Lunchbucket--I did revamp my sump system, so probably stirred up some stuff...but the foaming really isn't the problem. If I turn down the air so it doesn't foam, I still can't get much more than 120 gal/hr flowing thru it without it overflowing.
Cristina--I bought it from Salty Critter because I have a wholesale account there. The unit came without instructions so I called Reeflo to get them. They were emailed the next day. Then I had more questions, so I tried to get back in touch with the person I spoke to about not getting the instructions but could not get a response. Before I new it, the weekend was here when I had planned to set up the skimmer. (I wanted to buy from Mike but he doesn't sell wholesale, so I don't feel right about asking him for help. Maybe I should have spent the extra couple hundred dollars and purchased it retail from him!)
Spongebobby--the outflow is turned all the way open. The top of my T is about level with the midpoint of the beveled section. I just set it up last night.
Thank you all for helping me. I suspect that everyone is using the large cup, and I'm convinced that when I get mine, that will solve my problem. (I'm on a waiting list with Mike to get one). In the meantime, I think the only solution is to lower the level of the T....but this will be an inconvenience since a lot of water will drain out when the unit is shut off. But I think this is what I will need to do until I get the large cup. Without the large cup, it is my opinion that this skimmer is worthless for the size tanks it was intended for (if it can only handle 120 gal/hr with the T in the position where it should be).
Mike...if you are listening.....is there any way you can get me a large cup sooner? I'm now afraid my 500 gal tank will suffer if I can only run this skimmer at 120 gal/hr for a long period of time. I would be most appreciative if you can! Thank you!
At this point, the best help from anyone, outside of helping me get a larger cup, might be to direct me to a place to get replacement grey pvc fittings since I need to cut and lower the vertical pipe.
Another thought is for me to find someone who works with acrylic and have them make the larger cup. If anyone knows who I can contact for custom acrylic, that might be helpful also.
Thank you.
