View Full Version : Substrate grain size?

11-07-2009, 02:28 PM
What grain size is best for Sagittaria, Cryptocoryne, Echinodorus, or Vallisneria? I have been using BB-sized material but I seem to remember a recommendation to use finer-grained material. I want to keep things pretty simple - no fancy substrate, no carbon dioxide setup - but still encourage root growth. I remember when i was a tadpole back in the late 50s and early 60s, all I could find was the Hartz Mountain sand and I got great root growth!

Sorry to ride your thread Cryptfan. I just want to add something to your question for the answerers. Is playsand too fine to grow roots?

Pool filter sand is cheap and effective, it comes in different grades (sizes)

The sag and Vals are what is going to do better in the sandier substrate, they spread by runners.

Mang: Roots will grow in water, so I dont believe there is any substrate that it too fine for the plants, maybe too fine to keep on the bottom though. Play sand works better if you wash it a lot first, and you want to make sure its inert (will not change ph) so no shells or anything like that.
