Setting up the PF601 on a PH controller

Question:

Hi Tony

I WAS SPEAKING TO STUART EARLIER ABOUT MY DELTEC PF601 REACTOR.HE GAVE ME YOUR EMAIL ADDRESS BECAUSE YOU NO MORE ABOUT RUNNING THE REACTOR THIS WAY THAN HIM AND YOU HAVE THE SAME REACTOR AS ME ON YOUR TANK VIA A PH CONTROLLER.I AM TRYING TO RUN MY REACTOR WITH A AQUATRONICA PH CONTROLLER I AM RUNNING THIS REACTOR WITH A PP6ML PUMPS AND ROWALITH C+ I HAVE 5 SPS CORALS IN MY TANK AT THE MOMENT AND I FIND MY AL/KH ARE PRETTY HIGH.COULD YOU TELL ME THE BEST WAY I SHOULD RUN THIS REACTOR VIA PH CONTROLLER AND HOW MUCH BUBBLES I SHOULD HAVE RUNNING THROW MY BUBBLE COUNTER PER A SECOND PLEASE. AND HOW I SHOULD SET THE PH IN THE REACTOR AND SHOULD I SET THE PH AT A MINUIM AND MAXIUM OR JUST TO STAY AT ONE LEVEL.

Answer:

Hi Jamie

I have the PF601s but its basically the same principle. I use a GHL computer but the settings should be the same. For the C+ i set the controller Ph for around 6.25 and set the Hysteresis at 0.3 so the Ph will drop to 6.22 before the CO2 shuts off and 6.28 when it kicks back in. You should be able to set the Aquatronica so the controller will switch the CO2 off between certain times. This way you can control the hours that the calcium reactor internal ph is low enough to liberate Ca/Alk based for your aquariums consumption.

I set my CO2 BPM to 120 a min but you may need this to be around 60- 90 on the 601, start at 30ml per min and watch the internal Ph of the controller. Keep increasing the BPM by an extra 5BPM and leave an hour after every adjustment. Once the Ph has reached the target set and the controller switches off the CO2 you have reached the correct BPM.

I run around 90ml a min through the 601s but the PP6ML should be o.k for the 601. You should leave this running 24/7 and let the controller bring down the Ph within the reactor at set times, during the day is best as this is when aquarium Ph is highest due to photosynthetic activity and less likely to be suppressed by the CO2 added top the reactor.

If Alk and Ca is high reduce the times that the controller is in active mode by a few hours each day and keep testing, the Alk should start to drop when you get the controller on times correct for your Ca/Alk consumption. To be honest you could get away with not running any CO2 through the reactor whilst the four corals grow out or you increase stocking levels as there is probably very little demand.

It may vary slightly from my advise above but will arrive at the same place.

If you have any further questions please don't hesitate

Kind regards Tony
