I've seen some discussion on here, but not sure if I need one. I'm installing a SWG and need to figure out if I need a Zinc anode. From what I can tell, it would have to be in-line. But every discussion that I see relates back to the heater. I don't have a heater on my pool. The only metal in my pool is the LED pool light. No steps, stair rails, etc. Whisper-flow pump and DE filter.

So do I need an anode or not?

Thanks!

I don't see why you need a sacrificial anode. You have nothing it needs to sacrifice to save.

Hey Beej !! The water in the pool (which will have salt in it no matter what) will harm any materials that aren't of good quality. The 'salt pool' is only 2 or 3 times the salt content of a traditional chlorine pool, and only 10% that of seawater.

The annode is nothing but a weight while lightening your wallet.
