Hi to all bro's & sis's reefers,
i'm new to this hobby, my question here is my existing 3' x 1.5' x 21"h only has a
barely 2" sand bed thickness, from what I understand, having a DSB will have a
advantage of reducing no3, is it true?
If it is true can i simply add more sand bed on my display tank, maybe total thickness up to 4" to 5".
I'm now keeping 5 small fish, 2 bubbles & couple of mushroom & my tank is now about 9 months old.
Need some advice from senior reefers here, really appriciate and thanks in advance.
