I have noticed the last two times I've cleaned my algae scrubber that my ORP drops from around 320-340 to about 240-250 right after I remove the algae from my scrubber. Just an observation, the tank is less then a year old and I've only started trending my ORP values this last month. It's picks back up in a few days and the tank is looking good, so I wasn't too concerned. My understanding of ORP is weak at best, something about oxidizers (O2&O3) compared to reducers(dead organic material). Can anyone help explain why my ORP is dropping during this time?
