Finally found a use for bio rings

[seangee]

I haven't bothered with "bio media" for years and just use plain old sponge.
A while ago I did a big clear out and instead of chucking out all my unopened bags of bio media that came with various filters over the years I dropped some into my filters.
When I set up my breeding project I wanted plants that I could remove in seconds - and the tank has no substrate. My first attempt was 2.5" pots with a little sand (left of pic). This meant I had to plug the hole so for the next lot I put in I just used the pots upside down and pushed multiple stems through the hole (right back of pic). But the pots still took up a lot of space and I wanted to add more plants. Didn't want to spend money and also didn't want to risk any contamination from metals so I raided the back of an HOB et voila

3 Ambulia stems pushed through the hole and cut flat along the bottom. Time will tell if its heavy enough to keep them down when the plants grow up

I don't actually care what this tank looks like but I will be using the idea in the others, and it will allow nicely manicured shrubs with minimal maintenance effort

It should be enough to give the plant the time to root in the substrate for sure.

I used ceramic rings and PVC coated wire to make floating plant hanger. And it works great.

That's a nice idea, may give it a try.
These will never root because there is no substrate. That's a sheet of astro turf its sitting on
