The ear plug should have a small hole or a tube inside it so you can still equalize with it.
About the pro plugs: They only help little with equalizing and are mostly meant for keeping water rushing into the ear to a minimum.
Water in ears is no problem for equalization.
Edit: Wild guess: Do you maybe start equalizing to late? At 7 feet can be already to late for some people, also some people tend to try to harder if it doesn't work.. Which makes it worse and can result in damage.
When diving straight down,
immediately start to equalize, if it doesn't work directly: stop or abort your descent. It only gets harder with more depth, you need the early equalize to be able to equalize at depth.
I've been using ProPugs for 25 years. IMO they do nothing for equalization. They help immensely for keeping water out of the ear if sized and inserted properly.
7' is WAY WAY WAY too late. 6' is too late. 4' is too late. Anything below 2' to start is pushing the envelope, especially if you have trouble with clearing.
Start at the surface, then every 2'.
There is a technique where you pressurize your ears, then dive and continue to pressurize them on the entire descent. You POP your ears (clear), then gently hold them open as you dive.
First, you absolutely need to figure out how to clear your ears, in total control, in a non-performance situation. If you can't do that, I seriously doubt you can do your task.
