IOS or EOS

[RushAct]

Hello bros, anyone can point out the pros and cons for both overflow system?

Thank you very much

The only difference is EOS does not take up valuable space of your tank .

That is only What I can think off.

What i like on eos more space and easy for rockscape,more water movement around the tank.

EOS has more oxygen exchange compare to IOS and IOS seems more difficult to maintain.

IOS runs much deeper than EOS and it tends to settle detritus in the long run, but it just takes up part of your main tank space.

EOS sticks out like a sore thumb, but if you have additional cabinet space to mask it away it is fine. Alternatively have it behind the tank, but you will also need to move the tank further out. Additional space is the key.

thanks for the replies, guess there is no reason to get a IOS.
