I have an ugly 55 gallon tank I keep outside and have been seriously been considering making it an NPT. I live in the desert so it's on my covered porch and it'll stay warm and have partial to full sun. I re-siliconed it but found a leak so that needs to be fixed. Already in there is miracle grow organic soil with a sand cap. I added a little bit of anacharis and some floaters but plan to add more. I haven't gotten too far into this so I don't know exactly what the temps will be. Starting today, I'm recording the temperature to see what I can expect.
My question is, what plants are hardy enough to withstand temp swings? I'm not really wanting small plants. My idea is maybe set it up like a pond but in an aquarium. Other than pond plants though, can anyone tell me what might work?
