What is a Sump Ready Frag aquarium?

A Sump Ready frag aquarium is also known as an overflow aquarium. Overflow frag aquariums have an overflow box built into the tank that allows water to overflow into a sump or other filtration system. This allows for a more efficient and effective filtration system, as well as a more stable water level in the main tank.

What are the key differences between a Sump Ready frag aquarium and AIO?

Overflow frag aquariums often have a larger water volume compared to AIO frag aquariums, which leads to more stable water chemistry and conditions.

Overflow frag aquarium also can accommodate more equipment, such as a chiller, protein skimmer, and dosing pumps which is beneficial for maintaining good water quality and parameters.

Which is the better choice for me?

Overall, the choice between an overflow frag aquarium and an AIO frag aquarium will depend on your own personal preferences and the specific needs of your coral frags. Both types can be suitable for growing healthy coral frags, but overflow frag aquariums offer more flexibility and performance, while AIO frag aquariums offer more convenience and simplicity.
