What is the most use supplements regardless of price for corals to get more polyps extension, and bigger polyps assume light, water parameters are on point. Thank
Unfortunately their really isn't a good answer for this. Some reefers will say this and others will say that. Putting all supplements aside, I have found that dropping my N03 to below 10 ppm and P04 below .05 has caused them to extend their polyps more in order to catch food.
