Planeden Posted October 31, 2013 Share Posted October 31, 2013 more or less a guess, but high pressure may increase gas exchange. the air is effectively pushing on the water harder so more air gets in when the water is agitated. like a low pressure day is people leaving the office at quiting time. high pressure day would be people leaving the office during a fire. that said, storms are lower barometric pressure, not higher. but with our relatively small changes in barometric pressure, i'm not sure this would have a measurable effect (this is a hunch built on a premise that may or may not be true).

victoly Posted October 31, 2013 Author Share Posted October 31, 2013 solid logic. I'll allow it. Link to comment Share on other sites More sharing options...
jestep Posted October 31, 2013 Share Posted October 31, 2013 Mine stayed the same. Did a water change even and looks the same as the past 3 days. Link to comment Share on other sites More sharing options...
victoly Posted November 19, 2013 Author Share Posted November 19, 2013 The data is in, and IMO there is a pretty good correlation. Link to comment Share on other sites More sharing options...
Planeden Posted November 19, 2013 Share Posted November 19, 2013 obviously you need to tear up some of your door and window seals to stabilize the CO2 and keep your tank at a constant temp. Link to comment Share on other sites More sharing options...

victoly Posted November 20, 2013 Author Share Posted November 20, 2013 so i hooked up a CO2 scrubber and my pH totally leveled out. it will be interesting to see how it behaves throughout the course of the photoperiod. Link to comment Share on other sites More sharing options...

FarmerTy Posted November 20, 2013 Share Posted November 20, 2013 Gonna be experimenting with the same thing myself. Hopefully the CO2 scrubber will alleviate my pH woes. Link to comment Share on other sites More sharing options...
Gig 'em @ NDstructible Posted November 20, 2013 Share Posted November 20, 2013 I was just going to suggest adding an air filter to your protein skimmer air intake. We use canister filters in our ambient air monitoring stations to hook up to our criteria pollution analyzers and calibrators. I have air filter canisters on the back of my air source I use to audit said analyzers to create "zero air" to run through the analyzers to see where their baseline is in case they need to be re-calibrated. Annnnnywaaay, I use a combination of puracol, purafil, and drierite (Although drierite would be pretty useless in this application). What filter media do you have in that canister?? And what analyzer did you use to monitor the CO2 levels in your house? I can get a Teledyne API CO2 analyzer to continuously monitor the levels in your house! I would think that the AC not turning on is the root cause of the spiked CO2 levels and therefore the lower pH levels. When the AC turns on it puts your house under positive pressure and forces air out of the cracks and leaks in the house, which then draws in ambient air replacing some of the CO2. Also, if your heater came on for the first time during the cool weather, I would think the burning of gas in the heater would put higher levels of CO2 in your house, plus the build up of dust in the ducts since last winter would be burned the first time your heater came on, releasing even more CO2 into the internal atmosphere of your home. That would help explain an even larger spike in CO2 than normal. Link to comment Share on other sites More sharing options...
victoly Posted November 20, 2013 Author Share Posted November 20, 2013 I used a telaire co2 meter. The media is good old veterinary grade soda lime. Link to comment Share on other sites More sharing options...

victoly Posted November 21, 2013 Author Share Posted November 21, 2013 and this, ladies and gentlemen, is what a CO2 scrubber can do for you. Link to comment Share on other sites More sharing options...
FarmerTy Posted November 21, 2013 Share Posted November 21, 2013 My results were not as sexy. My DIY CO2 scrubber Results Last peak on the 21st was when the CO2 scrubber was added. The two peaks before that were from when I opened all doors and windows and left them that way for the day. Days before that were justn normal days of low pH. Nothing juicy or exciting here. I guess we don't breathe as much in our house as much as Victoly does. I'll let it run for the week but I knew going in it might not have as much of an effect on my house since it's an older house (meaning leaky) and much of my pH suppression going on in my tank is from the CaRX. Now to address the CaRX output and minimize the CO2 being added to my system through that setup. Link to comment Share on other sites More sharing options...
victoly Posted November 21, 2013 Author Share Posted November 21, 2013 have you considered adding a second chamber to your CaRX to pump the effluent through that's filled with CaCO3? Link to comment Share on other sites More sharing options...
FarmerTy Posted November 21, 2013 Share Posted November 21, 2013 Adding the 2nd chamber and also rerouting the effluent to the skimmer section are the two options I was going to try. I'm sure there is some tweaking I could do to run my reactor more efficiently without just dumping tons of CO2 in it but I hadn't had a chance to experiment with that yet. I currently run at 6.35 pH for the effluent of the reactor which is super low compared to most. But it gets me my perfect 7.6 dKh so hard to argue with result.

victoly Posted November 21, 2013 Author Share Posted November 21, 2013 Also, not sure how you had your setup, but is the air being pulled up through the soda lime or just into the same chamber? Link to comment Share on other sites More sharing options...
FarmerTy Posted November 21, 2013 Share Posted November 21, 2013 Holes at the bottom of the container pulled through the soda lime and exit at the top tube. The bottom has been lifted off the ground to not restrict air flow with the holes being on the bottom. Link to comment Share on other sites More sharing options...

+olaggie01 Posted November 22, 2013 Share Posted November 22, 2013 I got my CO2 scubber online last night. Let me check the charts and see how it did overnight. I don't believe it bottomed out as before but I'll see how the chart looks. Link to comment Share on other sites More sharing options...
FarmerTy Posted November 23, 2013 Share Posted November 23, 2013 I take it back. Before opening windows and running CO2 scrubber, pH maximum was at most, 7.80. Today it hit 7.96... color me impressed. Combine that with running a 2nd chamber for the CaRX soon and I might be able to achieve 8.20-8.30 perhaps.
