General comment:

The manuscript proposal and experimental design are good. This is an interesting study to evaluate the response of tropical benthic diatoms to high irradiance and temperature based on chl a and photosynthetic parameter analysis. Therefore, this manuscript is recommended for publication. However, there are minor correction need to be done. Please refer to the comments given below:

Abstract

The abstract was good, but what is the unit for recovery rates?

“The recovery rates for samples exposed to temperatures of 40°C  were 4.01E-03 ± 0.002 (kindly put the unit here, If any) and decreased to 1.01E-05 ± 0.001 (kindly put the unit here, if any) at 60°C

Response: The unit for recovery rates is s^-1. See Line 24

Conclusions

Conclusions are good.

References

References are good.

However if possible kindly update the citation/references and it should be the most current within 5 years

Response: Latest citation (within 5 years) has been added. However, most of the past references were maintained as they provide valuable information to this research.

Figure

For Figure 2 (a, b, d), kindly put the x-axis title or you can put the x-axis title at the last graph (Fig.2d) only

Response: x-axis title, which is temperature inserted.
