I don't think you will see much if any visual difference between those purple bulbs, and the change won't impact the corals in any meaningful way. Raising the light is a start, but be careful to not change too much all at once.
In my experience LPS corals can adapt to a lot of different light conditions even though they are sold as "lower light" corals.
Thanks for the advise...
To be honest i changed yesterday at first the ATI Purple + for the Gissemann Aquapink and the Hammers colors seem less bleach. It's like a more rose color specially on the tips. Also, the Blue tips ACRO and a 3 color Torch are more noticeable with all the bulbs on which use to be pale. After that I also changed ATI True Actinic for the Gissemann for the Pure Actinic and overhere the improvement was not that much as you said.
Today i am going swap 2 Gissemann Actinic + for the Blue + and see how it looks. The final combination will be 1 B+, 1 C+, 2 Actinic +, Aquapink and Pure Actinic so lets see if i get a change and improvement.
