What feed pump do you use w CaRx

[snowmansnow]

Hey guys.
What feed pump do you use with your CaRx? I'm so tired of having to fiddle w the needle valve because my effluent is inconsistent.
I'm using a MJ 900 right now which I know is probably this issue.
I tried a 1200 but it rattles horribly when under back pressure.

So what do you use? Are you able to keep a constant effluent rate?
Thanks
B

I'm running mine off my manifold, but it can be a little inconsistent at times. Thanks to UrbanKnight I was able to pick up a commercial IV machine. So now I just gotta figure out how to program the thing. Lol.

MJ1200 but eventually I'm moving to a manifold. It's not about the pump output because you need to control your drip rate anyway.

Maybe I'll look into this manifold business.
I don't have a lot of stuff though... besides the skimmer there is just the ca rx and a dual brs container.

Great finally meeting you today! I really appreciate it.

Manifold is quick and easy and well worth the effort.

Brett, tell you what, just give me the IV pump and I'll figure it out and then tell you. ;-)

Out of curiosity, what do think is causing the manifold feed to be inconsistent. I was toying with doing the feed that way, but if you're having a problem makes me second guess it.

lol this thing is complicated. Just the general flow and me being OCD. I get a slight hesitation between 4 fast drips on the flow, I think it's because I put it on the end of my 4 stage manifold or i may need to add a needle wheel valve instead of the valve I have installed. I have to check it every couple of days to make sure it's not clogging up and slowing down.

adjust the flow going IN to the reactor instead of out of.I've been doing it this way for years and my drip stays rock steady.

I do have it setup with my valve before my reactor. I didn't want to risk pressure building up in the reactor.

So throttle my mj back w a valve ... then open up the needle to the effluent all the way.
I'll try this...
Looking around for one of those nifty valves I have that fit it

+1

That's what I do too when I see the flow get slower. Open a little more from the valve (manifold) and turn it back down. Just have to watch for the pressure.

I use an Avast Marine peristaltic pump. Its configured to pull effluent from the reactor and into the sump. This prevents pressure from building up in the reactor. Output is a steady .4 gallons per hour

So how do you get water INTO the reactor?

1/4" line between sump and reactor input. Peristaltic pump creates low pressure in the reactor pulling water into the reactor from the sump. Instead of pushing water through the reactor I am pulling water through.

 

[hiimsean]

A lot of setups are using peristaltic pumps these days. Most are medical grade Masterflex pumps off ebay.

 

[elfloyd]

I started off using a Masterflex pump but needed something smaller to go inside the stand. I moved to the Avast Marine pump about a year ago.

 

[hiimsean]

Masterflex are quite large and can be noisy. I'm glad the Avast one is working well. How many mL/min are you pushing through it?

 

[bcavalli]

Anyone much smarter than me (not hard sometimes, lol) know how to program one of these to run 24/7?

That's an ingenious way to use it. I hadn't even considered that option. Thank you.
