Ary you using a controller?

tikalize · #3 07/28/2007, 12:20 AM

I have a Milwaukee controller but i am not using it to control my co2 output. I am only using it to monitor the PH in the reactor. Do you guys think i may have not purged the air from the reactor long enough? (Effluent valve open all the way, co2 off, Feed & eheim running? Thanks for the reply.

szwab · #4 07/28/2007, 01:33 AM

if your regulator's BC is bubbing but the reactor is not, it's possible there is a small leak in the CO2 line between the regulator and the reactor. Check your connections. Or open up the needle valve a bit more and see if that pushes the Co2 through. Even though both BC's should be under the same pressure from the reactor so if one is going the other should as well.

szwab · #5 07/28/2007, 12:01 PM

it's doubtful, but possible that the check valve is on backwards. Thus not llowing co2 into the reactor.

just a thought.

tikalize · #6 07/28/2007, 08:04 PM

Thanks szwab, I double checked that when i started having problems & it is installed right. I am using a brass check valve instead of the plastic one that came with the reactor. The brass CV has a arrow engraved on the body marking the direction of flow correct? Well my flow follows the arrow (in on the arrow side out on the opposite side).

tikalize · #7 07/28/2007, 08:16 PM

Well, last night i let the reactor run without Co2 & came home today free of bubbles. i will let it run like this until tomorrow. That could of been my problem because when i first put the reactor online i only let it purge for approx. 10 min before i introduced Co2. I will check for gas leaks with a soapy solution to make sure the system is leak free. I hope this helps. Thanks for all of your input....

NP. good luck
once set the bubbles on the regulator should naturally match the bubbles on the reactor

About a week ago I purchased brand new GEO 624 CR. I love the quality of it, but I'm having problem running it. Everytime I just the drip to what I want it is good for a day or so and then it stops dripping and air builds up in side the reactor. After I open the valve let the air out and adjust my drip it is good for a day and then again the same problem. Any idea why is this doing? Please help.

mcurl98 · #10 08/28/2007, 09:07 AM

have you been running it for a week? It takes a few days to get the air out of the media and to get to get it to work smoothly. If you've been running it for a week, it might be that your CO2 rate is too high for your drip rate. A very slow drip rate with a very high CO2 rate can cause the excess CO2 to form an "air" (co2) pocket at the top of the reactor. Are you using a controller?

RokleM · #11 08/28/2007, 09:23 AM

Two tricks I've found. I do this primarily after a media change, but it can also be handy after a power outage (although it's not as necessary):

1) Tip the chamber slightly to the side and angle the air towards the probe holder. You can very carefully unscrew the probe holder to let out air/pressure. The pump will refill that space with water.

2) Combined with the above, a few light taps on the side of the chamber will dislodge a lot of air bubbles in the chamber

Obviously do this at your own risk. I can very easily tip the chamber as it's near the edge of a table ledge. I just slide the chamber over the edge and tip it gently in order to not create unnecessary pressure.

My drip rate is faster then my CO2 rate. I do let the air get out of the chamber and then turn on CO2. And yes I do have regulators on it. I will try to push the air out as much as I can and then try it again. Thanks for the help.

mcurl98 · #13 08/28/2007, 01:04 PM

shaking it works well during the first week or so too to get the air out. I actually meant a controller as opposed to a regulator. With a controller, you can increase the bubble rate but keep its duration short so air does not build up.

Is the conclusion to my problem that when there is air left in the chamber it will create (siphone like action) and stop dripping? Do I have this right?
I will take one more day to try to clear or the tiny bubles out of the chamber and then try the drip and see howit goes.
Thanks everyone.

mcurl98 · #15 08/29/2007, 09:34 AM

If there is air at the top of the chamber, the air will be pushed out the effluent line before the liquid. One final thing I did was turn off the co2 for a couple days and run the drip valve all the way open. Are you feeding it with a MJ1200? Also, are you running large grain media? I have a 624 as well. It is a big reactor and a lot of air can got trapped when I added the media.

At this point there is no air at the top.
The co2 has been off the last couple days.
The drip valve is fully open.
I am using the Maxijet 1200.
And yes I am using the large media.

well, if it doesn't work, post to this thread. While it is a Korallin thread it has turned into a general reactor thread. Jdieck seems to know everything about reactors and is very helpful.

anybody know what's up I can't get on I am buying a used 618 and I want to download the manual the Geo's site isn't loading been a couple days now.

Phyxius · #19 09/07/2007, 04:09 PM

Labman48076,
PM`d you on this. Have the pdf I can give you of it if needed. Or try this link
GEO Manual

Matt it works like e charm right now. I ques the little air left in it was the problem.

docwells · #21 10/31/2007, 07:34 PM

Are there any Geo skimmer users using a feed pump to feed the reactor instead of gravity feeding? If so, what pump are you using. I think I remember Geo saying a needed 200-300 gph throught the skimmer.

Also is anyone using a perastaltic pump to feed theie calcium reactor?

Thanks

mcurl98 · #22 10/31/2007, 07:47 PM

I use an MJ1200

docwells · #23 10/31/2007, 09:01 PM

Thanks mcurl98. I was thinking about a MJ1200. I wanted to see if there was anyone else who used it.

szwab · #24 10/31/2007, 09:17 PM

i use a 1200 on my reactor but I'm sure a 600 would do the trick.

whoops never mind just noticed you were talking skimmer, mine is gravity fed.

mcurl98 · #25 11/01/2007, 12:11 AM

I was talking about a reactor---CA reactor
