Long story on my CaRx but I overpressurized and broke it. I was also struggling to keep pH when running it, so for now it is on the shelf.Thank You Bro, but I think that @Biggestfish is in the lead with all his corals branching , I don’t know how this contest is going to be judged !
I do have a couple of question’s for you because I am also running a CaRX !
What is your PH at ?
And are you doing anything to help raise it ?
My PH is at max 8 in the day and drops to 7.6 at night. The best readings that I have from manually testing because I don’t have any sophisticated technology (Lol) but it really hovers around 7.8 to 7.6 and I don’t like those numbers !
I run a outside air line directly to the skimmer pump and the effluent line to the head of the skimmer pump. I have a refugium running 16 hours. My next move is to probably dose Kalkwasser, Ugh, dosing was the reason why I switched over to the CaRX . Maybe you can shed some light on my situation
If you are getting 7.6 pH on tank water, @Randy Holmes-Farley would suggest that to be almost impossible; your probe needs to be calibrated or replaced. Likely more like 7.8 - 8.15. Plenty of room for improvement.
I was also running a CO2 scrubber, but my skimmer wasn't big enough to make much difference. Since setting up and dialing in a Kalk stirrer, managing pH is so easy, I am not certain what will make me go back to anything else. My 2-part dosing -- while still alot -- is half what is was originally. (1/2 liter per day versus 1/4 liter now).
If you have APEX AND ample space for a Kalk reservoir/stirrer, PM me and I can walk you though my set up. I am all about low maintenance reliability and this fits.
