Official: Masterflex Calcium Reactor Setup Thread

I have this over for sale FS: masterflex 7523-70. I repurpose the head so it's only the masterflex base is for sale.

oops, wrong thread

 

[hkgar]

For my reactor choices im looking into getting one of these two types.
http://www.aquacave.com/my-reef-creations-mrc-cr-2-calcium-reactor.html
or
http://www.aquacave.com/super-reef-octopus-3000-d-calcium-reactor.html
My system volume is around 250g but wanted to get a oversized one for future expansion and i would rather have more then enough then not enough.

I have this one:

and am very pleased with it.

$250 for that is too low of price, someone needs to grab that soon.

I did go ahead and go with this one after doing some research. If you have any setup advice or anything important you know you can tell me about the reactor will you PM me?

Ok so this is what i have gotten so far

masterflex 7523-70- thanks for the great deal scuzy!
Supper Reef Octopus SRO 5000 calcium reactor
carbon doser c02 reg.

opinions please this is what i still need
easy load head
pinpoint ph controller
10lb c02 cylinder
all correct fittings to connect the masterflex pump properly
two little fishes reborn calc. media
zeo mag magnesium granulate
more patience

 

[hkgar]

Do you have an Apex controller? Or similar?

What are you dosing now?

This link will help you switch over from dosing to reactor

http://reef.diesyst.com/reactor/reactor.html

5Lb cylinder may be enough. That is all I have and it last at least 6 months.

I use ARM coarse media and do not add mag. If mag is needed I dose Randy's recipe.

I have a reefkeeper lite and right now im dosing 80ml/day calc. and 70ml/day alk. ive been seeing more and more mag. consumption so now im dosing that right now im at 10ml/day
All BRS supplements on a bubble magus doser

Can you use the reekeeper to program the CO2 regulator to turn off at 6.3 PH. That is all you need a controller to do. If the RKL can do that you do not need the pinpoint.

Don't see a co2 regulator on that list so you will need one as well. Regulator will run you from dirt cheap to expensive but having a nice masterflex with a cheap reg should be a crime

He listed the Carbon Doser reg

i have the carbon doser c02 reg.

Ahh ok didn't see that. Although no comment on where that falls in the quality scale since it tends to rile up some people around here.

I can and was going to use both just incase one failed i would have a back up?
Maybe the pinpoint off at 6.3 and the RK off at 6.2 if the pinpoint failed?

Ive heard more good then bad so i will give this a try.

How are you going to connect 1 ph probe to 2 devices?

on the returning side, so 2 devices 2 ph probes
With as much as ive been hearing about probes and controllers failing good quality and bad im spending good money on this setup and want it as safe and stable as possible i cant have my system crash.

Good luck with that. Ph probes are notorious for drifting. So unless you are calibrating consistently, 1 or the other will drift. So your redundant safety may not be hat redundant after all and cause more issues.

I don't use a pH controller or my Apex to control the effluent. I adjust the Masterflex and the reg to produce effluent at the rate the tank is consuming and I use the pH probe (that I calibrate once a month) as a safety stop. But if your reg n pump are reliable, there is very little danger of dumping too strong of effluent into the system.

E.g. My Masterflex is set to 10ml/min (I think) and my reg is set to produce a pH of 6.9-7 in my CaRx. This does not mean my Apex shuts off the solenoid when it hits 6.9. Solenoid is always open and effluent flow is constant.

Apex is set to shut off the solenoid if CaRx drops below 6.7 and shut off the Masterflex if tank ph drops below 7.8.

So if pH probe drift high, no big deal, effluent stays the same because pH in the CaRx stays the same since my solenoid is always open. If you set it to shut off at 6.9 and your probe drifts up, the controller will keep the solenoid open because it thinks it's still high when in fact it's dipping below set point.

Then you should take a look at building a custom CO2 dual stage reg. For what you paid, you could have gotten a very nice industrial reg that will be very very reliable.

I've not heard ANYTHING bad about a reg built that way.
