What PH do you keep in your Calc reactor?

[Ruge13]

Just curious what others are doing? If I tune the reactor to get to 6.3/6.2 the effluent hose gets clogged and the reactor drops quick and shuts down. If I bleed the effluent at a rate that does not clog I cannot get below 1.45. While that does yield an effluent that is higher in calcium than my tank water, it is not enough to keep up.

I use regular ARM media.

IME regular ARM turns to mush pretty easily if the PH is below 6.5-6.6 ish.

I run the ARM course and keep my controller set to keep the PH at 6.6-6.8 and find that to be much less trouble. .

^ I run the same as John , 6.6 - 6.8

I run the large media, and run it a little lower 5.9-6. I might try raising it a little, but was having trouble when I switched from the small media to the large.

Obviously I meant 6.45 not 1.45 above. John the break point is easily noticed in mine with regular arm. @6.4 no problems. @6.3 and my chamber fogs out, bad things man... bad things. I have my controller set to shut it own at 6.2 but with the solenoid settings and the steady stream (not drip) out of the reactor I have now I don't see below 6.4.

IME it always seemed to turn to mush at a little higher PH, but the probe I was using at the time may have been off a bit???

Either way, I like the ARM course much better.

Good to know about coarse.

No you are wrong! I'm sure my PH probe is not exactly calibrated. There has to be some variance to allow for +/.10 maybe.

Mine may have been off by more than that Figure a probe that's a few yrs old, and was calibrated at 7.01 and 10.01, while controlling in the 6's range.
