Hello guys! This is my first post here. My tank is a couple years old, 300 Litre/80 gallon with a sump. I've lost some control the past year due to university and work, but now I am wanting to get back on top of it all. I lost most of my corals over the course of the year, but I still have 2 very happy bubble colonies and a lot of mushrooms (which are splitting and growing at an alarming rate lol). I've sadly lost my Euphyllias, which I most want to be able to keep. My parameters are as follows:
Salinity: 1.026
Temperature: 26Celsius/78.8Farenheit
pH: 7.7 (salifert was about 7.5 but I have trouble reading it. API was about 7.9) (also this was tested in the evening)
Alkalinity: 14dKH
Calcium: 460ppm
Phosphate: 1.0+ (the nyos chart didn't go high enough) (I'm probably overfeeding, trying to get my mandarin fat)
Nitrate: 35ppm
As you can see, most things are a bit off, with phosphate seeming pretty scary! Despite that, the 2 coral species I do have are positively thriving. I am wondering what I should try and tackle first. Before I tested, I was expecting to need alk and calcium supplements, but it seems after a generous water change they're even higher than I need. I'm not even having much algae growth, I only scrape the glass once a week at most to keep it crystal clear.
Should I just do more regular water changes to balance things out? Is there a particular parameter that would be fine for bubbles/mushrooms, but toxic to Euphyllias/gonis? Or is it more likely a combo of everything, adding up to a big problem?
