Hi,

Can you correct the following phrase?

You can only dive at low tides, this implies a reservation of at least one day before, and at the same time, our staff will inform you about the time of the tides.

I would use "... one day in advance ..."
"The time of the tides" is fine. You can also say "the tide times".
