Started setting up the old filter.
Thinking of doing 3 filters along the narrow wall instead of moving them to the left in spring. And on the left, doing a stepped waterfall of sorts to deal with and hide all the awkwardness over there. Maybe put the bog on the front left corner, too. To further deal with the odd dirt.
Ordered some uniseals to test. Still need to find another red bin, but none in stock the other day. Also ordered bioballs to put into each end filter bin.
