My tank wasn’t doing good and lost a lot of corals recently. Today the jebao sow8 I had for about 4-5 years was running slow so I took it out to clean it. The inner magnet seal broke and it’s rust like a mofo. Perhaps that’s what killed some of my corals. Check your gears folks! And prob stay away from their products too. I had been always a fan of them till now SMH. Sent from my iPhone using Tapatalk
