akashi Posted October 11, 2016 Share Posted October 11, 2016 Have a 29 biocube with a nice stock of coral so far and 1 fish, lately have been battling cyano, tank is approximately 5-6 months and these past 1 1/2 months I've been battling cyano week to week. For my filtration I'm running filter floss, carbon and just started phosgaurd 3 days ago. Cyano is still growing on the sandbed. I also try to do 2-3 water changes a week Current lights I have are rapidled diy biocube 29 led full spectrum: 1 Red, 1 Green, 4 UV, 8 Cool White, 10 Royal Blue (UV/Red must be run at 0.7A max). Running 2 channels with these lights and I have them turn on at 3pm-11:59 now they turn off at 8pm I also had channel 1 mostly whites and few blues red and green intensity at 160 and channel 2 mostly blue with a few whites on at 120, recently I've turned them down by 20 each. Tank is currently on black out its 3rd day. Link to comment
Clown79 Posted October 11, 2016 Share Posted October 11, 2016 What is your nitrate and phos levels? Do you vacuum your sandbed? How often is floss changed? Whats the flow in the tank? Link to comment
