Trying to raise Nitrates

[gregzz4]

I know, it seems kinda weird to most of you, but I want to raise mine some

I'm trying to create a happier environment for my SPS and have read that PO4 and NO3 need to be balanced
Currently I have 0.03 PO4 and undetectable NO3

I've cut my lighting some, from 21 to 17 hours/day total bulb on-time
This has had a good effect, but not enough
I've doubled my fish food; 15 wrasses etc now get 3 large pinches of pellets for lunch and 2 x 1/2" cubes of frozen for dinner. Plus they get flakes and Nori throughout the week - between their feedings when I'm home and remember. This is a HUGE amount of food for the tank, yet I am not seeing any numbers rising

I'm currently considering some more fish. Not only to raise the bio-load, but 'cause we want some other critters

In the meantime, can any of you help me 'raise' my Nitrates so my levels are more balanced, thus making my SPS happier ?

Thanks all
