Also, with ich--especially if you have a UV--they settle on the substrate after they drop off to breed (hence, the common cycle of better one day then bad again, etc), so if you can get some flow moving over the bottom (obviously, in a very lateral way and not pointing down at it, which would just stir it up), then it will keep the parasites in the water column where they are more likely to be exposed to the UV.
A good soak regimen is extremely helpful too. I use hikari freeze-dried spirulina brine (very healthy just by itself), which acts like a sponge and actually absorbs what you soak it in. For me, I use BWA Garlic Power (which also has Vit C in it), BWA Vitamarin M (has a whole bunch of vits, including B's, zinc and C), and BWA Amin Omega (has amino acids, and omega 3 & 6 [HUFA's]). Tips: be careful not to crumble the brine, as it is very fragile in its freeze dried state. This way, after it absorbs the soak stuff, it retains its natural state and when you feed it (I just use the tip of a fork and lower it in front of a K4, which immediately disburses it throughout the tank).
You can do the same thing with pellets and seaweed, but you'll need to combine your soak ingredients first, then apply to seaweed, spread then let dry / make a small puddle on plate and roll pellets over until absorbed and then roll to dry part of plate to dry. These are also really effective because the nutrient don't rinse off when you put the food in the water. With freeze-dried / soak method, some of the surface soak will rinse but the absorbed won't.
This is an extremely effective method of getting very high nutrient content to the fish in a single feeding. Just like people, when you're sick, nutrition is a big part of recovery or even fighting off a bug before it knocks you down. I've found fish, especially tangs, to respond in very much the same manner. For what it's worth, in 10 years, I've never lost a tang to ich using this philosophy.
