At the meeting Sat I was asked how the tank was and any more power outages. Replied no outages all good redid the backup so only 2 things in it; return pump and powerhead. I even returned the generator on Thursday night. About midnight I hear noise and the power went out again, of course. Threw the battery air pumps in and went back to bed. Woke up for work and still no power; so had to drive to stepdaughter's house to work. The tank is fine so far but come on - no problems for 3 weeks and now this. Talk about coincidence but wondering who jinxed me at the meeting....LOL
