So here’s the story, about a month n half ago I upgraded to a lagoon 25 from a nuvo 10. The nuvo 10 was up and running for a year before the upgrade. Transfered all live rock, filter media ( matrix), inverts , fish and corals plus 80% of the old tank water to the 25 lagoon. Everything looked good for about 2 weeks besides a lil Cyano and then one day I noticed the water was cloudy and most of the corals looked irritated and closed up. Figured it was a bacterial bloom so I ordered some microbacter 7 and started dosing following the instructions, about a week into dosing microbacter a lot of my corals browned out and po4 dropped to 0. A month later tank water is still cloudy and Cyano is out of control and I can’t get any detectable po4 on my Hanna checker.
5 days ago I started dosing neophos to try to bring up po4 been dosing .01 daily for 5 days and still getting a 0 po4 reading ,corals are not doing well and water is still cloudy. Not really sure what to do from here.

Micro bacter7 kills your phosphate I'm pretty sure., i dosed it once when i was cycling my tank that had I wanted to try to add some more bacteria as I figured it couldn't hurt and i wanted to boost the bio filtraish there was some algae growth i was ok with.. dosed microbacter 7 one day, and it cleared the algae and tanked my po4 to 0. wich wasnt ideal. my beginner mistake it set me back for a while.Not sure why you would counter a bacterial bloom with more bacteria but what is your concern now? The pictures don't look crazy imo (as far as cloudy water). You can change 100% of the water if necessary. Carbon should/could help. Wet skimming will remove more dirty water. What have you tried so far to clear it up?
