Durso is acting up

its been a while since I posted, but here is my latest issue...

My drain seems to get an air bubble or some sort of backpressure that prevents it from draining. To fix the problem I just lift the drain hose up and out of the water and then it works fine, until a couple weeks later it will happen again. The return chamber in my sump is small enough that I am not risking an overflow, but it does make my pump run dry and the water isn't getting filtered or skimmed. This also isn't a huge issue as the tank is in the office and I have already trained the secretary on how to fix it. However, if it happens over a long weekend I am not sure what condition we would find the tank in when we got back to work.

Here is what I have done so far...

1. Aspirated the durso with some airline tubing (didn't work)
2. Replaced the drain hose with a new one incase it was fouled (didn't work)
3. Opened the valve on the T on my return line a bit to lower the flow through the tank (also didn't work)
4. Cursed loudly and repeatedly at the tank (didn't work but made me feel better)

any thoughts?

Have you checked inside the durso to see if anything was clogging the actual pipe? Is the drain line completely submerged?
