Hey everyone so I'm pretty sure I'm having a dino outbreak. Tank is 25 gal and been setup for a few months but with some existing live sand and rock from my previous tank. Tank is an AIO so I just have basic filtration in the back and was running chemi pure elite. I then switched to chemi pure blue because my phosphates were a little higher than desired. However, this dropped my phosphates to 0.00 for about a day. Right now they are ranging from 0.05-0.10. Nitrates have stayed at about 10. I believe that zeroing out my phosphates caused the outbreak and I therefore believe that I have autotrophic dinoflagellates. I attached pictures fo you to see because maybe I am wrong.
My game plan is to blackout the tank and run my ai prime blue at 5% for about 4 days. Will this hurt my corals? I have some beginner sps like stylophora and don't want to cause them any damage. I also plan on dosing microbacter 7 daily and frequently changing out filter floss. I will continue to feed my 3 fish as normal. I turned off all flow except for the main return pump. This is what my research has told me to do. Is any of this wrong, or is there anything else I should be doing? I don't have much sand in the tank as it is but would it be smart to suck all the sand with dinos out of the tank? I would greatly appreciate any advice.
