coral chips can act as bio media and it leaches calcium carbonate which buffers the hardness of the water and consequently your pH. Biohome acts as a bio media too. Both these media increase the efficiency and capacity of the filter, but the end product of the nitrogen cycle, nitrates, aren't easily removed (lots of plants and industrial sized denitrators aside) except for water changes.

Thanks, so I guess the only and faster way is to do more water changes.

Thanks for clarifying, currently doing about 30% twice weekly, thinking want to increase or not.
