My tank is a little over a year old now. I made the mistake of carbon dosing way too much and bottomed out my nitrates and phos for months. All my corals were faded and/or dying. Then I got dinos. I figured out the problem and stopped carbon dosing. I don't have a large fish load, so I was having to dose nitrates and phosphates. Dinos have been gone for months now thanks to adding nutrients and a UV temporarily.
Tank was looking great for a while and the corals have really bounced back, but I'm still having a terrible issue with my phosphates. My nitrates are very stable at about 3 ppm. My phosphates are always at 0 ppb per hanna checker. For a while they seemed to be stable, but they never stay up despite dumping in the equivalent of 0.02 ppm of phosphate everyday. I know the hanna is reading correctly.
I think the problem is all the excess algae I now have. I have very small spot of red cyano, which isn't too concerning, but most of my sand is covered in something brown (looks like diatoms but I don't know where the silicate would be coming from. 90% sure it's not dinos again. looks different) and my glass is ALWAYS green. I will clean it and it will literally be entirely green again in 2 hours. There's no algae on rocks except coralline . I think that's where my phosphate is going, but I'm afraid to stop dosing it and have my corals go down death's lane again. Suggestions? Should I just stop dosing and see what happens?
Sorry for the novel. Thanks
