Instructions are horrible, so that's the only reason why I'm giving this 4/5.<br /><br />My 60 gallon planted tank got planaria infestation -- we are talking about hundreds of them crawling on the tank's glass. Funny thing is I have few Discus, tetras, and platys in the tank that supposed to eat these worms! I've tried many things to get rid of them and nothing works other than I managed to kill my Nerite snails with other medications. On Day 1, I decided to put whole packet #1 (250mg) into the 60 gallon tank. I waited for few hours and no changes. But on Day 2, I noticed that the planaria seemed less than the day before, but not much. So feeling frustrated, I dumped full packet #2, WITHOUT changing any water. 12 hours later, I finally noticed that &#62;50% of them started to shrivel up. on Day 3, I put half of the packet #3, and within hours, the planarias were all shriveled up.. So I think it's working. Day 4, all i see is hundreds of dead planarias on the gravel. All the fish and shrimps are alive and kicking. They dont seem to be affected by the meds, but the discus were showing signs of stress. So I changed 25% of water on Day 4, and they looked better on Day 5.<br /><br />This thing supposed to kill Nerite snails, but NOT all snails. I still see few Malaysian Trumpet Snails alive in my tank.
