Question

[Mydoghasfleas]

Looking at your products, and have a few questions. For a 240g sps reef. I have been looking at the cr612x2 dual chamber reactor. Would this be appropriate, or would the cr624 with UMC second chamber be the way to go?

Hello and thank you for your consideration. Since you are going SPS with that volume I would advise the CR624 with UMC415. We are now building a 2017 model with Sicce Syncra 3.0 as the circulating pump. This has made the reactor more efficient. Also this model now comes with needle effluent valve and high grade check valve for C02 input. LMK if you have any questions.

Please disregard what I wrote above I had somebody else's tank in my mind while writing you very sorry for that

You would actually be better off with the CR 618 and SMC 415 in combination this would be a perfect duo for your system.

Thanks for the response. A few follow up questions. What is the difference between SMC and UMC? Also, why the 618 over 624? Would the smc 415 be a good fit for either/or?

 

[geo]

The UMC and SMC are physically the same. The fittings are actually different. The SMC fittings are push to connect so that they match the calcium reactors as a secondary media chamber. UMC or Universal Media Chamber is designed for filtration with use of media such as carbon or GFO.

The CR618 is the appropriate reactor for your size system. The CR624 would also work but is definitely overkill for your size system. I would recommend the SMC415 for both reactors.

Thanks for the help, much appreciated. One last question, what media combo do you recommend for the two stages?

I have scrolled through this thread:

But wanted to see if this combo was still a recommendation.

 

[geo]

Yes, this combination works very well. In main reactor chamber use 90% TLF Reborn and mix in 10% Remag. Secondary chamber SMC 100% Carib Sea ARM.

Hi, was trying to assemble some equipment today. Decided it would be best to ask a few questions before proceeding further than I already have.

This is what I have so far:

 

[Mydoghasfleas]

Now my question is, should the white line have gone there?

I have this black 1/4 PVC, that should go to the CO2?

 

[Mydoghasfleas]

And if this is a correct configuration, how would you recommend attaching the white line to the pump?

Best to refer to the manifold instructions. The harness was already assembled for you. You were almost there

That's a lot easier than the instructions I was trying to use! Is it possible to get the white hose out of that fitting?

 

[geo]

Those are all push to connect fittings. So there is a collar on the fitting which should be black. First with one hand push the white line in further while holding the black collar in place with your other hand. Keep pressure and hold in place the black collar and at the same time pull out the white line in the opposite direction. It takes some practice and also hard to explain. LMK

It was a bit tough to remove, so improvised a bit. I removed the fitting where the effluent should be flowing from (left the white hose here), and switched it with where the pump fitting was.

 

[Mydoghasfleas]

So, just to make sure I don't make another bone headed mistake...

Effluent should enter here now, on the top, on the second chamber...



And exit here, with the blue hose with the control knob.

 

[Mydoghasfleas]

And I will just use the extra blue hose I have now instead of the white hose for the C02.

Edit:

I think I got it, thanks for the help!

Actually the input on the secondary chamber is at the bottom and output at top. The CO2 naturally wants to go up so you get better saturation from bottom to top flow.
