Which One Is Better (your Point Of View)

I've used Ick Guard II and Quick Cure. I would prefer Quick Cure, even though it may give your silicon and your tube to your airstone a light blueish tint. That may go away after time, I really don't notice it...I just looked at it since it says it may do that on the bottle and saw it was barely blue colored. I don't even think anyone else that looks at it even notices it...and it did the trick, so I guess it was worth it.

goodluck w/ ich probs.

Oh yeah, I have a white sponge in my AC filter, and it turned that blue also....but who cares, you never see that except for cleaning time anyway.

I`d go with Quick Cure based upon my experience.
