Keeping your fish healthy & stay away from ICH

If you see that one or all your fish have become lethargic, their fins have become clamped or you see white little grains of salt all over their bodies, then they're probably sick with ICH (ICK)  As you've read previously in my past blogs, that ICH  to a fish is like us humans catching the flu, and if not treated in time, it can be deadly. There are a number of reasons why your fish became sick with ICH, and anyone that has kept fish for any amount of time, will attest to the fact that they have had fish that eventually developed the skin disease. Many caretakers of fish find it to be more of a nuisance but the truth be told, it's probably one of the main reasons for more fish deaths (very sad) than just about any other diseases out there to affect your fish. If you're anything like me, then you don't want to lose a single fish to any disease never mind the ICH.
I don't want to sound the alarms, but it's extremely important that we address this issue right now and see to it  that we take care of this matter as soon as possible, as it is contagious and will bring down your whole community of fish. - There are several and effective treatments for ICH, but this is the one I always try before adding any chemicals to their aquarium water.
The first thing you need to do is slowly raise the temperature of your tank to around 85 degrees over a period of time (a few hours). Ich will not survive at this temperature and will eventually die off. Make sure you have a thermometer to monitor the temperature, if it goes much higher than 85, you can essentially fry your fish :(  and at 85 degrees  your fish will do just  fine for the treatment time.
Leave the tank at this temperature for 14 days (2 weeks) and continue to feed them as usual. They might not have much of an appetite, so if you see their food still there after 5 minute ensure you scoop it up and out of their tank.  Be sure to keep the tank at this temperature even if it looks like the ICH is gone from your tank. This is because the ich has a lifecycle, the only time the ich pests are visible as white spots on your fish is when it is in the parasitic stage. Otherwise the little buggers will live in your fish tank gravel or substrate or even be free swimming. Leave the tank at 85 degrees for 2 whole weeks (14 days) at a minimum. For hardier strains, you can even leave the tank at that temperature for up to 20 days. - Now if you still see that your fish aren't getting any better because the strain being hardier than suspected, don't panic! There are products as I mentioned earlier that you can purchase, but you need to be so very careful administering them to your tank as they can cause serious problems to your fish and their co-inhabitants. Right now it's important to take care of them as soon as possible. I don't want to sound the alarms but it's extremely important that we address the issue right now. First of all you need to get their tank water as clean as possible prior to adding any chemicals to their tank, and you can do this by suctioning off at least  half of  water in their tank (Be sure to get your nozzle down deep into their gravel and substrate, as this is where the "Little Buggers live) then to ensure that you'll  have their water in peak condition for your freshwater fish as it's suppose to be in, by purchasing  a Fresh Water Kit. I purchased my kit through Amazon, along with the medicine for ICH. I have pictures of  them below to help you decide which is best for your situation.
There are many diseases your fish can get, but I feel ICH is the most intrusive one that I've come acrossed.
