I cycled a freshwater 180g african Cichlid aquarium a few weeks ago. I put a L4 on it right away. I started running it with only 7 hours a day to get it started. This was not working and when I jump it up to 10 hours a day it kicked in. I'm finding that as I up the hours it is growing more and more. I also added my L2 to it a week ago and have it running on the same timer at 10 hours a day. It is half covered with green already. I'm thinking to up the Led timer to 14 hours. So far it is not keeping up with the Nitrates. I did a water change thursday and the Nitrates went from 30 down to 20. Now today 2 days latter they are back to 30. So at this point I'm doing 3x40 gallon water changes on the 180g a week. I'm hoping to keep the Nitrates down at 5-20ppm. Here is the L4 screen at today's cleaning. Thinking to clean the L2 mid week to spit them up. Thoughts?
