Quinn,
I do an Instant Ocean bucket ( I think it's 7 gallons? ) water change every week. I have a 120g tank, 30g sump, 20g fuge. I think it's better for smaller more frequent water changes.
I'll try and get you pics. I've got a valve off one of my drain's that I use to remove water from the system. And I've got another Instant Ocean bucket raised above the sump. This is my "mixing bucket" I have it plumbed so that I just add water, salt, heat, and mix it then turn a valve to open it so it drains to the sump. Takes about 3 minutes to do a water change.
I just wish I had a drain in my room. I've to haul the other IO bucket to the bathtub. Lifes rough.
