Low Ph at night how to fix?

[dandy7200]

Dan @ GreySeas Aquatics did the same thing to consistently boost his pH. He simply punched a tiny hole in the wall to the outside of his house and ran an airline tube from his skimmer to the outside.

 

 

The he got crazy and put his skimmer outside. 8.6 day 8.3 night

My Ph was reading 8.08 on a bad probe this morning so i am headed in the right direction. I am ordering a probe to see how if this reading can be correct but it is reading .48 higher since i extended the tubing outside so I am pretty happy.

Timely thread. Putting my sump in the utility closet with the hot water heater...now to find the a way to draw air from outside the space...

That's awesome! Definitely jumping up in the right direction.

If you were going to calibrate you must have the solution. Just stick it in the 7 or 10 and see if it is high or low and then you will know. Also, check this out. I think this would solve all your problems if you don't like venting outside.

bankyf any idea on the media they are using... ??

Only thing I have found online so far is monoethanolamine used in submarines to "scrub" CO2. But from what I have read it is pretty unstable, quite different from MCU Research media.

Yes, I do. I am almost positive that it is the same media used as the CO2 scrubber in scuba rebreathers. Virgina Scuba in Manassas has the media in stock. Not sure on the cost. Some divers refer to it as Kitty Litter as I believe that is the look and consistency. Virginia Scuba sells Dive Rite rebreathers which uses a canister with the media in it, some of the other brands of rebreathers just use a bulk media that you use the refill the canister.

Great! I found this article: http://glassbox-design.com/2009/soda-lime-...s-mcu-research/ and someone posted that you can get 5lb of media for about $54 and spend $34 on a canister from RBS. So for about the same price you get quite a bit more. I wonder how much is it to buy the media locally. How much do they charge at the scuba place? Anyone knows?

 

I also suffer from low pH because my sump and skimmer are located besides the furnace and gas water heater in a room with no ventilation.

I would need to run about 25+ ft of tubing to get outside the house and drill a bunch of holes.

 

I am going to try to run a "shorter" (10ft) tube to the garage and see if I can see a significant increase in the pH.

 

The CO2 scrubber seems an elegant solution though.

HERE they sell 2.2lbs of sodalime media for $16 plus $11 ground shipping.

SOFNOLIME is another option. At scuba.com they sell 44 lbs for $179. That $4/lb. This is something that might be available locally.
