Hi Folks,
Been swearing I was gonna do it for a long time. ESV buckets are stacked to the ceiling already, but the end of that is in sight. The ACR is here, no longer leaking, and running on my 300G frag system. And Lord knows I have the time to figure it out these days.
Device: 8" stacked with about 25lbs of coral skeleton and one jug of A.R.M coarse. 3lbs of Reborn Magnesium.
The ACR setup has no reliance on bubble counting or PH probes. The only "controls" are frequency and amount of effluent dosing. Simply set how many seconds of delay, and how many seconds the valve stays open. It is "said to" run at about 6.8 ph. Pressure to the valve control module is 8 psi.
I've been trying to measure the effluent DKH. I believe it is >60dkh. I stopped at 4ml reagent on a full strength sample without color change and 2ml on a 4:1 diluted sample. Skittish about wasting more reagent as I only have one box left and I care more about system dkh anyway -- which I keep around 8.3 +-.
Question 1:
Is >60dkh effluent scary to anyone? Is it OK that I don't really know how high my effluent dkh really is? Is there a point where I risk the media turning to mush?
Question 2:
Should I use another test kit for effluent testing? Hanna goes to 20. Dilute it 1:4, test, multiply result by 4?
Question 3:
Should I shut off the APEX DOS all together tonight?
APEX doses 110ml of ALK overnight and 110 Ca during the day. Right now, the ACR is dumping ~15ml of effluent every 200 seconds. It has been running for about 4 hours. ALK has been steady at 8 over that time period (during peak photoperiod). System consumes/swings about .8 dkh each day. (Thus, a CaRx)
Question 4:
Should I test the PH of the effluent? If so, what is healthy range to expect?
Question 5:
I have a lot of named and unnamed acropora, so I will be paying attention. I will listen to suggestions of WHAT I should be paying MOST attention to.
Tagging a couple folks I've seen discussing CaRX with frequency and clarity, but feel free to tag in anyone else you think I can learn from. @jda @ca1ore
Many thanks all,
scott
