We ran our system for 5 years before the snail invasion .
The fish did not seem to eat many of the snails.
This week we shut down
the vegetable troughs and kept the fish on standby.
We emptied the water from the vegetable troughs , cleaned out the sludge at the bottom , bleached the troughs,
washed the rafts , let everything sun dry , washed out again and refilled with clean water.
We let the water sit for two days to burn off any chlorine before hooking everything up to the fish tanks.
Pumps are on and water is flowing .
Today we plant new sets.
To prevent a new invasion of snails , slugs etc we bought 50 pounds of diatomaceous
earth and spread it on the ground around the plant troughs.
Hopefully we are good to go for another 5 years.
