Thanks guys for all the information,
I went down to Richmond today to check out Big Als there
They do have that box of flatworm exit! however, it is expired..
and the bottle looked like the chemical or whatevers inside, has stained the bottle like rust lol
I couldn't risk my whole tank for just that so I decided to consider Chin_Lee's advice.
Again, greatly appreciate all the information given,
I will have to do a little bit of research on levamisole and make up my mind to which way i wanna go.
BTW, how about the velvet nudi?? J&L's site mentioned them known to clean flat worms though im not sure if it'll survive in my tank before it cleans out all flatworms hehe
