Hydroponic: clay pebbles or rocks are made from pH neutral clay..

They tend to float too much. Any air trapped in them and they float. Plus, only the smaller size is small enough to consider as a substrate. I see no advantage to using them over using several other substrates.

It could be used for a shrimp tank substrate. I use ADA Amazonia substrate.

Much too large. The usual biological and chemical processes that happen in natural and constructed substrates can't take place.

I have think they would float as Hoppy mentioned. I looked at them myself in a hydroponic store.

Maybe just run a bare tank for a while?

Is there some reason you aren't considering other substrates available on the market?

Azoo Plant Grower Bed
Mr. Aqua
UP Aqua
Fluval Stratum
et al

They're all cheaper than the hydroponic stuff.

The pieces are quite large, about the size of a marble. I use them in my shrimp tanks as "bio balls," a site for bacteria culture. They are porous and will float, boiling them or soaking them in water for an extended period of time will make them sink. The other substrates somewhatshocked mentioned are good for shrimp.

They float away. They also are so light filter flow blows them away. It'll be an ugly nightmare.

To make it easier: just pick what looks best to you while reaching your goal. If you can buy it in the states, it's likely been reviewed here on TPT countless times.

Most of the mainstream shrimp-centric substrates cost about the same or are within $5 of each other.

I don't think you can go wrong with many of the products available today. It's a great time to be a part of the hobby.

If the hydroton is locally stocked, and if you have a food saver, or one of those vacuum cleaner shrink bags, put the hydroton and water mix in a bag and pull a vacuum on the container. Air out - water in.

But... if it is something you have to order, one of the other suggested substrates would be easier to work with.

I use hydroton in my hydro set ups. I would not use it in a tank. About half of them float and they're much too large for anything with fine roots. They're great for hydro or aquaponics though, as long as you don't move stuff around too often.
