i have a 150g. tank. the dimensions are as follows....5' x 2' x 2'. inhabitants: mixed pygos, and various plant life. i dont have a lighting system that can accomidate this amount of "stuff". to top it off i am strapped for cash. my question....what kinda of lighting system should i get and from where? every lfs in town is asking like $200-$300. i cant afford that. i have also checked out ebay and the lighting systems there sell for about that too. i think buying used is the best bet. but not a lot of people are selling lighting equipment and when they do it's not enough. i would really appreciated a little help. thank you in advance.
