FS: Knop reactor with CO2 tank

[mkirda]

This is going to be a great deal for someone.

$150 for the entire setup, 15lb CO2 tank still mostly filled, Regulator with Dwyer needlevalve/flowmeter.

All you need is some aragonite media and you are good to go.

PM me for further details.
Located NW side of Chicago.

Regards.

Bump again. Nice setup at a nice price.

How wide is it at its widest point?

 

[mkirda]

The white base the Knop is mounted on is 11" wide. It is about 19" tall with the top sticking out.
The tank is 11" wide with the regulator attached. Could be up to 12".

Hope that answers the question.

Regards.

[DopeCantWin]

I think you meant 11" long, how wide is it?

 

[mkirda]

Think of it this way... It will fit into a box of these dimensions:
11"x 19" x 4.5".

Hope that answers the question.

Is it supposed to be fed with RO/DI water or saltwater from the tank? What zip are you located in?

He's not too far from me, so let me know if I have to play middleman

Saltwater from the tank. Best to use a valve from a return or similar.

Its the smaller knopp reactor good 4 up to a 180 gallon tank

I use a maxi jet 1500 to drive the large 1 I recommend a separate pump

I used it on an ~400 gallon system for roughly ten years. You need to adjust the CO2 output and make sure the effluent is put into an area with lots of turbulence to gas off any remaining CO2.

A Maxijet wouldn't work well at all for this application. A small tap off a return with an adjustable feed is best. I suspect I have mine left and would be happy to include it with the sale.

wow, you must have been refilling it once a month on a tank that big
I use to use a small tap off the return, but it just kept clogging up so I went with the maxi-jet & it solved MY problem
hey don't get me wrong your offering a GREAT deal it's worth at least twice as much as your asking

Sometimes, yes, if the calcium was lower than I needed. Just part of the monthly maintenance cycle.

Reactor is fed with thin tubing, so no idea how you'd attach that to a MaxiJet. Think air line tubing. Never really had issues with it clogging. Open the spigot fully and it would, well, think Race Horse.

Bump.

I don't understand why I still have this.
It is a seriously great deal.

how do you monitor the pH inside? it doesn't have a pH probe

Put a cup at the outlet, fill and measure the pH.

You can't do continuous measurement on something like this due to deposits on the probe.
