I first tested P04 a little over a year ago with an elos test kit. The reading was .75 and presently it is .01

In the past 14 months this is what I've done:
Doubled my water changes and currently do +/-27gal weekly on a 270gal system.
Started running 250ml rowaphos which I change monthly.
I grow both chaetomorphia and gracillaria in a fuge, formerly I only grew one or the other.
Strain all of my frozen food of its packing fluids.
I've increased the flow in my display to about 30x/hr turnover from 20x.
Upgraded my skimmer from a PM Bullet 2 to a 3.
Decreased the bioload on my tank by unintentionally losing my big lionfish.
Removed my remote DSB (PO4 binds to calcium carbonate).
Built a larger DIY Kalk Reactor (its suppose to precipitate PO4 from solution so that it can be skimmed out).
