I've been having high calcium level ~600mg and has not been successful in bringing it down. I understand that the optimum level is 420mg. Will high calcium affects my corals or fishes?
I've DSB of about 3.5inch. However, my tomato clown and the blue damsels keep pushing the sand towards the front leaving the centre shallower to ~2inches. Is it necessary and safe to add in additional sand? I heard DSB is good at controlling nitrate level. How long will it come into effect?
