What method for reducing nitrates/phosphates do you use?

You mean could I see through the green hair algae, cyano bacteria, and dinoflagellates? You should have seen the sludge in the sand!

225gal display with 100gal sump. I run a fresh cup of GFO each month in a BRS reverse flow reactor for phosphate. My PM Bullet 3 with an Iwaki 70 pump is rated for 400gal by the manufacturer and is perfectly capable at keeping Nitrate undetectable even with heavy feeding. Unfortunately though I do have to run a filter sock (for micro bubbles) on the outflow, it takes up a lot of space, makes a lot of noise and that pump draws a lot of electricity relative to modern pin wheel skimmers with similar ratings.
