms. I did not want to go the "chemical" route as I have heard horror stories about toxins being released from the dead flatworms. Imagine my THRILL - when one of my favorite supplement developers (Korallen-Zucht)have come up with their own flatworm stop. I immediately purchased this and began to treat both tanks. Within 2-3 days, I noticed a decline in the flatworms. It's been a couple of weeks now and they are all but gone!!! It's natural and it's SAFE!! I recommend this with gusto! Once again - Korallen-Zucht came through with flying colors!

Comments: It's slow, but it works! I double dosed and It took about two months to get rid of a booming infestation of AEFW. I didn't lose any colony. Thomas Pohl advices to stop dosing brown organic iodine and mix the FWS with K-balance before adding to the tank (I guess other potassium supplements would do). The product by itself seems great. Polyp extention and general health of corals are improved after dosing for some times.
