Love your tank & I too run a top sump with a MJ900 feeding it.
Ya know you could get a 40g breeder tank, which go on sale at Petco & Petsmart on the $1/1G sale every now & again. Then you get one of those clamp on sock holders & run a filter sock into a container that you can pickup at a $1 store or Walmart. One of those storage containers, but just make sure it is food grade or has the recycle number "5" on the container & I think "3" can be used as well.
