Seriously guys im thinking bout getting a jbl kit from thegreenmachine, but have rethinking due to all the nightmarish posts, are these things really that bad?? I just think they must be ok if they are being sold in fish shops. yeah the f/e sound a helluva lot worse but these kits you can buy.....how dodgey are they? Should i even bother? Also what else do i need to put in the tank, meaning fertz wise??? Im new to all this would love some help.
