I'm having the worst time keeping my acros happy. I'll get several months of great color/growth, then several more of stn and algae issues. Then the cycle starts again.
Right now, my acros are in the stn phase and I have green turf algae taking over, literally. Maybe the turf algae is taking up all the nutrients and starving the acros? I have several fish and feed them heavily every day that I'm home. Also feed the tank reef chili or reef roids daily when home.
I'm getting ready to dose Vibrant to help get rid of the turf algae but fear that may only worsen the stn issue.
Here's some numbers:
90g tank
2x250w MH
4x54 t5
2 mp 40's
Sg 1.025
Alk 7.3-7.7
Ca 480
No3 trace
Po4 0
Mg 1470
Ph 7.9-8.4
I have my 2 part on a doser that drips every hour 24/7 to help control swings, but I still got 'em. My ph starts at 7.9 or 8.0 in the morning before the lights and ends at 8.4 at the end of the day. 6 hours on halides and 8 hours with t5's.
I cannot get my N/P to raise, regardless of how I feed. I don't know how to explain the alk swings from week to week. One week closer to 7 and 8 the next.
I have had my skimmer turned off for several months and have not done a water change in 3 months or so. UV sterilizer is still running.
I am open to hear what everybody has to say. I really need some help.
I use to have an amazing sps tank but can't figure this out.
Thanks,
Charlie
