table is draining reaaalllly slow

Hi everybody, I set up my flood and drain system, and it floods fine, but when the pump turns off, it takes like an hour and a half to drain fully. I have my table sitting on top of my reservoir, tilted down slightly for drainage, and I have my two fittings in place. Everything is brand new and hooked up correctly so I don't know why it's draining so slowly. Please help!

i suspect a grorock in the hose, the pump pushes it up but when it's draining it sinks back down and clogs the line... well just a possibility

I figured out the problem. My pump hose was too long, so when I connected the hose to the table and set the table down, it caused a kink in the hose line. So all I had to do was cut a few inches off the hose, reconnect it and voila, it's working perfectly now.
