On, Under Or As?

[Noahs ark6]

Hi

Would this substrate be used on top of the sand, under the sand or as the main substrate?
thanks

under.I have it under my gravel, and it clouds like a bug*er when you disturb it

There's no point putting anything under sand, sand will eventually blend and sink into anything you put with it.

Plant substrates like that need to go under gravel else it will go everywhere.

but you see lovely planted tanks with sand in? how does that work?

 

[stu40]

nutrients come from dosing the water column (daily or weekly) using for example TPN+

so cat litter and does = nice planted tank?... or ADA aqua soil and no dosing?

some plants like amazon sword, are heavy on getting nutrients from the soil, so you cant just say the get it from the water column imo

Not true, I use clay and florabase under sand and it works perfectly.
