Levamisole

[Austin1234]

Update, treated at 4:30 yesterday about 8 pooped out a huge long squiggly white worm. Levamisole has effected the ray though. all night it didn’t move much at all very still with front of disc up like to get more air. This morning is moving about a lot more but ammonia is starting to come up. Have an ammonia alert on the tank and it turned to alert. anyways of course bottle 2 was empty from test kit so wife is making run for new. For being ray safe it sure is sketchy. I dosed according to loach’s.com 2ppm so I know it’s not overdosed. It’s been 15 hrs can I change the water and get it out early or should I push for the 24hrs. Qt. Tank is well established and have not had any ammonia issues at all till now.

I would wait for twenty four hours.

Not sure why ammonia should increase, unless it killed a very high load of parasite. In which case, it really was needed.

Remember to treat again in seven days and fourteen days.

Nitrates shot up also… did a 80% wc before treating last night. I did end up water changing a little early but it was still 17-18 hr treatment.. I’ll re treat again in a week. This is stressful! Why does it seem to affect rays so much?? My last ray that died during treatment made sense…because it was pretty bad off. This one I noticed the warning signs and checked the poop with microscope . Was hoping it would minimally effect the ray but it clearly bothered it and made it very inactive and all my parameters went off. Best thing I can say from all this is just because you qt for 3 weeks don’t mean everything is good.. I should have been more alert that the ray that died was hit and miss on food and never put it in a grow out linked to other rays

So post treatment got another poop sample and appeared to be white looking worms with naked eye and tons of eggs under the microscope. If I’m identifying correct I’m guessing hookworms? Still fighting .25 ammonia but no higher. Tank is bare bottom with sump haven’t noticed mass numbers of worms dead causing the spike

Update filter definitely was effected could not keep ammonia from climbing. Added some more established media and ammonia is back under control. Don’t know why it happend but it did. Also found out a lot from

I found some crazy things last night almost everything in the video.. and had I not found the video explaining them I would have probably full on panicked and nuked my tank. Figured I’d share what I found incase someone else was curious. Levamisole may be ray safe but it is not without caution and in my case it effected the rays and bio filter a lot rather directly or indirectly I’m not sure but unless your sure you have identified your problem I would not use it.

I still do not understand - from the video or otherwise - why levamisole would have affected your bio media.

agreed. I didn’t find any answers to that from the video just identified what I was seeing. But it most definitely crashed my bio filter. Tank is bare bottom so there was no excess waste causing the spike. Filter sock was changed after treatment even added an air stone to the sump.

I use L often, and have never come across this. Different locations have got varying brands and formulations.

This is what I use, at 24cc/cubic metre.

The levamisole also irritated her disc and made it turn red pink on the bottom . This pic was a hour or 2 after treatment began. before the ammonia spike. I did a quick Google search of levamisole ammonia spike and it’s definitely not just me this has happend to. Not sure what to think about it. I dosed light split a 1/4 tsp .5 gram I want to say to 60 gallons of water. Used the prohibit, it was on the list @ loach’s.com.

So I sucked it up and bought a decent microscope to try and learn as much from this as I can, and unfortunately looks like i was right and another ray may have been infected with worms.it seem heathy without any symptoms yet.. I managed to get a poop sample (only downside is I know it wasn’t fresh probably 6hrs old) I clearly can make out worms and best id I can manage tells me they are nematodes. I have levamisole on hand ready to go but am scared to use it. I know it’s effective.. just want more testimonials and pointers to treat safely. Or maybe what I’m seeing isn’t anything to worry about???

What kind of Microscope. I’m in the same boat and not sure if I want to buy a used microscope from 1 of the Big 4 name brands or just grab a Swift 380T and call it good enough.
