Are you familiar with the Redfield Ratio?
I'm waiting on your explaination.
I don't understand the question. If the sand bed takes out a lot of nitrogen, leaving phosphorus, and I use iron oxide to bind the phosphate, I can keep phospahte and nitrogen low.

Yes you can. You can keep it
low for the most part. Unless your algae goes sexual, you don't clean it in time, any one of a dozen different things do or don't happen.
The animals you're able to keep will be dictated by that "low" level or their tolerance to a screw up.
What has to be taking place in a closed system for you to have a "low" level?

Your sink is full, it's not performing denitrification properly, you're layers a screwed up and you have a low level of P.
