Tank looking crummy please help!

[A.G]

how long has this been going on
2 weeks?
less.
just about enough time for the bio pellets to start working since you've been using them for a month.
most biopellets say that you should stop using your gfo for a bit because that absorbs the phosphates. if you're still running gfo the biopellets could have nothing to consume and start consuming good nutrients starving your corals?

just an idea

also your low ph might be a result from the biopellets reducing oxygen.

+1 I had the same thing happned when I had the pelletes . Give it a try and remove them for now , do a water change and let the tank for a couple of weeks.
