I just purchased the compnent 1+2+3+ bundle from BRS. I have dosed 2 part in the past and had success with it. I wanted to switch to aquaforest with a previous tank but AEFW infested before I could start. This new tank has been running for 6 or so months and corals have begun to be added, so I feel it's now time to start dosing. I just have a couple of questions before I get started. I will be dosing using 2 Neptune dos, this will leave one head not being used is there a 4th product that would be beneficial to dose with it? I understand the initial dosing 50ml/27g until parameters are met and then adjusting from there. My tank is 20g, so I should initially dose 37ml of all three components? Is components 1+2+3+ everything I need to get the basic aquafort program going? If not what else should I get before beginning? I have been using Red Sea blue bucket for my water changes and I have a half of a bucket left. Will it be alright if I finish out the bucket before ordering aquaforest reef salt? Any tips or tricks would be greatly appreciated as well. Thank you in advance.
