You’re the man! Thank you for the supportive advice! I am working with lights rn and have a preset from a fellow 13.5 gallon owner at 65% max lighting. I have heard a lot about the GSP taking over which scares me for the amount of maintenance required lol. Would you suggesting letting my lights acclimate over the next 25 days before adding any corals to the tank? I’m assuming during this acclimation I will start to get the ugly phase and want to get that going before adding any corals to the tank to allow for easier removal.In my opinion you should keep things simple and easy for yourself, so far it's looking great.
If you start removing/adding/ adjusting stuff it just over complicates things and takes away the enjoyment of 'creating your aquarium '
If you feel you are over feeding then you can adjust this yourself by adding less food which will help your aquarium chemistry in the long run.
Unfortunately you will go through an ugly stage at some point if not now then later but it will happen.
I'm unsure about having GSP as a back wall feature as it may grow out of control and smother your rocks, filtration systems etc, maybe try it as an island first and see if you can manage growth but entirely your choice as 'its your aquarium '
Your lights will promote algae growth so research best percentage and hours to have turned on as these vary so much, if you have no corals that have photosynthetic needs then you have freedom to adjust
Your aquarium looks great and I'm following
