Get outside air into tank?

[atkinsg]

Does anyone have a good idea on how to get outside air into the tank? Given that the tank is in the basement, in a room with no windows, and the skimmer is an AquaC Urchin so it has no air intake.

My problem is low pH due to excess CO2. I have looked at many air pumps, but none of them seem to have an air inlet that could be attached to an air line that I could run outside, or at least to the air intake for my furnace.

Any ideas would be greatly appreciated.

run a duct. like a dryer does.

how you inject that fresh air into the tank is up to you.

Ah hah, I recently had to do the same thing to fix my low pH. Bubbling air from outside raised the pH of a cup of tank water from 7.9 to 8.4!

Get a Whisper 60 or 100 ($25 tops) and an air tight plastic storage container big enough to hold it. See where this is going...? Now all that remains is a small GAC filter and 50' or 3/4 flexible tubing. Bingo, outside air bubbled right into your tank.

Get 2 air pumps and DIY yourself a nice CC airstone skimmer while you're at it.

I had this problem before with my aquarium.If you have a sump you could put an air pump in a well ventilated room with windows and run a long airline with an airstone in your sump.From what it sounds that would be your best bet.If you dont have a sump you could just put the aitstone in the back of your tank and put the air pump on a timer.Run the air pump during the night when the ph is at its lowest.

alpine,

I wish I had a well ventilated room. Unlike you lucky people in Florida, my whole house is sealed like a drum 6 months/year.

Thanks for the suggestion.

ChemE,

Where did you get your GAC filter?

 

[ChemE]

The trash can. Empty 2L Coke Bottle plus some GAC = great and dirt cheap air filter. This was also my water filter before I shelled out $200 for my Typhoon III.

It actually took quite a bit of hacking to make my avatar an animated gif and keep it under the 8K limit that RC allows. This image is originally like 50K and not as big.

get an air lifter. pull a 1/4" hose from out side, and pump it in the tank

Nevermind, I didn't catch that it was an Urchin with no intake.

240-Reefer,

Do you mean an Aqua Lifter?
