Please do. For scientific purposes haha.. Honestly don't know how accurate it is. My api test never showed me a reading above 8.1. My seneye tracked along those lines and then bumped up when I upgraded skimmer in tables. To now it just appears to be stick around 8.3. Im chalking the last week up to wierd stuff happening in water column but seems to have settled down in last cpl days. I need to get a probe or something reliable to cross refference to from time to time especially when I change seneye slides.My pH reads low always. I stopped trying to solve it - corals are doing fine. I have probe I should plug in to cross reference though...
