sorry, my Aqua C is an EV-180 (not an EV-120). It will handle up to 200gal tanks.

These are normally around $490 retail.  Since I already have a skimmer I'll take $175.  

DOS, DDR, MP10, small reactor sold, 

Added to the list:  Etekcity PH meter, Vertex Reactor, and AquaC EV 120  Protein Skimmer

Hi All,

Some of the items are sold, and I have a few more items to sell - a Vertex Reactor, and a New Aqua C Protein Skimmer. Some items marked down to move.

I agree. Too much pressure not good. My tank water enters the pvc just before the recirculating pump. My Co2 comes into the pvc as the water gets sucked back to the pump. This prob causes some suction on the Co2 pipe.

I’m going to put needle valves on each end. Limit the incoming flow and control the outflow, That  should work hopefully.

you dont wanna "pressurize" the chamber too much in my opinion.  you definately dont want so much pressure where you are fighting the CO2's input from ever reaching the system. so if the valves are in the input, everything in the system gets pushed out as you put it in.   if you put the valves at the end, you create some backpressure.  minimal backpressure is good, and probably helps the valves from not clogging, but it will be a little harder to fine tune. both methods are pretty equal and it just depends on how it works out for you.  so.. thats the main take-away.. you cant reach water psi above the co2's input psi or you are fighting the co2 regulator.

That makes sense, thanks!

I’m thinking a prefilter on both ends would be a good idea as well? Or would that be overkill?

i have a ball valve coming of my manifold, then the needle valve for fine control.  ball valves over time become very inconsistent and hard to get in the exact spot when you wanna dial something in.

Agreed, I’ll put one on both ends. Thanks

Sounds like I need a needle valve on both ends? I have high end ball valves but they do get calcified over time. I also like to set and forget the manifold for the most part so I’ll pick up another needle valve.

I dont have one on my GEO. Its the old version of the 818.  I do get some bubble accumulation at the top over time. Gas should rise to the top of the second chamber. As long as you dont put the end of the dripper hose in the water any gas should come out into the air. You could always hold the end of the dripper up higher than the chamber. Shake the chamber to purge any excess gas. Maybe once a year. i duno

Makes sense, thanks

Do I need to put a tube at the top of the secondary reactor to outgas? My  Bubble Magus doesn’t have that. If so what do you recommend?

Ok, thanks guys! 

That makes sense on the secondary output (move the output to the top of the reactor). I’ll do that. 

I’ll use the ball valve on my manifold to control the input into the CaRX as I had planned. 

I have the needle valve in hand and the prefilter. I’ve heard a pinch valve is more reliable because of less hw in the water. I think I’ll stick with the needle valve and prefilter on the output for the moment and look at adding a pinch valve if I start having issues with the needle valve.

So put the needle valve on the water coming in from the tank? I have a ball valve on my manifold, is that not enough control? Also leave the effluent output with just a pipe/tube, no way to control the flow?

ATO is new in the box. I’ll put up a pic tomorrow.

Apex DOS and DDR sold. 

Small Reactor spoken for. 

Thanks! I’m not sure which secondary I’m getting. I’m looking at a Geo SMC410.

I pmed you April, both are available

How is this looking?

Yes, the DOS is still available, I PMed you

Hi All,

Isn't the pricing showing? I posted it with the items above.
