DIY Lighting for Canopy

[fishnut]

Thanks to all who responded - I found this info very helpful. Going to test for phosphates and nitrates when I get test kits. I did notice a dead area in the tank in front of the overflow - the red algae is growing thicker here - will set up PH to increase water flow. Glad I didn't go ahead and use "quick-fix" antibiotic before getting opinions from this board - tks.
