Yes
That was my point, make it as easy as possible for him, less waterchanges that you need to do the better IMO. Lower costs in the end too, basically a 10gal bucket of saltwater would last him 10 weeks at 1 waterchange per week, or if he has a refuge, its 1g change every other week, so that 10gal lasts 10 weeks, or 5 months, and at 30 bucks for a bucket of saltwater, that refuge more than covers its cost
