a friend of mine has a aquatic life unit on his 125 , put out good light but agian the bluls are not the greatest also he is unable to change the programing on the comtroler that is built in,,,,, ill say to you what i said to him you get what you pay for the 2 most expensive things you are going to spend on setting up a system is your skimmer and lighting, if you go cheap you may not be happy with what you get , spend the extra money up front and you will not end up turning around later and spending it all over agian . my self i learned the hard way ,
