Question on Cal.reactor W/AC JR.

[robertifly]

I've got a Austin Ocean 2 stage cal. reactor, and ac jr. to control the tank. My question is the initial parameters on the controller for co2 are: if ph >8.45 then co2 on, if ph <8.35 then co2 off. My co2 hasn't been on since if hooked it to the Jr. Are these correct param. for a cal. reactor or some other form of co2 injection system? What should they be to increase the water cal. it is consistently in the 380 range and would like 400 - 450.Thanks for some help with it.

anyone?

 

[chadfarmer]

those are just base parameters

start at 6.7 - 7.0

if that isnt enoff than go 6.5 to 6.7

also depends on the media you are using

 

[turtleman9100]

where is your ph probe? tank or cr?

agree put pH probe in ca reactor, then set parm. to <6.35 off and >6.40 on

 

[robertifly]

Thanks for the responses, yes the controller probe is in the reactor and I have another in the return side of the sump. The media is the large style, not sure brand maybe A.R.M.?

 

[robertifly]

Thx, I now have controller set: >6.40 on and <6.35 off and bubble rate is 18 - 20 per min.

 

[1badbrd]

bubble rate should matter anymore since you have the controller. I think the bubble rate is more to controll the pH manually if you did not have the controller.

 

[robertifly]

you're not saying I should open the valve more now that the controller is working are you? hmmm, maybe ok I just don't experience and don't know, the thing may work better with the co2 opened up more.

 

[chadfarmer]

what model do you have of calcium reactor?

how many bubbles per minute?

i have mine were my co2 bearly shuts off and runs most of the time

the controller is a fail safe

 

[robertifly]

It is an Austin Oceans dual chamber cal. reactor and the bubble count is 18 - 20 min.

i guess having a bubble count would be a second safety step incase the solinoid brakes, but.... bubble count is not needed with the controller maintaining your pH in the reactor. I just didnt waste the time to count my bubbles but chadfarmer is right if you can control the bubbles so its more consistent with maintaining your pH then just even better. I have a cheap reactor so the bubble count suck and isnt reliable
