Advice? ph issues

Couple weeks ago i moved my apex from my system upstairs in my house down to my utility room where the sump is for the new system and immediately the dashboard read in the low 7, when it had been a steady 8.2 before. Ever since the move the ph has slowly been dropping. I opened the window in my utility room for a couple hours over the weekend and got it up to 7.4 but dropped back down to 7 within 24 hours. Any suggestions of things to try, I didn't move the probe in water, just took it from one tank straight to the other. Could it have lost calibration?

 

Unfortunately it'll have to wait till this weekend since I work over the road. For some reason I've always had trouble trying to calibrate. When I dip the probe intothe different solutions the numbers on the apex barely change.

 

I try to wipe the probe. I had it sit for the better of 15 minutes once and the numbers never moved. I had the brs video going at the same time to make sure I was doing it right.

 

I'm really hoping it is the probe. When I test with api it's right at 8.2. So that's why I'm confused. Hopefully I can calibrate this weekend. Thanks

 

I have 2 room attached to each other in my garage with a 3 x 4 hole between the two. One room is directly for equipment and the other has my furnace and such. That was I could have air exchange between the 2 when the furnace runs. I run geothermal heat.

I did some look and seen brs sells some absorbing media but am unsure what to put it in so I can hook it to my skimmer. Any suggestions?

 

Yeah I found some co2 absorbing media, I just got make sure the canister I have is the right one. If I still have issues after calibration I'm going that route, my curious question is how long of a hose can be hooked to a skimmer before it causes issue?

 

Did you put any sort of filter on the end to keep bugs and such out?

 

Probe is only a few months old. So I'm not really thinking it went bad already. Actually leaning more towards co2 in the room. Going to try an outside line this weekend

 

I have no clue what the actual issue is. Since I have conflicting tests results, but all I hear is api tests being junk I'm going to calibrate probe first. Which I have stated many times. So if I calibrate the probe and nothing changes it could be one of many issues that have been suggested to try and change.

 

Running a line from my skimmer has been suggested to me before as just a good idea, I've just never wanted to do it because I didn't want to put a hole thru the wall.
