How do I dissolve precipitate?

A couple hours in 100% vinegar did the trick, thanks.

Great!!!!!!!!!

Most people don't use sponges to "protect the return pump" in their standard setups. Is there something in particular with the Red Sea system that requires the pump to have protection? I see the sponge as a great place for detritus and other junk to collect and possibly contribute to a nitrate issue for your tank. Do you really need to sponge?

There aren't sponges in bubble traps just before the return section? I have one and it came with my Trigger system sump

OP has the old Red Sea 250.

Red Sea used the sponges for mechanical filtration and bubble traps.

Dual Purpose.

It's handy to keep powdered Citric Acid around to dissolve tough carbonate buildup. I use it for soaking tank side power heads.
