I got woken up yesterday morning at 5:00am to a flooding tank. For some reason my overflow stopped flowing. I got it to start again and and a couple of hours later it stopped again. Every time I'd go to suck the air out there wasn't any. I have no idea why it kept stopping. I was also using a 35 gallon bin as a sump. It would not fit very well in my stand so I've been waiting to change it. I ended up buying an overflow and made a new sump. I'll attach a few pictures. Right now you'll see a a drain towards the top left of the sump. I'm planning on having that drain into a bin where I will relocate my condenser pump for my automatic drip system.
