i love all the input how can one go wrong on this site

You can go wrong if your are not good at soritng the wheat from the chaff.Here is my response to an earlier thread on this subject.
When ich shows up you have a basic choice to make in the context of the situation. Treat the fish and leave the display fishless for a minimum of 6 weeks or don't treat the fish.
The only way to treat the fish is with copper, hyposalinity or the tank transfer method.
There are no other proven treatments. There are anecdotes and theories,placebos , equipment,elixirs and potions supported by the fact that some fish do survive cryptocaryon irritans (ich) and develop partial immunity without treatment.
Some of the non treatment actions frequently taken include the following:
Lysmata amboinensis(cleaner shrimp) . They preen the fish. Many believe they eat ich. Gut studies have not supported the idea that they eat this protozoan,however. Some note that the white spots are exit wounds and the eating observed is actually the shrimp picking at the exposed flesh.I have them but don't expect them to help too much if at all against ich.
Garlic and more precisely the active ingredient in it ,allicin, is widely believed to enhance the human immuno system. It is a big leap to assume it has the same benefit when administered via soaked food for marine fish but it might. However, allicin is only active for an hour or two after after the garlic clove is squeezed. The prodcuts on the hobby market are preserved concentrates which makes their value against ich even more dubious. ( Garlic Guard by Seachem does claim to contain allicin)Some have begun to question wether prolonged use may be harmful to the reef. None of the manufacturers of the hobby products actually claim it will enhance the immune system of fish or prevent or treat parasitic infections. I use it lightly.
UV sterilizers. They only effect what passes through them. So in the best case they would only effect parasites that were sucked in not those on the fish nor the cysts. Even then the protozoan parasite is relatively large and it would take a significantly oversized uv to kill them. They are very good tools for water clarity and killling of smaller organisms such as bacteria and phytoplankton.I use them.
Diatom filters. This is mentioned once in a while as a method to screen out the swimming ich. It may have some promise and I would like to learn more about it.
Keeping the light on for several days. I think this does more harm than good to your tank and will not based on my reading stop the ich. It is based on the idea that the parasites usually hatch at night which is true ,but when there is no night they don't seem to have a problem hatching in the day.
Maintain good water quality; provide nutitious diets, keep stable ph ,salinity and temperature and minimize aggression are all good things to do even if ich is not in your system but when it is they are even more important since your fish even though not showing signs are likely a bit weaker than they migh be otherwise.
Don't add new fish for 11months. This is the time it takes for a single ich strain to expire. since it has a limited number of times it can reprocue (34).
Good Luck
