The tides are also affected by the Sun's position too, however the Sun's affect on the tides is only around 1/2 of the moon's force. Therefore during a solar eclipse the tides would be amplified at opposite ends they cancel each other.
The best example of tides is Jupiter's planet Io. Before Voyager 2 even too photographs of it, the surface was predicted to have lava on it because of how close it is to Jupiter, its almost within its Roche limit which means the force would shred the planet and it would be part of Jupiter's rings. And it does indeed look like a pizza from the extreme tidal forces.
If Earth's moon had water on it, the tidal forces the Earth to the moon would have a constant violent storm.
One hypothesis is if all the Jovian planets lined up it would affect Earth's tides so much that Earth would shred. However not even Jupiter itself has an impact on Earth's tide. It would take like 50 Jupiters lined up to have a tidal effect.
