New Pentair Superflo VS started loud humming noise

[xrabbi]

Pool and pump are less than a week old. Pump has run very very quiet on low speed (1400) without any issue but today, after pouring 2 lbs of stabilizer into the skimmer, the pump began making a buzzing sound you can hear in the linked file below. It may not be connected to pouring in the stabilizer but it was definitely not making this sound over first 5 days. The sound either disappears or is overpowered at high speeds (e.g., 2500). Any ideas? Thanks!

Never pour any chemicals directly into the skimmer.

In your other thread you show your pump well below the pool level. Are you getting full flow from the pump? Is the stabilizer hung up in the pump basket? What is your filter pressure like?

x,

Hopefully the problem will go away as the CYA (stabilizer) devolves into the water...

As Marty points out.. Never add any chemicals into your skimmer...

Thanks,

Thanks, so strange, the bottle says right on it to sprinkle into the skimmer but guess that was not best idea
