Ok that movie 'What the Bleep do we know' is also a book - found it at Barnes and Nobles (24.99) I believe. As for the Moon Magick - heres what I know..

Waning Moon - banishing negativity - because the Moon is leaving, the lore is that when we do this type of magick now, the negativity wil flow away with the moon.

New Moon - beginnings - the same applies here - new moon is equal to bringing in positivity

Full Moon - highest time for magick - and yes this does have to do with the tides and water - a person, if you notice, is a little 'odd' during this time of the month, this is due to the 'power' the moon has over our physical bodies, the water in other words. Take a look at animals, insects etc, they all act a little odd also. Magick and the Moon is strong due to our lunar pulls - our bodies pull to the lunar closeness to the earth.

Waxing - love, wealth, etc - again, the lunar pull and closing, coming in etc

Dark Moon - some say this is the time of month to do nothing, others say go ahead - I say it is the time to relax as the body needs to refuel itself at this time.

The actual "essence" of the power used in Moon Magic, originates out among the stars. The Sun draws in the stellar influences and transmits them into our Solar System. The Planets within our System absorb this energy which then merges with their own vibrations or energies. The Planets, in turn, then emanate a composite energy within our Solar System. Each Planet's energy or vibratory pattern is unique, and influences other planetary bodies and forces, within each planet's sphere of influence. This is the basis of Astrology and Planetary correspondences in Magic (this is how and why it works).
The Moon is the focal point of power upon the Earth. The Moon absorbs, condenses, and channels all of these forces, which are then carried to our Planet, upon the Lunar Light Spectrum. Without the Moon we cannot make use of the Universal Forces beyond her. In Moon Magic, the ritual altar is the focal point for the Lunar forces which are drawn upon. Women are the vessels for Lunar Energy, receiving and directing the magical force. Men can also become lunar vessels, but women are much better suited (as their biology is more attuned to the Moon's Cycles, than are men's biology).
Agrippa, a 15th Century magician, understood these principles when he wrote

"...but the Moon, the nearest to the heavenly influences,
by the swiftness of her course,
is joined to the sun,
and the other planets and stars,
as a conception,
bringing them forth to the inferior world,
as being next to itself,
for all the stars have influence on it,
being the last receiver,
which afterwards communicates the influence of all superiors to these inferiors,
and pours them forth upon the Earth..."

I hope this is helpful
