I had a saltwater fish only tank for a year. I've decided that I want to have live rock in my aquarium... I've heard of people saying that u can seed base rocks with some live rocks. wat is a base rock ? Can u experts outthere tell me how to do this? buy all live rock ? or seed base rocks with live rocks ??? I have a limited budget..so i would prefer the cheapest option. Thanks in advance.
the term base rock is use very loosely and streched very far today
If I buy base rock then it has been mined from cliffs close to the oceans. It is devoid of life and bacteria.
Live rock depending on how much dead and dying stuff from the reef has been scrubbed off it(curing) usually has been kept moist enough for the bacteria on and in it to survive.
It is this bacteria that is the biological filtration for your system
Live rock can come from different areas--eg Figi--and the live rock from there is very porous. You want this so it can hold the anerobic bacteria in the centre of it(aerobic bacteria break down the ammonia to nitrites and anerobic bacteria break down the nitrites to nitrates)
So if you buy base rock make sure it is porous, and if you use it with live rock expect it to take up to three months to fully cycle bacteria on and in it.
A normal cycling time is 6 weeks with just live rock in comparison
In your particular case you are better to cure the live rock and have it cycle in a separate container for the 4-6 weeks. Then introduce it to your FO tank.
This way you avoid ammonia spikes which can kill your fish
