Oh, hey the photos worked...but the explanations didn't.
Top photo shows the small FW
tank in front of the sump. The FW
tank contains a RIO180 pump connected to clear tubing.
The lower photo shows the end of the clear tubing hung over the sump. The end is plugged and you can see the irrigation dripper. When the pump is turned on, I get about 500ml per hour. I control the system with a digital timer that turns the pump on 6 x per day for 42 minutes each time. Using the timer, I can adjust the amount of water top off per day by the minute.
I am having a new FW
holding tank custom build to hold more water. I want to be able to leave for at least 1 week without refilling the FW
tank. I will also put a floating lid on the FW
tank so that it stops evaporating so much!
