I have two fish tanks and I want to know if I can use one as a grow bed for a flood and drain system.
How would you plumb the drain pipe through the glass?
By drilling a hole in the bottom glass.
Yes, you can. You may find yourself with a lot of algae if you don't cover the sides.
I see, so the light being let in will cause the algae? Thanks, good point. I was also condsidering building a plywood box and putting a liner in it. Any issues with that way?
Yeah, the light will promote algae growth. You can do a plywood and liner box as well, just make sure it's strong enough to hold your water volume :)
Thanks Matt. I agree about not seeing anything inside being a waste, but I have the glass already, so I just need to buy silicone versus building/buy a box for plants. How is your system set up? Do you have two pumps?

I have 2 glass tanks plumbed into my system at the moment. I use them for fish though, kind of a waste in materials to fill it with medium and not see anything inside it. I plan on using a 6'x1'x.5' tank rafting watercress with small ornamental fish or shrimp swimming through the roots.
Sounds cool. Pic's would be great. I'm trying to get my system start/built soon and I don't want to spend any more money then I need to.
