No salt - is coral substrate helpful?

Post by alex12571 »

I have heard a crushed coral substrate is helpful for maintaining ph.

I have 6 figure 8 puffers.

I have not added any salt as of yet - all I am going by is seeing they are white bellied and bright coloured.

would a coral substrate help with a fresh water setup, or is it just when salt has been added?

Better to use aragonite sand.
