I have a torch with 15+ heads. I noticed today one of the heads looks to be dying. All the other heads look ok and my other torch is doing fine. Is this normal or if I loose on head does that mean they will all die?
They should all be independant. If there are two really close, you might have to keep an eye on the other.
Did you check your nitrates and other levels? Anything change in the tank recently?
