Thanks! Your site has a ton of information! And that bubble tipped
anemone is huuuuge.

This may seem like a silly question, but are all hyrometers the same or
are the aquarium/salinity ones different? I have a triple mass
hydrometer I use for brewing, is this the same thing?

It sounds like sal****er doesn't need the massive weekly water changes
that freshwater does, is that correct? That changes where I can place
my tank. My 30/40 gallon freshwater (its a strange shape so i dont know
the actual gallonage) takes 30% water changes a week... I would die if
I had to do that with buckets.
