well so far so good on the eco complete. i am using metal halides on my tank btu only because i had them. Right now I have 2 x 250 watts 10k on there . I had 14k and have recently switched. so far so good. I have had growth already and the tank has been set up about a month. i just added a CO2 set up today so I am hoping for positive results with that lighting. I like the T5 lights and contemplated selling my MH's but decided since i had them to go ahead and try them. FW is new to me and even more so a planted FW tank so I am on a huge learning curve.
but never the less i am having fun!!
