Dealing with my first ever capillaria infestation. Yuck. Lost one fish, but think the other two will pull through. Tank is planted and has a lot of nooks and crannies, so getting these dead worms out of here is a bear, to say the least. I looked everywhere for the right approach and PraziPro was not it. After that failed, I went to levamisole which is really showing results.
Here is what I am doing
2ppm for 24 hours in total blackout followed by a close to 100% water change, then repeat weekly for 2 more doses. After each dose, there is a LOT of cleanup. Will let you know how it turns out. I am also feeding levamisole medicated flakes. Fortunately they are both still eating.
In my case 2ppm is 1 gram of Levamisole HCL (drench solution) dissolved in water to treat 120 gallons. A lot of stuff I read was dosing up to 13 ppm! Just go ahead and get a little scale if you don't already have one. They are cheap when you don't need them and priceless when you do. I think this is the one I have: https://smile.amazon.com/LuckyStone-Portable-Electronic-Weighing-Stainless/dp/B00LL0Z1LQ/ref=sr_1_49_sspa?crid=1EQ4B3WWSIIEE&keywords=pocket+scale+.01g&qid=1553451483&s=gateway&sprefix=pocket+scale%2Caps%2C170&sr=8-49-spons&psc=1
This adventure has also taught me that guaranteed snail free isn't a guarantee of a snail free tank. Killed one a month ago and two today. I also learned that levamisole doesn't faze them unless that is why they came out of hiding. Might have been the blackout, though.
And I carried 2 garter snakes out of the house this morning. One greeted me getting out of the shower and the other was hanging out around the RO barrel.
Yes drive back her to get fish, see the grand kids and hang out with your fish buddies.
