Hey all, newbie here. I want to start dosing Red Sea Reef energy AB+ to my Fluval Evo 13.5. I do not have a protein skimmer or internal powerhead but I did upgrade the return pump to a sicce 1.0. The filtration I am using in order is filter floss, carbon bag and marinepure gems. Do I need to turn off the return pump prior to dosing this product or can I leave it on to circulate the water? I don't know if the filter floss or carbon would absorb the reef energy or not.
