Who Gives A Fish Forums

I've noticed my torch does best when the flow is just enough to make the polyps sway slightly. Anything more and it retracts.

I completely agree, setting up the substrate now will give the current plants time to settle. If I were to start from scratch, I'd probably go with Seachem Plant and Shrimp substrate, it seems like a hassle-free option that would promote healthy growth and happy inhabitants.
