Initially I had a nitrate/phosphate issue where nitrates were at 30 and phosphates were at 1.5.
changed feeding (including feeder, food types) and nopox and got the nitrates down to 10-12. Fine with with that. Phosphate still was hanging at 1.1 and just not coming down. Added HC GFO to a media bag and stowed underneath a high flow area.
Now that it hit .8-.9 (and below) I see a huge area of algae (cyano?) on the front glass that blots out everything -it’s red and stringy when I clear it but the tang eats it off the glass-so cyano or something else?
Either way I wonder if this caused by an imbalance of n : p or something entirely else. I have taken out the gfo for now.
Right nitrate at 9.8 and phosphate at 7.3-both Red Sea and tropic Marin’s n : p solutions tout a 10:1 ratio so even if use either one it will mean that I still have 1 ppm phosphate (at 10 which seems to be prohibiting growth in the sps. The lps seem fine with it. Any input /recommendations appreciated.
