I begin by positioning the grow bed at the desired position.
|Positioning the grow bed|
|A 25 mm hole drilled at the center|
|Fixed a bulk head fitting together with the strainer holder|
|Strainer pipe held securely by the strainer holder|
|The gap in between the strainer pipe and the tank floor is narrow enough to not let any pebbles through.|
|I used water as a guide to help me level the pebbles.|
I learned a convenient way to wash them from the Backyard Aquaponics forum. Just fill the bag with water until full. Shake it. Then poke some holes to drain the water out.
|Make a hole at one corner and insert a hose into the bag. Start filling it with water.|
|Poke several small holes at the bottom to release the dirty water.|
Aaah~~! A new grow bed filled with fresh growing media!
|Virgin Grow Bed!|
|A new location for my guppy tank.|
|Guppies now enjoy clean water directly from the grow bed. Excess water is drained back into the tilapia tank.|
|A Tee-connector divides the water flow in to both beds.|
