Let me guess, u're not from Tropical Malaysia eh? I find that ick is not/hardly a major problem in Malaysia simply because of the temperature. We have almost year round temps of 30degrees C and at that temperature, ick just doesn't exist.

Anyways, here in Sydney I get ppl having major battles with ick, and when I ask that they crank up the heat to 30degrees C they look at me funny and say that 's too hot. Most tropical fish are farmed in South East Asia, and temperatures here are between 30-34degrees C all year round!

Anyways, my advice is to crank up the heat and add a propriety ich remedy which should contain malachite green. No feeding while on medication and ich should be cured quickly if caught early enough. No major dramas with ick..
