That, unfortunately, did not cycle your tank.It was cycled using seachem stability for 1 week.
Read this about the fishless cycle. That's how to cycle a tank. It'll be helpful for you to keep the link handy. You'll need to feed your tank an ammonia source on a daily basis for about a month on average before livestock like shrimp can be moved in.
Adding all of those shrimp (plural) to an uncycled tank means they're all going to die unless they're removed, unfortunately. It's going to take several weeks for your tank to be ready for them at minimum.After the 2nd week, I tested the water and nitrite/nitrates were all at 0 so I added 50 cherry shrimps.
It's that the tank is just now beginning to cycle.Is it the fertilizer? Or is it the seachem stability that didn't work. Or is it the dead 20 stems or so of jungle val or something else?
Yep. This is what's occurring.I’m assuming the tank is just now starting to go through its cycle.
Remove all of your shrimp and keep them in a separate container. They can't survive ammonia, nitrite and the like. Keep them in a bucket or something, dose it with Prime daily and do daily water changes until your tank is ready for them. Leaving them in the tank means certain death.At this point what do you suggest I do besides dosing prime/stability and water changes.
But you can do it. It won't be a daunting task. Just take it step by step.
