[APD] RE: Rift lake refugium- Tom Barr


You helped me out about a year ago as I was setting up a tank in my bosses office for African Cichlids. I set up a 75 gal with a refugium in the stand(20L&10 gal plastic tank in series), 55w PC for lighting, Duckweed, Hygro, and Crypts for plants. I also made two boxes out of Polypropylene and PVC to act as hydroponic cells for Peace Lilies. One is your plastic tube design and the other is a box filled with constantly flooded gravel media with the tank water circulating through it. Twice now the Peace lilies have died in these tanks. The roots rot. I relied on the office room lighting because you said these plants would grow as long as you could read. This still seems correct to me as these plants are found in Malls, Betta bowls and other low light areas. Do you have any comments as to why the plants die?

Thinking the death of the plants was due to insufficient light(in spite of what I just said above), I ordered a 48 inch 4x55w bright kit from AH Supply. It should arrive Thursday. I plan to suspend it above the plant stand from the ceiling. I spoke to our electrician today and he is going to wire me an outlet to plug in the timer. If the Peace lilies die again I plan to purchase a 110 gallon tank to replace the plant stand and plumb it in with the Mbuna tank. The 48 inch Bright kit will then be used for this tank.

I would plant the 110 with Crypts and only use various Tanganykians as I am doing in my home and office.

Err why use submersed plants when good old emergent plants work better,
need less light and are easier to prune?
Simply use hydroponics, place the plants in the sump in Hydroponics media,
(rock wool/clay balls are better though), use ABS or PVC 3" tubes and add a
test cap to the bottom and drill a few small holes in the bottom. Splice
off some of the inflow or use a small powerhead to trickle the sump water
over the media for several of these 3" tubes (pots) and the water flows
over the roots and the filtered water flows out the bottom of the tubes and
back into the sump.

You can make the Tubes 6" 12" 18" etc, whatever range of levels you might
have in your sump.
