Personally I would remove the activated carbon anyway as its not needed on a daily occurance in your filter and is normally only effective for a few days. Carbons main purpose is to remove colour tannins and medications from the water but after 2-3 days it becomes ineffective. I think you would benefit more from having an extra course sponge in your filter instead for bacteria to grow on, preferably a mature sponge if you can find a donator.
I think you are prob still right at the start of your cycle and as already mentioned, the fish you have are low waste producers so the cycle is prob slow starting. I'd recommend rehoming the panda's as they are sensitive fish and doing a fishless cycle with ammonia, but its up to you. If you decide to keep the fish and carry on with a fish-in cycle then you will need to do daily water changes, and 20% won't be any good. You need to be changing 50% at a time.
