I need to add some live sand to my 14 gal. tank and am not sure if/how to do this. I started with about an inch or so deep. However, recently, I am having had to scoop sand out along with the red algae (cyanobacteria) that has infested the tank. Now the sand is low and I'm sure the good bacteria need help. I continue the quest for the ideal combo of rock, critters, food, etc. over the past 9 months and am slowly getting there. Nothing has died for the past month. But the red cyano stuff is persistent and I continue to cut back on lighting and food. If I do add some additional live sand, how should I go about it? Any advice is welcome.
try reducing feeding light and check the phosphate level,.......adding sand without solving the cyano prob is not the solution, I would take a cup of sand fill it with fresh water lower it to the bed and dump it. sorry just saw you have reduced light, ever tried phosban?
