I'm running a MRC MR3 w/ dual becketts, a 12" riser extension, one of the becketts has the u-tube mod and last night I added a 1" OM omni-flex to the other beckett to flow the bubble column to increase the contact time. Not sure if the OM omniflex works or not but we we'll see.
Now I have two ideas I'm throwing around right now. The first is to upgrade to a deltec or H&S NW skimmer or...
I'm thinking of building or having made a new lower section of the MRC made that is a RC style, but with a 10" or 12" base that necks down to 6" and then to the standard MRC cup. Not sure what direction I'm going to head with it yet
I just sent out payment for me new RK2 2400. I will post pictures in about a week when it shows up. I was told its about 9 feet tall and has a 15" diameter body. Cant wait to see what it pulls out!
I have an aquamedic twin on a 200 g and a DIY with only one OR 3700 for recirculation on another 200 g. I don' t know why but my diy outskims the twin???? it uses only one pump but has more options for tuning and a smaller riser neck. I have an empty 500 g tank in my garage to be filled when my house is renovated, I plan on running a new DIY (to be build) skimmer with a 38 cm diameter tube and 3 OR 3700.
This 7 foot tall skimmer is air stone counter-current gravity fed from the overflow. It uses one Alita 100 air pump delivering 100ltr/minute at 120W through eight 3" air stones. That's it.
I change the stones 1x/month and clean the skimmer body with a magnet cleaner.
Here is a FS with collection bucket bottom center.
Here is a shot of the collection cup:
Better shot of the collection bucket:
Due to the explosive nature of that much air pressure, I have recently rigged the collection bucket with a float valve that signals the ACIII Pro to shut of the air pump and sound an alarm.
My collection cup should be larger: (older shot with old rubber gasket)
