To suggest that any wood that produces fungus will give you problems is not a statement I agree with. The OP is using redmoor wood, widely used in the hobby.
Manzanita, mopani, red moor plus various others I've used over the years most have produced some kind of fungus at first soaking. All of the afore mentioned are commonly included in aquascapes and in all my years of fish keeping the only time I've heard of fungus killing fish is in this thread. (Every day's a school day) I'm not disputing what others are saying in terms of some fungi being toxic, but speaking from my own experience I've never experienced or heard of fungus seen in aquaria being of detriment to any live stock. In fact I've had set ups where shrimp and snails feast on the stuff... Maybe I'm just lucky...
Ultimately the decision is yours to make based on the advice given in this thread, feel free to do additional research too. But I echo the above and strongly advise against any kind of soaking, wood is porous so whatever you soak it in will end up in the wood and slowly leech back out into the after column.
Fungus grows because there are nutrients within the wood feeding it, eventually they will be depleted and it will no longer have a food source and starve until it no longer exists.
