Right then, this tank is empty now, I have moved all the shrimp to this tank
I still have this tank running, but will break it down soon and sell it. It just wasn't that shrimp friendly and I had to do a few workarounds to make it safe. Hopefully the new tank will be a good home for them. I'm still glad I bought the tank though, I learnt a lot, but from seeing other setups and it not being that shrimp safe, it was time to upgrade.
Thanks again for everyone's comments and inputs, appreciated
