if you live in Australia you should only have chlorine in the tap water and any dechlorinator will be fine, including the original one you had (Blue Planet).
Just do a 75% water change each day using dechlorinated water until there is no more ammonia or nitrite readings. As long as the water is free of chlorine you can do a water change each day without any issues.
Water changes will not harm the beneficial filter bacteria as long as the water is free of chlorine/ chloramine.
