1.009 is what it needs to be to be effective and 6-8 weeks, even when they show no signs of ich, it can still be present in the sand and in the water so give the hypo time to do its job
yeah pretty much... i think... im not sure... anyway im using kick-ick on a heavy infection (yes he still has it) and it has cleared up nearly completely (only about one or two visible spots left.) so its working great!
Use Quinine sulfate from www.nationalfishpharm.com. Safe for puffers, takes about 9 days, very effective. I don't use anything else, and run it 24/7 in my holding system.
