As long as the sump was drained and moved, I emptied clothes out of a matching tote and set up a pair of sumps to increase the water volume of this system by 33% or so.
The water bridge is a simple siphon tube that keeps the water level the same between the two totes I am using for a sump. There is a pump in the right tote and water drains into both of them about evenly.
The siphon water bridge. I oversize all non-powered water lines so that they can keep up with those under power – pumps can move a lot of water in small lines. Gravity is much more leisurely.
There are now 3 siphons in this aquaponics setup. Water flows from the sumps up to the grow bed on top of the aquarium where a bell siphon drains the grow bed to the aquarium. The aquarium has a siphon to a overflow box that drains to a wicking grow bed. Then there is the leveling siphon between the two sumps.
Clockwise from top left: Aloe, ficus, jade, some weird zig-zag plant, spider plant, geranium, spider fern, some hen&chicks or similar, and two barely hanging on African violets.
