Oh wow, I'd just use a refugium and run a phosban reactor with carbon in it and call it a day then.
leave the refugium in place, add this to the refugium or even the main tank.

I use just a refugium. Works great for me. OF course it's also an enttire 10 gallon tank dedicated to a refugium.
Exactly mine would have to be so small it would do nothing.
