How do YOU lower your Nitrates and Phosphates?

[reefwars]

mostly water changes for nitrates iVe went down from 20 to 5 but ive had to replace old rock and cut my feeding down alot. it would seem im stuck ay 5 though so im considering other options so ill be following along here closely

for my new set up after christmas im going to be using a phosban reactor and keeping a better eye on things right from the start.

my old 180 i bought second hand off another reefer , nitrates were off the chart ,literally ,lol we took it on as a project and got them down to 40 with massive water changes and reduced light to kill the hair algae. id say about 80% of the tank was completely engulfed in hair algae and not the odd patch i mean completely covered in long algae.all ther corals were dead and covered in algae all the glass was covered and only but a couple of fish were saveable ahhh goodtimes learned alot from that set up
