Lol I guess the mystery is solved then. I didn't know you couldn't just toss their water in. I assumed they where alive in the lfs tank I figured mixing that water and tank water wasn't a big deal since I'm acclimating them in the same mix.
This is my first foray into non feeder shrimp so all these tidbits are very helpful. The drip method very much so. I had no clue...
Nitrate: less than 5
Other parameters unchanged.
I'm not understanding why nitrite won't drop but nitrate builds then drops builds than drops. It's like I'm loosing my nitrifying bacteria over and over. Almost like they colonize then collapse. I don't know what would cause that.
I am doing a water change after this post.
Haha duckweed is amazing stuff.
I don't know what to say about the cycle. I thought my test kit was bad so i went and grabbed strips and verified my test kit with them. They match results. I have bio max from well established tank inside the tank I have snails in tank I put fish flakes in it. Nitrites climb nitrates drop.
Duckweed is fast but the denitrifying bacteria should be faster. Have you tried completely overloading the system with ammonia? Either lots of fish food or just add some ammonia. I take the second route for my fishless cycles. I wonder if the fish food you added was eaten by the snails and therefore you only got a short ammonia spike which translated to a short nitrite spike. Maybe this doesn't make sense but I'm just throwing out theories.
I tried doing a window sill tank here in seattle, and I still had to cover the side that faced the window to completely block out the little sun we get. Shrimp did well but after a few weeks I pulled it down because I didn't like the fluctuation it was having.
