Yesterday I went to the hardware store in an attempt to find a good floating material. I came back with what the associate called neoprene foam. From what I read, the small bubbles in the neoprene are individually enclosed and the material gives when pressure makes the nitrogen gas inside contract. If this is true, they should remain buoyant. Since they make waders out of the material, I am assuming this will work.
I cut out a few pieces, made floating water pots, and filled them with expanded clay and plants.
Do you think the pots will remain floating in the long run and under a heavier load?
If so, I can cut them back to make doughnut floaters like the pot on the left. This will allow more light to my immersed plants and be more aesthetically pleasing.
I am using water pots from a local hydroponics store. The vents are quite large, making finer soil difficult. Do you think I need to provide a finer substrate with more nutrients?
I'm guessing it also depends on the type of plant. I do have some pantyhose left over from making my 20g shrimp safe...
Eventually I want to add more color. Any suggestions for low humidity plants and sources to purchase them?
I'm sure I can learn quite a bit from this experiment, but a little head start would be nice. Any other advice you can add would be great. In the meantime, I will be browsing a ton of riparian journals.
