I’d be careful going this route with mariculture pieces. Chasing numbers is not what you want to do with Acropora, especially ocean grown. Keep it simple. Your numbers all look good you just need a more established and plentiful bio load. One year is not much for a reef tanks maturity to set in. Feed your fish multiple times a day until they are full, and find a way to get some more LR either from an older system or from the ocean. As long as you’re keeping KH in the mid 7s and have that natural sunlight the corals have a good chance at holding on even with low No3. Just keep up with the feeding
