After 6 months of perfect parameters…..I decided to change my substrate from gravel to sand.
I left some gravel rocks in there along with all the same plants and wood.
But my worst nightmare is happening and my cycle has crashed.
I have low ammonia, low nitrites and low nitrates (which I know that one is normal)
I’ve never done a fish in cycle.
I have 3 electric blue acara cichlids, 5 corydora catfish and a pleco.
I will dose prime. But how do I get my cycle back on track??? Do I add some nitrifying bacteria?
I do plan to do a water change.
Thanks 🙁

changing substrate is restarting the tank
cant do much other than just wait and let the bacteria grow
keep feeding low
Your gravel likely held a lot of the bacteria that had your tank cycled in the first place. Just gotta wait it out! Are you using the same filter cartridge prior to changing your substrate?
