Can I use hydroballs in a fish tank?

[Froggylove78]

Hi learned fish friends!

im in the process of upgrading my ADF/guppy tank from a 10 gallon to a 20 long. I would like to create a shoal/ledge area for some visual interest and, having torn apart my vampire crab enclosure have cleaned hydroballs and bio mesh available to use.
My question is - are the zoo med hydroballs safe to use in my aquarium?
I olanned to design it much the way I did the paladarium: filter sponge to keep the area shaped, hydroballs behind it for height (about 2.5”) cover with bio mesh, then sand/gravel mix a top it. I figured this might be a lovely way to get some good roots on some of the plants I have as well (Anubias, Java fern)

all thoughts/ advice welcome!! Thank you in advance!

I had to Google that to understand what hydroballs are.

I've never used them but.. I would side that they are fine to use. Especially that they are for use with frogs and inverts.

I use them in my mourning gecko water feature and nobody has died yet! I’d also side with probably fine.
