Im a 5 gallon buckets guy. I was raising 50 fry per 100g stock tank this spring...cleaned um all using a 5g bucket. Thats lots of trips with a 5g bucket. 
Looks like you could grow macros in that little basket, and yes, I always recommend purigen. I cleaned a tank of a buddies that hasnt gotten an h2o change probably in MONTHS...only reason the corals are thriving and the fish are doing fine is because he forgot that he had purigen in the back of his HOB...what a hobo.
