Hello I am upgrading my current saltwater mixed reef tank to a larger aquarium. The new tank is 170 total gallon setup, 130 display and 40 gallon sump. I want this to be an Aquaforest tank! I about to purchase Bio S, -NP Bio S and Pro Bio S to start my bio load. So here is my question, Which size bottle will work for my tank? Will the 10ml bottle be enough to dose 6-7 drops for 2 weeks? Or do I need to purchase the 25ml bottles?
Thank you!
Thank you!
