Reef Pilot's Undersea Oasis

[Reef Pilot]

I mentioned at the beginning that I had really high nitrates (up to 100ppm) in my 10+ year old tank. After reading on Canreef and elsewhere about refugiums and macro algae, I decided to give that a try. As you can see, caulerpa and chaeto thrived in there.


But it didn't make a dent with my nitrates. I also did big water changes, and the nitrates would drop a bit then, but be right back up there in a few days. Seems that I just couldn't get them to stay below 40 ppm for any length of time.
