Hex-shield questions

[Sharkbait19]

Hi,
I am wondering about the New Life Spectrum Hex-Shield food. I am going to buy it for a parasite problem in one of my FW tanks, and would like to treat my clownfish as well, in case of any parasites they have (specifically hexatima worms, which I’ve noticed symptoms of). I have a few questions:

- is there a “dosing amount” per fish? Is it possible to overdose?
- do I add it with their current diet or substitute it entirely?
- are there any ill effects I should know about?
- what’s the effectiveness in your experience?

Thank you in advance!

I haven't seen any issue with it when I used it on fish at work. We have that and ich pellets laying around. I believe the instructions say to just feed as much as the fish will eat in a sitting
