I have a 125g with 13 fish i know that size matters but 13 fish and I can not get any phosphates or nitrates . They are at undetectable levels. I turn the lights off on my algea turf scubber for 3 days and made it to .03 phosphates. And my tank has stopped using alkalinity . I was dosing everyday now it just stays at 8.5 not that I'm upset about it . If I leave the light off on my ats the algea will die. It took so long to get it working now it works to good. Do I just feed more. I am at 3 cubes and 3 pinches of flake and a cube of freeze dried brine. 1 4 inch yt. 1 , 5 inch fox face 7 green chromis 1 neon goby 1 flame angle 2 ,3 inch clarkii clowns I feel like I am over stocked . 110 pounds of rock . Any suggestions!!!
