It says in the instructions that the gate valve is only designed to allow 700gph. Also, in the instructions, it details how the baffle, air valve, and other mechanics of the system were designed to run on a specific flow rate and that "tweaking it" could throw it off balance. They were very adamant about this topic so they must know what thier talking about. Plus, one of thier selling points was that it could skim just efficiently as the bigger boys could with less pump power.
POSSIBLE SOLUTION!!!!! I just got off the phone with another member and he said something that stuck in my head. I started having these problems about a month ago. About a month ago, I got tired of my 3 seio's slowly pushing my sand bed around. The seio's were positioned about 3 inches above the sandbed pointed towards the front of the tank. My skimmer worked fine at this point. I was getting tire of having to constantly flatten the sand back out. But under this arangement, I never had detritus on the dirt. I moved the seio's to about 7 or 8 inches above the sandbed to alleviate the sandshifting problem. I now have quite a bit of detritus on the sandbed. Tomorrow I am going to vacuum the sandbed, stir things up a bit, and reposition the seios to thier original position. Im wondering if this is why the skimmer quit working. Was all the detritus being allowed to settle on the sandbed opposed to being blown around the tank and eventually getting skimmed out? I will definately post an update tomorrow afternoon and let you know if this resolves the problem! I think this may be the cause of my heartache! :lol:
