Wow, Researching for beamswork i stumbled upon this thread and i am amazed and shocked(at aquatraders). i was shopping around and was thinking about buying a beamswork fixture for my 40 gallon breeder. its 36 inches and its planted. So i was assuming Double bright 2600k. do you know if this is enough? Also i was thinking about switching out my POS(excuse my language) 48 inch t8 shop light for my 125 gallon. Any suggestion? I do got some plants in the 125 gallon tank too. but they are low light plants.. they'll grow in anything. Suggestions plz! I love mfk. every time i have a problem and i need to research, I google, and it always ends up back to MFK!. MFK PRIDE!
