ORP Probe in AIO

[Dro]

hello all,

i was hoping to get some guidance. i have an IceCap AIO 45 gallon. I’m going crazy trying to find a place to put my ORP and pH probe. the tank has a 5 chamber area in the back. the set up right now looks like this: [media basket] -> [skimmer] -> [return pump] <- [UV sterilizer+heater] <- [media basket]. at first i had my pH and ORP probes in the return chamber but that’s where i’m planning to dose and it’s so small that i figured it wouldn’t work out. so i decided to move my ORP probe next to the skimmer but then i realized about the micro bubbles and at this point im debating wether to put it in the DT or idk. right now i have it placed in the baffle between the skimmer and the return pump but im not sure if that’s a good idea and if im going to get accurate readings. any suggestions?

Thank you!!

Maybe dose into the display and free up that chamber? I manually dose tanks with ESV 2 part and ARF and I pour it into the DT in a high flow area. I've done it that way for years and it works fine. Would probably also be fine dosing into the return chamber. I have an NPS tank that I dose phyto into the return chamber every hour 24/7.

I currently have all my GHL probes in the return pump section.
Pros:
- No bubbles
- No light which would accelerate growth of unwanted matter on the probes

Cons:
- Temperature probe after the heater kind of sucks
- Hard to reach spot
- If I have to stop my return pump the water flowing back can still cause bubbles which accumulate on the probes. I give them a little shake afterwards and they are reading fine again.

There is always something. No matter where you put them.

Put the probes in the return and dose into the tank.
I dose into the aio but could easily set it up to dose in the tank.

I have my temp probe attached to the return in the tank.

Thank You all for the responses. i’ll put them back in the return pump and dose in the DT as @EnterName suggested
