Hi guys,
So I've read your threads about using levamisole to de-worm the fish .. got out to Petbarn and get a bottle of Avitrol Plus, with states Active Constituents: 10mg/mL Levamisol Hydrochloride equivalent to 8.48mg/mL Levamisole base 2mg/mL Praziquantel.
I put in about 50mL of this .. for a 400 L tank.
Now I got something like a bacteria boom .. and the fish is surfacing for air ... :roll: they don't look too ill except of that...
Any idea !?? Is that "Hydrochoride" the HCl acid ?!?! and it killed the bacteria (both good and bad ) ???

avitrol is a bird wormer and usually has a syrup base

the sugar or whichever carbohydrate molecule has led to a bacterial bloom

large water changes
turn the temperature down slowly a few degree below what you normally use
and increase aeration with air stones etc

Welcome to the forum Fishontherun.

If you read through the posts on Levamisole, you will see several warnings about using bird wormers that contain sugar or syrup.

The syrup is added to make it more palatable to cage birds. We try to get the one called Big L Levimasole Pig and Poultry wormer which has no syrup added.

Or go to your local vet and get the pure Levamisole powder, you'll need digital scales as you only use 1.14grams per 100 litres of water. I've found it to be very inexpensive, around $50 for half a kilo.

If the live stock place will allow you to open the bottle and it smells sweet this means it has a sugar or syrup base and not to be used.

Levimisole reported to be fine with BN, providing the dosage is not excessive. I've not dosed BN with it though (no need for such so far).

Just don't get the one with sugar, as the post above warned.
