[Steve-O-]

So i was floating mine in my sump with foam before i planted them should i just do that?

[Proteus]

Yes oxygenated water allows for more o2 and nutrient to be absorbed in comparision to oxygen dissolved in water

Is "Hydroton" or whatever type of clay pellets you use, aquarium safe?

[Proteus]

I don't know if it is or not. But after you rince it it does not breakdown. As its fired clay. But there are many things you could use such as crush or marbles

I have a good supply of "Hydroton" (my other expensive hobby= orchids), I just don't know if it is reef safe. Is that what you use?

[Proteus]

Sweet I have a half dozen orchids. But about 45 house plants.
No I haven't used hydration yet. But it's food grade. So why not

I use small crush and lava rock

I hope there are no heavy metals to leech out.
