Calcium reactor problems

[Shirak]

Well you can try putting the Kamoer on the input side of the reactor. Have it pull water from the tank and push into the reactor. If there is any connections that are not air tight, you will get water leaking out.

CO2/air bubbles building up at the bottom under the media? I have never heard of anything like that.

Yes , it's 12 dkh .
There is HUGE buildup of co2 at the bottom the reactor , I need to move the rector gently to realse them .

How fast was the pump running in the first video?

That's exactly what I did...I tried pull and push ,the result is the same.
I know that is sounds insane and I wish that it wasn't the crappie situation, but that is the really right now.
I'm willing to do everything to fix this issue.

35 ml/minute

Here is the test that I did today

I don't understand what you are trying to show with the second video. Looks like it's working to me. The circulation pump should be chopping up any bubbles entering the pump into micro bubbles and pushing them out the bottom tube to work their way through the media where they will go back into the pump and circulate around over and over.

Photo just to confirm connections. The Kamoer can go on the in line from tank push mode or on the line back to tank in pull mode.

I was watching your first video again and not sure why the line from the pressure regulator is white but the line going into the reactor bubble counter is black. Also looks like you have the Kamoer set in push mode so it is not possible for a bad tubing connection to be sucking in air.

Have you checked the circulation pump to make sure nothing got in there to clog it up or damage it?

My point is that the recirculating pump barley drawing water/bubbles from the top of the reactor .
The ph inside of the reactor don't go down ,no matter how much co2 is been added to the reactor. I replaced new probe of GHL , and new milwaukee MC122 ph controller gave the same result.
Since the beginning the recirculating pump was making a lot of chopping noise, imm guessing that not only of co2 , it was also air (my guess).
Because of that , it maybe don't work properly.
The color of the RO is white because I changed from pull to push and needed extra long tube.
I know for sure that I did everything according to manufacturer instructions, but it is not working.
12 dkh and ph that doesn't go down Is definitely not the right way .

I'm reefing for almost 18 years ,and know how to deal with technical issues (most of the times).this specific situation is beyond my limits/understanding.

Can you adjust the angle of the suction tube at the top so the top of white elbow is closer to the lid? Only thing I can see really. It looks like it is sucking in water. I don't think it's supposed to really clear all the bubbles off the lid. It will only grab what's close to it. You should hear a 'chopping' noise when bubbles go through the pump. Especially every time the CO2 bubble enters the reactor. The elbow looks a little skewed?

I was reading about the pump on the GEO website and it specifically said it was a lower flow pump. So I would not expect it to suck all the bubbles from the lid.

DKH and pH will depend on how fast the water is flowing through the reactor and amount of CO2 entering. Slower flow/Higher CO2 will increase DKH and lower pH. Have you checked your Kamoer to see if you are really getting 35ml/minute by collecting the water going back to the tank for one minute? Maybe the flow was more than you were expecting which is keeping the DKH around 12 and pH around 7.1? Clearly it's doing something. The CO2 bubbles in the first video appear to be going through the pump. Maybe it just needs more time and some fine tuning for CO2 and effluent flow?

Kamoer pump was calibrated to 30 ml/minute.
Ar the first video it's 30 or 35 ml ,I don't remember exactly.
The 90 pvc elbow is directly under the lid.
The fact is that at first 2 weeks it gave Me 35 to 45 dkh ,in 30 ml%minute effluent, at 6.6 ph .

Now ph don't go down , their is massive buildup of co2/air bubbles , and dkh of 12 ,maybe less.

I have daily consumption of 2.5 dkh daily in my tank , that's the main reason that I switched from balling method to Carx .

I still do not see a working video. Please send me a direct link to my email. [email protected]

Thanks , I sent you link to your email few minutes ago .

The forces at work will try to pull air in right here. This looks like the only spot where there is negative pressure.

I will send geo another very specific video to GEO ,with all of the details

The GEO instructions call for a power head and a pinch valve (at least the old ones did). I had similar issues when I tried to use a peristaltic pump and pH control. Good luck and keep us posted... I think you will get this to work.

I'm sure that there is solution for that .

 

[FishTruck]

Yes… use the peristaltic pump as the pitch valve. Win:smiling-face-with-sunglasses:

Hello everyone, Ita been a while...I finally understood what was the problem - the co2 regulator was not sealed...it was taking air and co2 together and caused me those problems.
Thanks to GOE costumer service , they are great !
The reactor works now perfectly without any issues.
It works in pull method, and dkh at the influenceis 40 !
I'm thinking about ordering the bigger model , the 818 .
Thanks everyone for your help !

Happy this is resolved. Everyone on this thread contributed in good spirit! That’s what this forum is all about. This was a tough issue to resolve. I will put this one on the list of items to check.
Thank you
GEO
