Korallin Calcium Reactor

[smoke15]

I believe my reactor is dialed in. However, I get alkalinity at 12 and calcium at 360. How should I correct this?
Should I try and dose turbo calcium?
People still do kalkwasser even after you get a reactor? I thought the reactor was suppose to make it that you didnt have to do kalk anymore?

This thread is extremely helpful...Excellent reads DragonSlayer.

I am in the process of setting up a 4x2x2 and am considering the C3001. Can you tell me if this device would be sufficient?

Living in Australia this is pretty much all we can buy. Would I need to get anything else? Also which pump would you recommend to feed the reactor?

Thanks

1502 Assembly

1502 Assembly

Great thread, especially Dragon_Slayer's posts, it influenced by decision to buy the 1502. Don't know if I'm just missing something, but my unit when assembled as pictured, has the tube that goes to the bottom of the chamber on the inlet assembly. Please refer to the following link for a picture that will visualize my problem:

http://www.marine-monsters.com/front/products/kalkreaktor_korallin7.html

The tube inside the chamber with the blue H2O arrow pointing down is actually on the inlet assembly, i.e., to the right of where it is shown in this picture. The only way to connect the pump to the proper tube is to have it hanging in the air somewhere with perhaps 6" of flex tubing. The shorter tube that's on the other side is welded on, so you can't just do a swich over.

Is this a manufacturering blooper, or am I putting it all wrong? I'm at work right now, I'll take a pic tonight and post if it's not resolved by then. My vendor is looking into it, as well.

Thanks in advance for your help.

if the short pipe with the cap and holes is attached to the side that goes to the CO2 and intake of the pump, it is correct.

if the tube cominig from the bottom of the reactor is attached to the CO2 and pumps intake the MFG screwed up on yours. i'd make someone replace it with the correct setup.

the idea is to have the reactor 'reverse flow' from bottom to top which gives better CO2 use and better Ca/Alk buffer IME.

KC, the mfg did reverse the tubes. However, with the help of a robogrip tool, the cap with holes came off, and it was an easy switch after that. Just inexperience on my part, thinking it was welded on.

Calibrating the reactor is another story ...

dragon-slayer i have a reef tank the same size as yours and going to buy a Korallin calcium reactor Korallin c-3002 could you tell me why you chose the Korallin c4002 ? RGibson

 

[dragon_slayer]

for the price difference between the two reactors i see no reason not to go with the larrger. i am also known to plumb more then one tank together.

After six months, the media on my C-4002 went down about 1". I guess I'm not supposed to wait till it disappears before replacing it?

I have 1502 with PM second chamber .Anybody know what should be rate for PH and KH from second chamber ?
Thanks

Geo Reactor

Geo Reactor

I use the Geo Reactor. I run the effluent rate about around 90ml a min. I have the effluent run into this cup (picture below).

What the cup does is put the effluent into the bottom of the cup, the drain is about 2" up from the bottom so the effluent goes from the bottom - up about 2" before draining. The cup holds a PH probe immersed in the effluent. I have a PH controller on the PH probe in the cup. This constantanly measures the PH of the eflfuent only and I can still count how much effluent I'm putting into the tank as the cup hangs on the top of the sump.

I set the low end of the controller to 6.70 and the high end to 6.8 PH levels. When the PH of the effluent raises above 6.8 the CO2 turns on. When the PH of the effluent drops below 6.7, it turns the CO2 off. So, the effluent PH is always between 6.7 and 6.8. Now, all I have to do is maintain the effluent rate to maintain the Ca in my tank. How fast the CO2 bubbles are put into the system does not matter. I never have to worry about something changing and the CO2 not turning off when it should and dropping the PH of my tank in error.

I also have a nielson reactor that I add Kalk nightly.

Ca 460
Kh 13.6
PH 8.15


Here's the link of the guy that sells these cups, they're at the bottom of the page .

Where Can I find a control valve to replace the original Koraline valve. The valve that I am missing attaches directly to the CO2 bottle. It controls the amount of CO2 flowing to the reactor and has a lock nut on its shaft for safety.

Thanks

dragon-slayer who many times a year do you need to clean the Korallin calcium reactor. RGibson

 

[dragon_slayer]

clean or replace media?

i have never had to clean mine, they dont get dirty (at least on the inside). media needs to be changed out compleatly and replaced with all new rather then just topping it off about once or twice per year.

Question on regulating

Question on regulating

Two to three weeks ago I set my new reactor up, set the bubble count to 10+/- per min. It will stay there a day or two or maybe only 30 min and then slows down to 6 or less. What is the problem and/or the fix?


Please advise.

 

[seeker]

If you're using a larger pump to feed the reactor and using a valve at the effluent end to limit the amount of effluent exiting the reactor it's possible that the pressure build up is changing the bubble count. Try to feed the reactor at the rate your discharging effluent.

Im using the pump that came with the reactor and have it set a 40 drops per the manufacture spec. The reactor ph is dancing around 6.9 to 7.1

I guess the next question would be due I increase the drip rate until I reach the CA reading that I want?

 

[dragon_slayer]

i dont think pressure in the reactor is your problem, it should never reach the pressure that the CO2 is regulated to without problems. my best guess is you have a bad (or cheap) regulator that isn't able to keep a steady output at a low setting, or you have a bad check valve on the CO2 line.

try boosting the CO2 working PSI to 25 and if you still have problems check the check valve.

The regulator came from Grainger for about $114 not to say that it can't be cheap.

When I set it up to 15 it will bubble like crazy. Should I turn it up and see if after a while it will settle down?
