Oceanbox Designs™ AIO Kit provides highly efficient internal filtration by forcing water through specifically designed modular media racks and baffles system. The multi-stage modular media racks allow you to run different filter media such as filter pad, carbon, purigen, phosguard, ect keeping your tank clean and your salty critters happy. A huge advantage of having an AIO system is the ability to run and hide essential equipment from view such as heater, auto-top-off sensor, temperature probe, and even a small skimmer or reactor if space is allowed.
