Guess the Phosphate level

Wish I could have made it. I'll be in DC next year though...

Thanks Lee. :D

I got some new tests from AWT back today, but they sat for a week and seem insane, so I'll send another set tomorrow.
 
Still tagging along. Using phosban since tank was set up and PO4 still undetectable. Adding more frags today...
 
New test. There was a water change in between too. Last results below:

Algae has been a problem and confusing since before we were able to test for and reduce phosphate. Before phosphate, we had very much the same discussion about nitrate. There are many things that can impact algae growth so it is hard to say what exactly makes the difference. Is it herbivores? Is the nutrient load in the water column different from the load in the substrate? Does the maturity of the tank matter?

Agreed. 20 Years ago it was Nitrates. 10 years ago it was Phosphates. Now we can positively point to both being useful to coral growth. But in all cases, and for many decades, we've always said try to out-compete algae and you'll be fine.

Proper control of bryopsis and dinoflagellates is incredibly easy if you use natural control methods: Live rock, deep sand beds, 1000's of cerith snails, tangs, blennys, algae scrubbers, cryptic zones, etc.

It's fairly easy to create a full blown ecosystem within a box, you just need to make sure that the ecosystem is stable for it's size.

great post. creating a balanced ecosystem is my favorite part o the aquarium hobby.

in a different but equally great note. I totally read your name as epic boner lol ;)
 
I'm old enough to remember when Frued was taught in every class..
I think he has fallen out of scholastic fashion..
This side track is a train wreck waiting to happen..
Thales, quick!! Tell us about your ats!!
