So I finally got the GEO 818 Calcium Reactor On-Line. The Lab Neptune PH Probe Calibrated perfectly with 4.0 & 7.0 fluid.
I am using a Eheim compact 600 pump as my feed from the sump to the reactor. The Pan World PX40 on the reactor is a bit noisy so I will have to call the vendor to find out my options of an exchange.
If you are in need to find the CO2 Regulator Outlet Setup "Advanced" on the APEX please consider my input:
Fallback OFF
If pH2 > 06.60 Then ON
If pH2 < 06.55 Then OFF
If pH > 08.35 Then OFF
Defer 030:00 Then ON
So far I have the PH2 solid at 6.63. From my understanding CO2 starts to react with the media at 6.70 - 6.50 Anything below 6.50 brings the media to mush. 6.63 is a safe area to start with since I have SO much media, a full 3 gallons for only 4 frags in 270 gallons of water volume.
From what I noticed, since I have a large amount of media keeping this PH2 is very easy. I have the PA Regulator at a bubble at every 10 seconds and the working pressure very low around 3.5 psi to make the bubbles smaller.
This may change over time since the media is so new, but from the start the media is very "rich" and is easily bringing down the PH2.
By the way, the PA regulator is very expensive - but I am a first timer and I was able to lock in a PH2 in less than a few hours! Worth every penny plus a 3 year warranty included. I bought the 20lb CO2 tank and regulator with a special credit card which doubles the manufactures warranty. Just a pearl for those with the same coverage. (6 years coverage no out of pocket on the regulator alone!)
My PH is a bit low, but from my understanding the media is derived from Sodium Bicarbonate which lowers the PH for larger easier dosing with a lesser threat of killing fish. I will have to work on this to get my PH higher.
The drip is about 20ml's per minute which I will increase as I take further KH measurements. I would rather be under than over on my drip when first starting out. I don't want to unknowingly spike my KH.
You can also see I put the 36W Coralife Steralizer on-line - keeps the water crystal clear.
The stand area came out nice, I have a pretty decent roomy crawl space to access all the in sump equipment with out moving anything in the path.
Thats about it for now - I don't for see any further equipment additions. Just have to skin the stand which I got some good feed back from "postal" (Lee) as to where to find good affordable materials.
Thanks for following along, it has been a fun build - :wave:
