Overfeeding problem

[yahoo.roar]

Hi there,

How to find out if i'm overfeeding to my tank, if no3 and po4 doesn't rise...is that means its not overfeeding?

I have build my coral tank with AF system for 6 months, however my sps are unhealthy...there are some of them burnt tips, but i didn't put any elements supplement, just coral food like AVBE, pure food, power food and phyto mix.

Besides burnt tips, they are also stop stretching their polyps.

Please give me some advice, thanks

What are your export methods? You can decrease export or continue to increase import/feeding.
And what do you mean by over feeding? How do you know you’re over feeding?

I'm using AF phosphate minus, and change 20% water every week...also use pro bio s and -np pro

thats my question...cause there isn't too much coral left in my tank now, but i'm still keep using pure food, power food and phyto mix everyday...ABVE every other day

maybe stop changing water so much and take Phos minus offline for now.
