Hydro clay balls

[ghostsword]

Hi, has anyone used Hydro clay balls on the tank?

I have a bunch of hanging planters for my tank and a couple of pots and I am looking for a substrate for it. Currently I am using rockwool and the results are good, but would like something more natural.

Thanks,...

Hi Luis,
They were my substrate of choice for my over-tank trickle filters, they float and you may still need a bit of rockwool till the plants get going. Flower arrangers "Oasis floral foam" is another possibility.
