The moon is moving away from the earth, and its orbit is getting bigger, but their mass has not changed.

So if there is a second moon, its orbit can be farther away from the earth.

Then the two moons will have the same influence on each other's orbits as the Earth and Mars.

In this way, when the gravity of the two moons on the sea water is superimposed, the tide will become larger.

The reason why the time of high tide and low tide is different every day is because the moon has greater influence on the tide than the sun.

If the orbit of the second moon is lower than that of the first moon, then the second moon will have a greater influence on the tides than the first moon. And the second moon in low orbit will circle the earth in a shorter time than the first moon. So the interval between tides, that is, the time between two high tides, will be shortened, depending on the orbit of the second moon. When the gravity of the two moons is superimposed, the intensity of the tides will increase.

If the orbit of the second moon is higher than the orbit of the first moon, the interval between two high tides will remain the same, and the strongest intensity of tides will increase, but not every tide, depending on whether the attraction of the two moons to seawater cancels out or overlaps each other.

I don't think the orbits of the two satellites can be very close. If so, they will form a binary star, orbiting the earth with particles, and the two satellites will also orbit each other. In this way, the interval of tides will not change, but the intensity will increase all the time.
