Just wondering what is on the market that is cheap and safe to use other than the regular unipac which when buying quite a bit is a bit expensive
Or your local gravel/aggregate pit...When I lived in Notts there were plenty of gravel pits mined for their alluvial and glacial deposits. I don't think I ever paid for aquarium substrate.Go to the beach and get sand for free.
Cheers,
