Ph issues

[jimbosreef]

Hello all,
for a bit now ive been monitoring my ph and ive noticed it never gets above 8. so to trouble shoot this i opened windows in the room of the tank and within the 24hr period the ph reached above 8. so my next step is to run either a Co2 scrubber or start dosing kalk. my question to you all is. what is the more reliable and more consistent change to make to help keep this ph around 8 or above?

this is on a waterbox 7225, running skimmer, 2 mp40s and a gyre. i have alot of surface agitation. also a sps dominant system. i do dose 2 part as well



TIA

CO2 scrubber will usually have a larger effect, although both are fighting against tank top aeration. Kalk is only useful if you have substantial daily alk demand.

CO2 scrubber media will be more expensive.

Air line from skimmer inlet to outside is the cheapest option, if you can wrangle that.

Run a air line outside for the skimmer.

airline outside i dont believe will be a possibility. that was an option i had already thought of

My SPS tank ran for over 2.5 years with a daily pH swing of 7.6 - 7.9. Out of curiosity I added a skimmer and ran an outside airline to the intake and now my pH is 8.0 - 8.3 daily. I'm getting faster growth from my acros but other than that no noticeable difference. If your looking for faster growth then it's worth it IMO. If your not interested in faster growth I'm not sure there any other benefits to make chasing pH worth the effort.

I agree with not chasing pH.
However, if you go with a CO2 scrubber. If you get media from other than a “reef” store, it’s pretty reasonable.
For example, I get a 38 pound bucket from Med Vet international for $98. It will last me probably a year. If you got that much from a reef store you’d be paying about $500-600
