Greetings All, I have been doing a fishless cycle on my IBC system for the last 13 days. Ammonia came down, nitrites went way up and I started seeing a bit of nitrates. Today I checked my water. All are down to ZERO.
Not really sure what happened. Anybody have an idea? I did use PH up to bring the PH back up from 6.0. Hasn't bothered it before.
Do you have any plants in your system? And how much ammonia are you adding every day? 275 gallons?
I am using a hydroponic PH called PH UP. I did ad more ammonia yesterday after the zero readings. The ammonia up to now had been running between 4 & 5 without adding any additional. I did use city water to top up.
I do have a few plants in the system. Herbs, peppers, cukes. I added a couple of teaspoons yesterday. System is about 550 gallons with FT, beds and sumps.
