For ick, treat with salt and heat, as indicated here:

Also, try and figure out why the fish has ich, so that a re-infestation of this parasite can be avoided. Do you quarantine new additions? Feed live "feeders" without quarantine? What is the temperature in your tank?
Water clarifier is fine, but it would be better to figure out why the water is cloudy. If you'll answer these questions, I think we can figure it out. That will be cheaper than dumping in chemicals!
How long has the tank been set up?
What are your ammonia, nitrite, and nitrate levels?
What type of filtration are you running?
What size tank, and what fish are in it?
What are you feeding?
Is the tank near a window/getting a lot of natural light?
How long are you leaving the lights on?
Sorry for so many questions, but I'm a firm believer in fixing the root of the problem, rather than taking what may seem to be the "easy" way out, only to find that you're hurting your fish or wasting your money!
