Why wont my Calcium reactor work correctly ? HELP PLEASE

Do I read that correctly - you can not adjust the low pressure side of the reg? What do your two pressure guages read?

This reg sucks Im going to buy a carbon doser when I get the chance

Does it not allow you to regulate the 2nd stage Psi? if so sounds like it just comes preset controlled with a diaphragm mechanism that has a set psi

Correct

So my ALK has been holding steady at 8.1 since last Friday with the reactor running stand alone .

Thank you everyone for the help ! I really appreciate it !

You read correctly. That regulator has a fixed low pressure rating. I don’t really understand the point of the gauge then if you can’t manipulate it

Regulator quality is important. The lower quality regulator you use, the more of a headache it will be to tune your reactor and keep it tuned. The inexpensive single stage units will naturally increase their output as the tank pressure drops over time.

Check out the Alanle regulators... he built me one. Way better than carbon doser

here's mine:

Large Build - BDare's 210 Mixed Reef

Hello all, Long time R2R lurker here. Been keeping aquariums my whole life and reef tanks since about 2005. Six years ago I shut down a 120 and I've been missing it ever since. The bug has got me and now I'm planning a new 210 gallon tank. Equipment Tank - 210 Gallon Planet Aquaruims 72L x...

So Im right back to square one with this point of sale reactor . I bought an Alan Lee dual stage regulator he built for me . I have not been able to yet again get a high effluent and keep my Alkalinity stable at all .
I am running the solenoid open 24/7 now . I have 40ml per minute drip . I have been keeping the reactor PH at 6.5 . Over the weekend I removed a bunch of media and now have the reactor at like 1/3 full .

Im back to dosing alk right now since my reactor is doing nothing as usual . Im so close to just getting rid of it . If I didnt have $700+ into this dang thing it would be in the trash .

40 ml per hour or minute?

Per minute I meant .

How many bubbles per minute? What the dKh of the effluent?

Have you measured the alkalinity of the effluent?

Why? You’re running a relatively small GEO 612... removing that much media doesn’t leave much to support your 120 gallon tank heavily stocked with SPS.

C. Eymann · Nov 25, 2019

Again, are you absolutely sure nothing is obstructing the recirculating pump? it working? Is it shoving water through the media like it should? Like I said from the start, your symptoms tell me it isn't for some reason, if your probe is accurate that is.

gilman · Nov 25, 2019

Effluent is 12.8dkh

jda · Nov 25, 2019

How many bubbles per minute is that?

right now anywhere from a bubble every 8 seconds to every 22 and inbetween I was counting

12dkh seems low for 6.5 in the reactor. I also think there's something g wrong with the variable bubble counts. What pressure is the regulator running at? Have you tried recalibrating the probe? How did you calibrate?
