Mother of all Calicium Reactors 5 Stage Marinetech

[littlesilvermax]

That is what I need.

I have a 6 inch reactor that I run with a pcx-30 and it is 28 inches tall. My bubble count is about 200 bubbles/min and I recirculate all of my CO2. My ph is 6.3 and the effluent is at 68 dkh (checked 3 times)!

Still has a hard time keeping up with my 3 lbs of SPS growth per month!!!!!

That sounds like an impresive tank .

It is coming along.

I am re-writing the tank diary in a shorter version here.

How long has it been on the market for, and how much does it cost?

Just opened one up. Mad AWESOME!

OK this looks like a great reactor. However there is a problem with the concept of stage 5, de-gassing the effluent to remove CO2.

If you de-gas the effluent before it leaves the reactor, the pH rises, the Calcium and Carbonate ions become less soluble and would be expected to precipitate out during stage 5.

Doesn't it more sense to do a de-gassing after the effluent has mixed back in with tank water?

Do these guys have a website?

No, i dont think it makes more sense .

Whats the difference if your degassing before and slightly increasing PH before entry, or just dropping it in the sump or tank with a high oxygen, high PH ?

Either way some precipitation occurs...just in a different spot.
The whole point is what your left with afterwards and as a whole.

Actually there is a big difference. De-gassing raises the pH of the solution you are de-gassing. Raising the pH of the effluent solution will decrease the solubility of the Calcium and Carbonate ions down to the same solubility as in your tankwater, so most of the CaCO3 you have dissolved in the reactor will promptly precipitate out. Waiting to mix it with tank water and then de-gassing this mixture will result in a lot less precipitation, because the effluent has been diluted by tank water, and the concentration product of Calcium and Carbonate ions will be a lot less than in the straight effluent, so less will precipitate out.

I think your missing the point.....


What im saying is, no reactor effluent is diluted/mixed when it hits the tank water, therefore your precipitation is occuring when it hits the tank water, rather than in the air chamber.

So, pick a precipitation point and be happy with it, because it doesnt matter where it happens...it happens.
