ph in reactor ques.

[SlamaJama]

got my reactor up and running,
im about 30-35 b/m of Co2, and i cant get my ph water FROM the reactor to go lower than 7.5...tryd increasing flow but still wont lower. my target ph should be from 6.6-6.9?
thxs,
mike

Mike what is the effluent rate? You need to decrease the flow throught the reactor and/or increase co2 to get a lower effluent PH.

and ive been doing the opposite...geezz...ill post my test in bout 2 hrs after adjustment, thxs rich.

I dont know if 2 hours is enough. I have measured mine after a few hours and then again 12 hours later and it drops a little more. Do you have a dual chamber? If so you want to measure the effluent from the first chamber if you can.

 

[SlamaJama]

naa..single chamber...i just chked went down to 7.1 from 7.5...so at least im in the rite direction..lol

Make sure you do it slowly, don't mess with the bubble count too much, just adjust the flow of the effulent (like Rich said, ).

Yeah best advice is do it slowly. You dont want it to get too low. Once its set you pretty much just leave it alone until your co2 or media run out. I check mine every so often but it hasnt fluctuated at all since I set it.
