Can I ask for some advice please?
In one sentence: Should I use rock from an old tank which crashed in my new tank even if it no longer "live"?
I have a 7ftx2x2 - 160 gallon marine tank which crashed a few months back.
I've stripped it, changed filters etc etc. Essentially its now a new tank and I am about to start slowly restocking in a few weeks when the tank matures.
I have 100kg of live rock from my old tank that, after 6 years in the old tank, wasn't much use as live rock.
It has been removed, jet washed and left to dry
I don't need it to be "live" rock in my new tank set-up as the bio filtraion is done elsewhere.
Should I use it as dry rock simply to save me buying another 50kg of rock that will cost a good £300
Or leave it because it might have lots of dry dead things in which could mess up my new tank?
What do you think?
Thanks for any advice. Gratefully received.
(If you're feeling super clever I have question about water flow through rock work in here too...)
