Ich in Goldfish Tank

[justupgraded15]

I have had ich and fungus in my 10 US Gallon golfish tank for 4 weeks and it is not going away. It started on my orange fantail, and now it has spread to my other three goldfish. I also have 2 otocincluses and a cory, but they seem to be unaffected. The goldfish are behaving and eating normal, but the ich is spreading. I have been trating the tank for three weeks with Rid Ich, and combonation of Formaline and Malachite Green that treats ich and fungus. I have had wonderful results with this before, but this time it is not working. I have been putting Rid Ich in at 5mL or 1 tsp. a day.
All the water qualities are fine...
Ammonia=0
Nitrite=0
Nitrates=>1
I keep the temp between 72 and 76. Someone at an LFS said to raise the temp to 78, but I know that is the max safe temp for goldfish. I do not need to have Ich explained to me, because I am pretty knowledgeable about fish illnesses. I am just stumped here and am curious if I should increase the dose of Rid Ich or try something else.

Thanks,
J.R.

Are you vacuuming and doing water changes as well. If not give that a try as it will help reduce the amount of ich in the tank by removing the cycts from the bottom and removing the free swimming protozoa from the water. HTH

Yes, I did a water change about 4 days ago.

while you have ICH you should do daily 10% changes and clean the gravel well as you do it. This will help in the control of the ICH as it will get them at each stage of deveopment. HTH
