IMO, I would stop dosing ammonia, I feel like that's just adding fuel for the algae.2 Month Update-
2 Months in and things are going okay. Fish are all doing great. No issues at all and am waiting for my next shipment from an online vendor. I am sure this is pretty common but they are causing me no issues and seem as happy as can be, if only I could say the same about coral. For about a week after my 1 month update everything looking great. Diatoms had vanished, algae disappeared, and all corals looked happy. Then I found out the reason my tank looked so clean was due to my Phosphate and Nitrate being 0. Saw some Dino’s forming and my corals, especially softies we’re looking pretty rough, so I started dosing ammonia, aminos, and phosphate to bring everything up. I have succeeded in bringing up phosphates and my corals were looking better, but then the GHA has started. Over the last 10 days Algae has taken over everything, and no matter how much I dose I cannot seem to get my nitrate to come off of 0. At this point I am dosing my tank to almost 1.5ppm ammonia daily. I feel like everything I am feeding to the tank is just boosting Algea growth and the corals are now in a low nutrient system and being smothered by excess algea. I have not lost anything yet as I have been doing aggressive manual algae cleanup, but I can tell that some of my SPS have started bleaching. Not sure if I should cut all the dosing and let nutrients bottom long enough to kill the algae, or stay the course and keep manually removing it. I definitely feel like the bulk of this problem can be attributed to the tank being too new, but I still am enjoying having corals more than I would just having an empty tank at this point so I have no regrets. If anyone has advice for how to rid algae while raising nutrients I am definitely interested in hearing it. No plans to add more corals as I just need the frags to grow out, and after my fish order eventually comes in I won’t be making in major changes to the tank.
I've read this a few times on here, you do have nitrates in the tank. It's just that the algae is growing and sucking it all up. I would keep doing what you are doing, manually removing as needed and keeping up with weekly water changes.
