Hello,
During your cycle I would not add anything. I think that if you start adding the products too early, you will aid and encourage an
algae bloom. The best thing that you can do for your tank is to take your time, post questions, read and research.
The jury is out weather some of the items you mentions actually do anything other than drain your wallet. I would only add what you can test for and maybe some Stromium and Moly but that is up to you. In a reef tank I add:
1.) Calcium when needed.
2.) Alk buffer when needed.
3.) Iodine for the polyps when needed.
4.) Stromium and Moly (Sparingly)
When I was new I started added the stromium and moly additive too early and it ended up encouraging a bad algae bloom that turned into a mess. Depending on how big your tank is, you might not have add anything at all and just let the water changes keep supplying what you need. For now, just sit and watch you tank cycle and use only RO or DI water.
