when i first started my tank i didnt know about sillica sand leeching and what not, but now upgradeing my tank i want to get Arragonite sand, but i have lots of life in my current sand bed and it seems a waste to just flush it all away.
is there anyway i could keep the life but not the sand?

i have thorght about a fine sive but that would only keep the larger life forms does anyone else have a better idea?

cheers james

Hi wozza,

You can save some 1/2 inch of the top layer of your current sand bed, providing that particle size and distribution is acceptable for your new sand bed. Everything else should be discarded.
Here's a link to an article that will help you understand the working of properly constructed sand bed, animals that live in it and so on.

How Sand Bed Really Works

thanks zhenya ive read that article before

i would like to get rid of the old sand and have non of it in my new system, because its made out of sillica and thats no good because of the leaching of sillica that fulles alagl growth.
but im pretty sure you knew that anyhow just stateing why i dont want it.
so other than siving any ideas?
