Im sorry here is my prognosis.
Your tank is honestly too low tech for the amount of effort your putting in.
Low tech tanks, require a LOT of work, unless you ditch the corals, and lower the light intensity way down.
But Low tech tanks, require constant testing, and also require your dosing to be exact and point on, its very time constrainging, and you said you were 14 right? I just don't think you have that dedication set up yet, especially since you'll be driving age and meeting with girls age soon.
For example, i do not think i could juggle the first time GF/school friends + Low Tech Reef + School Work. And your important high school years are also coming soon.
From what i see, your tank will take MASSIVE amounts of work.
Is this work your able to do, and keep up with constantly?
If i was in your shoes, i could not do this. My High school social life, and that whole experience is something many of us keep longing and looking back to as we got older, and its not something you should have to sacrifice for this hobby.
Again this is my personal suggestion.
When i say low tech, if its not a Nano, where you can do weekly water changes, 7/10 cases i have seen all went down in the gutter.
Every EQ you add to your tank, makes it that much easier to succeed with minimal amounts of effort and work, but again, its very costly, but like all things in life time = money. Want to save time, you need to spend the money.
Since that isn't there, and soon you'll have even more of a shortage, as regrefullly i have to say this, my recommendation is shutting the tank down until after you finished SAT's if you intend to go to uni/college, and enjoy your teenage years, because they will never come back, and most of would probably give up almost everything we had to go back to those years again.
