there is a LFS around my area that uses seawater for their aquarium maintenance services. they claim to purchase the filtered ocean water from catalina water company...I'm really curious if there are any impact when switching from this filtered seawater to RO/DI water or vice versa?

It has been shown to not be especially pure in some tests, and I wouldn't recommend it, but many folks do use it. Here's an analysis:
