Substrate ?s

[bobross]

Hello everyone,

Just a couple of q's regarding another option for substrate. The other day I was at a local lake and was grabbing some rocks for a tank and thought of something. All of the rocks I grabbed were in a really fine sand 'substrate' at the bottom of the lake, since I use all of the rocks from this lake(after boiling them), could I use the sand from the lake as a substrate(after sifting through it, picking out any impurities, & boiling it)?

Even though the lake is publicly (spelling) used, anything I've taken from it & put in my tanks is dried out in the sun, baked, then boiled for a couple of hours ...just to be on the safe side. - which is why I thought using the gravel would be okay. Can anyone help me out & let me know if it is/isn't okay to do?


Also, whether it's lake sand or pool/play sand I use, can I just clean it and add it on top of the existing substrate? or do I have to remove all the old gravel to add the new sand?



Thanks in advance,


BobRoss

As long as you boil it and stuff, it will be fine.

And if you have big gravel, i would say take most if it out before putting the sand in, because the sand would just fall between.
