I thank all of you for you help.
This change won't happens instantly, for the first year, my tank PH was at 7.8, stable, day and night. Now it seems to be more at 8 in the morning, 8.2 in the evening.

Just make sure you keep a stable Alk near 8-9 dKH°. Don't dose drastically chems to match perfect range. If your KH is in good range, then no worries for the PH, the corals will stay healty and will keep growing normally if you don' play with the params. Raising the PH (with kalk for example) will boost it for a day, then it'll drop.

I already dosed kalk to keep a 8.5 PH (Was trying to kill dinoflagellates invasion with high PH), but was impossible to keep it high. Even if the KH was at 8.5 dKH°, after 12-24h, the PH was back to 7.8-7.9. THe corals weren't happy, because I was messing a lot with the PH.

Don't play with it, I would worry if you reach an unstable <7.6.

Depends on your corals needs, but I would say yes... If everything is ok (no cyanobacterias), I think you can keep it like this. More powerheads = more flow patterns possibility.
