I also have heard several things about slime coat enhancers.
1) Some act by irritation.
2) Some are goo that sticks to the fish including the gills. Not good, IMO.
3) Healthy fish do not need slime coat enhancers. A good rotating diet, healthy tank and so on go a long way to helping the fish to develop just the right amount of slime coat. Not too much, not too little.
About the only time I use anything like that is if a fish needs to be handled, for example to hand remove an external parasite. Then, the fish is in a quarantine tank, and anything I use to help that fish will not bother the other fish.
I use Chloramine Buster by Clear Pond.
Heavy metal detoxifiers are often chelators. This may interfere with some of the trace minerals that plants use. Chelators hold onto different metals with different levels of attraction. Fortunately for us the plant fertilizer minerals (calcium, iron, magnesium) are lightly held and the more toxic minerals (lead, mercury, zinc, cadmium) are more strongly held. I would like to think that a gravel vac (or at least as close as we can get in a planted tank) is enough to remove the chelated minerals. I do not know, however. Do the chelated minerals stay near the top of the substrate?
Some chelators are light sensitive. A UV sterilizer will often break down the chelation material, releasing whatever it held.
