Will there be enough O2

Hi

Rena Aqualife 200 x 50
Dimensions: 201cm W x 51cm x D 70,5 cm H
80 x 20 x 27
Volume in litres: 717
Tank Volume in imperial gallons: 157
Water Volume in imperial gallons: 146

Filtration
FLUVAL FX5 Canister Filter x 2

Co2 via an external diffuser into the outflow of the FX5.

Will I need to get extra 02 via air stone or agitating the surface somehow or will the plants produce enough during the day ?, what happens at night ?

Thanks in advance

In a highlight tank the plants should produce enough O2. Pearling is the plants producing so much o2 the water is saturated with it! My main tank runs the drop checker in the yellow green range and there is almost no surface water movement. I never see the fish gasping, and Ive got cory's.

Ditto to what Sam said. I would be much more concerned about the "Do I have enough CO2" question. More CO2 will yield more O2 during the photoperiod (assuming you have good plant mass) providing enough saturation to last the night.

Cheers,
