easiest way to measure the flow is to put a bucket on the output line and time how long it takes to fill a certain amount of volume. Not super easy if it's all plumbed up but a simple task otherwise. If it's all hard plumbed up making that task undesirable drill and tap an 1/8 NPT hole in the output pipe from the pump somewhere, then you thread in a pressure gauge to measure pressure to determine flow rate. You can screw a plastic plug in the hole when you're done.
If you really want to hit that kind of volume you might need two pumps. Hard to believe a skimmer needs 4000gph turnover and require that kind of power consumption. Sounds like a new skimmer would pay for itself pretty quickly  Last edited by sphelps; 07-17-2013 at 02:28 PM.

Marko Becketts are power pigs. I have ran 21", 24,28,36,48,72" becketts you dont have to run that powerful pump to each beckett. When i ran my 72 " dual beckett I had a MAK 5 running it and had a crap load of head foam like 36" tall. if you can achieve about 1000GPH thro a beckett then you are golden. the trick is the pressure pumps thou. running a mag 24 will do the trick. However u will find that you will alot of head pressure due to it not being a pressure rated pump. if you want to talk more becketts are my speciality skimmers too. Like DC pumps are Sphelps fav to have knowledge about.
shoot me a PM with your number i can call you tonight if you want too.

Seems to me these Beckett skimmers should come with a pressure vs flow curve so you line up the appropriate pump. To just specify a flow rate makes no sense but then again the whole concept makes little sense, kind of like driving a lifted one tonne with 30" wheels downtown to work everyday.

Lol
The skimmer is running fine right now and skimming well. (With the addition of the air pump). I was just wondering if there would be a solution that could eliminate the air pump. I don't think buying a new skimmer would really save me any money for the same skimming capacity. How much does an energy efficient skimmer rated for 1000 gallons cost ? I feel like running a barracuda and a 65w air pump is reasonable power consumption for a skimmer of that size. But correct me if I'm wrong
