I have found that regarding reefkeeping, the online consensus for everything is to be way more careful and restrictive, than actually necessary. I've had people in another reef forum telling me all along that I was moving too quickly, doing this wrong, wait 6 months for that, I need an ATO, need more light, etc. I mostly ignored it all and have had success so far. Even with transferring everything in the tank to larger setups twice now within a year (newest setup is also a peninsula btw)
Id say go with your gut, looks like your doing great. This tank is going to be awesome.
