I have a grand trine in water.
Besides the what is listed on https://satanisgod.org/www.angelfire.com/empire/serpentis666/CONFIGURATIONS.html
Does the grand trine have any effects on the planets/houses involved or is it just like normal trine effects?

If it matters the placements are

Jupiter Scorpio 2nd House

SaturnR Pisces 6th House

Mars Cancer 10th House

Thank you for any help

Do not reveal your personal information. This is dangerous.

No, it does not have a "direct" effect on houses or planets, because it is related more to issues of emphasizing an element in the arrangement of one's Soul.

.

It does mean the energies of these planets will flow between one another more harmoniously and easily which can also indicate a knack for certain talents that might come easy. In this case, it is the affairs having to do with the water element which is reading subtle nuances, intuition and spirituality. It can make the element show quite prominently unless other placements overcrowd it.
