Quick Cycling Q

When ammonia and nitrites clear within 12 hours, when should I redose?

Dose ammonia once every 12h or 24h?

Hi, the info I use:

Source - http/www.tropical-fish-success.com/fishless-tank-cycling.html

Add enough ammonia to read 2-3ppm. At this stage, you should be testing daily and noticing that your ammonia is near or at zero, nitrites are near or at zero, and your nitrates are rising. This means everything is going as planned.
When you notice after two consecutive days of dosing ammonia that your levels are stable and in the safe zone, you are ready to reduce the amount of nitrates in the aquarium water.

Perform a large 50-70% water change. DO NOT clean your filters, and DO NOT vacuum the aquarium gravel. Cleaning your filter and gravel would reduce your beneficial bacteria colony.

Dechlorinate your water and let the system run for a day or overnight so the water conditions can stabilize.

I'm processing 4ppm ammonia in 12 hours.  My nitrites are taking  a few hours more to zero.  So I've being dosing only when the nitrites have zeroed.

When both zero should I dose at 12 hours or every 24h?

Thanks for the article.  When I get my double zeros I will probably assess for at least 4 days to make sure the cycle is stable before the large water change.

Hoping for fish this weekend if everything goes well.

Dose every 24 hours

You should be dosing every 24 hours, as apparently it's better for the bacteria than every 12.

It's generally recommended you do a qualifying week, where you continue dosing every 24 and checking it's gone after 12 to make sure you're fully cycled and ready for fish and it's not just a fluke.

All sounds good
