On occasion, I get the opportunity to update on the tank. This usually involves a break in my clients and also well-timed naps for the kids.
-denitrator working great... nitrates around 5-10ppm... down from 30+ppm. If you see how much I feed a day, it would seem a more impressive feat. Literally zero maintenance on this thing other than making sure the line isn’t clogged and making up some of the alk it eats up.
-phosphate started climbing due to lack of nitrate and associative algal growth. Went to the point where I believe it was leaching back out of the rocks too. I was changing GFO media almost every other day. Setup lanthanum chloride to drop into my skimmer and it’s been able to maintain it around 0.07 ppm right now... down from 0.23 ppm that it got up to at its highest point. Have never run lanthanum on a daily basis before but if I continue to have no issues with running it and it continues to give me good results... may be saying goodbye to GFO
-backup system is rocking with frags and colonies. Keeping colors and showing growth. Enough that I trust it with all new incoming frags now... even my new $700 TSA Bubble Yum half frag.

I may start bringing in some additional imported colonies to try in it. If that goes well, I may add two more tanks to the system and call it a day. So it’ll be four 50-gallon low boy tanks plumbed together. I have the display system and two 50-gallon low boy tanks plumbed together on the other side of the fish room still too.
