Substrate

Is it OK to bleach substrate?

[lockrookie]

i would have to say no.. bleach in your tank would kill everything. you maynot get it allout of the substrate and each into your tank .. rince it very well with fresh water or ro water or throw it out and add new.

You can but why? Rinsing it is a better option .Take small amounts in a bucket and blast it with a hose until the water runs clear . Repeat untill all clean. If you bleach it all the nasty stuff will be still be in the sand .

It's stuff that gets sucked out when vacuuming, wanted to clean it and put it back in.
New substrate is over an hour away, will get some the next time I'm there.
