Charles Harrison (owner of the referenced website) happens to hold a Ph.D.
I've purchased from Doc several times without complaint.
Flubendazole and Levaisole hcl are water column dosed.
HA!... i see what your getting at, but I also happen to hold a PhD in public health. Just because he has a PhD doesn't make him trustworthy (I have plenty of colleagues that aren't!). But I definitely believe you all if everyone vouches.
I am going to try the flakes from Angelsplus first and see what happens then probably order from him to eradicate from tank. My first concern is ridding them of the issue to make sure they are able to take in needed nutrients, then i will bomb the tank with the meds from Charles
