I started cycling last night and used mature media out of my exisitng tank to give it a kickstart.
However, I filled the tank up with cold water the night before, then turned the filter and heater on last night, i.e. I put the mature filter media into cold water, did I kill it by doing that?
If I did, how long should I leave the new media that I put into the existing tank to replace what I'd taken out, before trying again? (I used half of a Fluval One filter sponge).
Cheers,
Paul.
