Here's what I would do. I would stop replacing any filter media! I know some people like biowheels but I am not convinced they are useful. Marineland products are pretty 'meh..' to me. I would not count on the biowheel to preserve your bacteria, hell two of the Marineland filters I've owned the biowheel never even spun correctly or with any consistency. The flossy stuff is actually what is holding the good bacteria, at least the vast majority of it.
Second thing is carbon is useless (seriously 100% useless in modern aquaria, becomes inert after a few months..). If you can find filter media that is simply sponge based to hold bacteria/detritus you will be better off (again not a fan of Marineland).
Pick up some SeaChem Prime, it is my favorite water conditioner. It's very concentrated (a little bit goes a long way) and it has the extra benefit of converting Ammonia into a much less toxic Ammonium, that should take some stress off your frog until your cycle is complete. Also pick up some Stress Coat by API, it's another excellent product for your frogs slime coat (which protects it from infection).
If you have any more questions feel free to ask.
