Aquarium Advice Apprentice
Hello i'm new to this forum and have been reading around for some time in regards to retrofitting my existing canopy with some new lights. i came across this sight through this forum and it looks promising.. just wondering if it was over kill. i have a DIY CO2 reactor and a 21 gallon tank. i was thinking of putting the dual 36 watt set up from this site: http://ahsupply.com/36-55w.htm. so that would put me to about 3.4 WPG for a freshwater planted tank. Too much ? any experience with these guys ? one more thing.. does anyone recommend anywhere to get a good heat resistant aquarium cover to protect these lights?
