It's been awhile but things have been going ok. I got my water parameters back to around where it needs to be. KH back to 4 but I can't seem to increase GH past 5, even if I only add GH remineralizer back during a water change. Anyhow, the tank has been stable. I haven't seen many shrimp deaths or anything alarming. They are still consistently breeding. I do have to feed them much more aggressively, on a daily basis. I also started to add in mulberry and dandelion leaves for them to graze on every few days on top of the other foods. They are a bunch of hungry buggers.
I need to swap to a more powerful filtration system than a sponge filter system. While the shrimp poop is awesome for growing my plants, the water has become dank and dark. I'm fine with tannins, but there are way too many particulates in the water. Going to swap to a mini canister filter system with a spin pipe to keep water flow low.. so things are going to get shook up a bit again, but hopefully it all stays stable.
