CO2 scrubber

[Frank Infanti]

Like most I'm having a hard time maintaining a 8.0 PH during the winter months. Anyone have experience using a CO2 scrubber in the inlet part of the skimmer? Would having fresh air feeding the skimmer inlet yield the same result?

I use one it cost about 100 dollars a month to run. keeps PH at 8.3 and 8.1 at night

I get a .2 average increase just from a fresh air intake into my skimmer. C02 in house can get up to 1000-1200ppm (3 times outside air) which drives the PH down quite a bit.

Was considering a scrubber but air intake is way cheaper if you can do it.

I use the 350 Twolittle fishes and the stuff Ray sells me at Reef supplies

I change out every 3 weeks.

[Bugger]

Yeah the 550. It lasts about 3 weeks like yours

You can vastly reduce the costs as Myka has noted by buying soda lime (many different trade names) through a scuba supply store. It's used for re-breathers to scrub CO2.

the air-inlet for the reactor is still feeding from outside a window

saw a video on BRS TV,,, about routing the intake line for the CO2 scrubbing media scrubber to the top of the collection cup on the protein skimmer..

This way air passed into the scrubber media is already low in CO2, and has to do less work...
(your media will last much much longer, and your pH will be higher !!

just started it a few days ago. and my pH mark is 2 hours ahead of the previous day.

give it a try !
