Yeh maybe you right. I was thinking of couple factors, no more sand, which might mean less ca buffer.
with larger volume, dilution is more and coral access to the supplement is slightly less accessible...I thought that's why supplements specify dosing amount per volume unit, more volume, more dose...no?
And as you also rightfully said more surface area might mean more caroline algae and which sucks in alk further..
But you have a good point...time will tell.
I’ve been bare bottom for a while. No sand in the 250. I’ll never use sand again.
