rock curing

[Myka]

The idea that the rock will reduce the nitrate on its own is correct. Anaerobic bacteria will convert the nitrate to nitrogen gas and that will bubble out (not usually seen). If those bacteria aren't there or the rock is not suitable for the anaerobic bacteria this won't happen. It could take several months for the anaerobic bacteria to colonize in population significantly enough to consume the nitrate.

Dose the bejeezus out of the container with vodka and MB7 and make sure there is high flow in the curing container.

I haven't actually done this but it wouldn't be very costly and should help drive out phosphates bound up in the LR and speed things along.

It is correct in theory but denitrification requires a carbon source, whether it simply occurs naturally in our aquariums is a very debatable topic.

Keeping your rock high nutrient water will cause you problems in the long run not just a longer cycle.

ok so jsut to clarify things. i should just do water changes till the nitrate is at 0 and stays there for a week then it is safe to add to my reef. its 50 pounds into a 125 so its a fair bit. just dont wanna get this wrong and cause a crash haha
