Phosphate is at .03 ppm (hanna ulr)Before we jump into the deep end and conclude that a low ph of 7.8 was the leading cause of coral death, can you please share water parameters? What were the big three and more importantly, N&P? If your N&P bottomed out, I suspect that they were likely suspects vs “low” ph.
That is very interesting— your params look like fine to me. Was there a spike in Alk? I’ve lost SPS due to Alk spike and/or zero nutrients but not low pH.Phosphate is at .03 ppm (hanna ulr)
Nitrates at 23.1ppm (hanna)
Alk at 9dkh
Calcium at 445 neptune trident
Magnesium at 1350
Alk never over 9.1 but sometimes at night it will hit around 8.8_ 8.5 the lowest I have changed over night dosing to help with that drop it's been closer to 8.8That is very interesting— your params look like fine to me.

Also what do you use to dose alk cal mag?That is very interesting— your params look like fine to me. Was there a spike in Alk? I’ve lost SPS due to Alk spike and/or zero nutrients but not low pH.
CaRx — super low maintenance! Yes, pH takes a small hit hence I counter-balance using recirculating CO2 scrubbing. Mag is manually dosed twice/year. I’ll put Mg media next time I top off CaRx mediaAlso what do you use to dose alk cal mag?
Is Carx is expensive to set up?CaRx — super low maintenance! Yes, pH takes a small hit hence I counter-balance using recirculating CO2 scrubbing. Mag is manually dosed twice/year. I’ll put Mg media next time I top off CaRx media
Yes, but cost of running is low.Is Carx is expensive to set up?
I have a GEO CaRx — when coupled with a decent regulator and reliable peristaltic pump, things are super consistent and with little/no touch - for months! Just need to put more media — depending on your SPS/Coralline algae consumption — once a year maybe?Is Carx is expensive to set up?
Have you tried recirculating CO2 scrubber? It will definitely boost your pH. You can also try sucking in outside air or vent your house, but only get marginal results. Dripping Kalk will also help since its pH is 12.4 but it will raise Alk and Ca.I struggle with keeping Ph above 8, its usually 7.7-7.8, U run my alk at 9ish, My corals dont seem to care although I think higher PH will give me better growth
Doesn't it requir a co2 tankI have a GEO CaRx — when coupled with a decent regulator and reliable peristaltic pump, things are super consistent and with little/no touch - for months! Just need to put more media — depending on your SPS/Coralline algae consumption — once a year maybe?
Yes, high initial upfront cost but cheaper long term. The huge benefit for me was the maintenance — I suppose my time might worth more than mixing jugs of 2-part and/or kalk. Been there, done that — ain’t doing that no more! lol
Yes. Sometimes you can find them used also. Or Amazon.Doesn't it requir a co2 tank
CO2 canister is "cheap" -- I think $18'ish(?) that should last me a year. I get mine from a local beer brewer when I swap out beer for my kegerator, which is almost every month/two! lolYes. Sometimes you can find them used also. Or Amazon.
Can you send me a picture of complete set up? What kind of pump is used to pump the waterCO2 canister is "cheap" -- I think $18'ish(?) that should last me a year. I get mine from a local beer brewer when I swap out beer for my kegerator, which is almost every month/two! lol
I use the kamoer parastalic pump. Solid.Can you send me a picture of complete set up? What kind of pump is used to pump the water
