Hello All,
First time poster here. First of all, thank you for all of the knowledge shared here. I've spent countless hours reading this forum since August when I took the plunge into a marine aquarium.
My wife and I were discussing the daily PH swing earlier this week and she remembered that soda lime is used in Anesthesiology to remove CO2 just like a CO2 scrubber we use.
Per Wiki, during the administration of general anaesthesia in hospitals and veterinary clinics, the gases expired by a patient, which contain carbon dioxide, are passed through an anaesthetic machine breathing circuit filled with soda lime granules. Medical-grade soda lime includes an indicating dye that changes color when the soda lime reaches its carbon dioxide absorbing capacity.
Thursday, the hospital was changing out the soda lime on an anesthesia machine and she brought it home. The product is called Carbolime by Allied Healthcare. It is in a very nice container with one input and one output hole each on top. The input side has a sponge filter at the top and the output side has a pipe going down to the bottom of the container, thus pulling air from the top to the bottom. A barb fitting from one of my pumps fit into the canister perfectly, and another barb fitting fit perfectly over my skimmer air intake. It was really too easy to install.
I installed it at 19:30 last night when my ph peaks for the day. ph was 8.0 - the high for the week was 8.02
At 19:40 ph had risen to 8.03 - while the lights were declining...
This morning the ph had dropped to 7.92. Previous 3 day average low was 7.78
I'm anxious to see what the ph high is today, and how many days are left in the container... Per manufacturer recommendation it should be changed out when 50% purple.
I could not find a single reference to Carbolime and aquarium on Google so I don't think anyone has considered using this product for our purpose.
Even if the soda lime is too spent to bother with, the container is a great little container. It's made like any other reactor we use. If I can get it open I could see using it for biomedia, carbon, or maybe even GFO!!
I'll update new peak ph and how long it lasts. This canister was just over half purple when I installed it. I included pics of my install and my APEX ph graph.
I apologize for the long post, I type far more than I speak in person!!
