Please please please remove your frogs before the treatments. It is highly unlikely that your frog has ICH. Usually the mucus membrane on the frogs protects them from that. However, Ich meds usually contain copper which can be quite harmful to your frog.
Better to add a small amount of salt and increase the temp on your tank than use ich meds. It will save your cycle and cause less stress to your fish. It takes around two weeks but there are a ton of articles out there to learn about treating Ich to maintain a healthy tank. I have been there are done it with our fish tanks here at home. It will be sure and kill off all of it and you could reintroduce some healthy fish or your frogs back in. Keep in mind that the salt isn't all that great for those froggers either.
Still I would remove the frogs and house them in a bucket if needs be. I use a couple of home-depot 5 gallons when I need to quarantine.
