hi, all im looking to start my first saltwater tank and i have a question about all in one tanks. these little acrylic dividers seem to be very valuable and drive the cost of the tank dramatically. im wondering is it worth the money to buy one? im sure their efficiency, customizability, and convenience will be valuable but is it practical to make my own in terms of cost and difficulty? i have been looking at the innovative marine 25 nuvo lagoon i like its larger footprint over height and so im nervous about finding a tank with similar dimensions and making my own "AIO box". thanks to all who answer! like i said im new to this so this will be only the first of many questions to come
