I just got done setting mine up! I'm surprised at how well it works! It's going to run till tomorrow night for my leak testing and then I will be setting it up for real on the tank!
oshanickreef are you pushing or pulling withe the pump? Also do you have lots of air in the Geo, reason I ask is I have the Geo 618 and just put a master flex on it. I had so much air/gas inside my recirc pump stopped working. I had to pull pump off line and go back to manifold feed and ball micro ball vavle.
Thanks
Rich
nice set up.
Everytime I see the digital unit it makes me want one. I just might have to sell mine...and get one...
By the way, looks like you can add some more media to your reactor.
Thanks, please let me know what happens when you install gas.

Tkereacer619 is the man to talk to. He sold me my first cole parmer pump, and I have since bought two more off ebay. I run my calcium reactor off the one from him, and I run my auto water changer off a dual head ebay unit, and my sulfur denitrator off another single head ebay unit.
When you buy one off ebay, you should have in mind what level of noise is acceptable to you. The digital drive type is more expensive, but whisper quiet. That is the type I got from tkeracer. The variable speed console drives are very accurate as well, but a bit noisier. All my equipment is in an unfinished area of my basement, so noise is not an issue for me. But if your equipment and the pump will be located in an area you need quiet, you may want to pony up for a digital drive type, which is more expensive. I got my two variable speed console drives for about $200-$220 each with an Easy Load head on it.
I have my CP pumps pushing water through my reactors, but may switch to them pulling from what tkeracer posted above about them overpowering o-rings on reactors. Should not be too big a job to do that.
Another thing I would look at regarding these pumps is your pump head choice. Easy Load heads, wether Easy Load I, II, or III, are the way to go for ease of use. And, I would also look for the Easy Load pump head models that accept the greatest variety of L/S tubing.
The wider the variety of L/S tubing the pump head installs, the more flexible the pump is in its uses, in case you ever repurpose it. A pump head that only accepts 3/8" ID tubing suitable to run an auto water changing system may not be very adjustable if you are only trying to dose 2 ml increments of amino acids should you use it for something else, whereas a pump head that accepts 1/16" ID to 3/8" tubing is.
If you buy a digital Console like the first picture I posted below, the tubing ID may not be as important, as you actually program the tubing you are using and the desired ml/minute rate, but I think the majority of users will buy the less expensive AC motor drives like I have pictures in my last two pictures.
Also, if at all possible, buy variable speed and reversible drive units like I have in the bottom two pictures below if you do not go with a digital drive. They make it a lot easier to adjust amount and flow rates.

hi AA,
I just saw your posting of the CP unit (2nd picture) that seems exactly as the one offer to me by my local dealer here.
The model number is 7518-10 , I think yours is 7518-00. I wonder how is that machine running this time ? How is the noise factor ? As I don't have basement fish room like you guys so I wonder if the noise is acceptable ?
How is the tubing connections ? We don't have John quest here so any advise on possible alternatives ? By the way what tube size you use then? I am looking at flow rate of 15 ml / min at the moment and may be increase further when corals demand getting higher .
Hope to have some of your sharing .
Cheers,
MD
Check your private messages.Thanks Slief for your very helpful comment and suggestions.
I just sign in with ebay and never have any experience on how to buy from that site.
I have been surfing eBay to find some better model and better prices because I have removed my initial wish on brand new cole Palmer unit as prices is way too expensive for my target.
I am interested with your suggestion about some Japanese sellers on their much better model and if I can find one then that will be my option. Perhaps you can lead me the site to search these Japanese sellers.
Also I wonder in case I bought from eBay and if the unit turns out to be not functional considering this is across the sea buying , how can I return or make claim by then?
This is also my concern in buying with eBay.
Cheers,
