co2

I’ve been dealing with consistently high CO₂ levels in my condo and I’m trying to figure out the best way to manage it—both for myself and for my reef tanks. I’m on the first floor and I do have a lanai, but I rarely keep the sliding door open. Living in Florida, leaving a window or door open...

I have a new 2.5lb CO2 cylinder that I’m not going to use. I bought it because I was planning to run a small calcium reactor but changed my mind. It’s empty and has absolutely no damage—not even a scratch. $25 and it’s yours. I’m in the Madison, AL area. Let me know if you have any questions!

As tittle says, looking for Carbon Doser regulator. PM the picture and price. No scammer please. If you’re local to NYC, I’ll be interested in CO2 tank if you got any

Co2 media is just Kalkwasser, IceCap media sucks and it’s hard to find lime crystals vs powder. How long would activated carbon last in a co2 scrubber?

Have a Reef Octopus Classic 110 INT Protein Skimmer with CO2 recirculating lid. Trade coral or sell, unit about a year old, I upgraded skimmers as I needed more of a PH bump. I’m here towards Denton/Corinth area

My levels were over 2000ppm, which is enough to cause drowsiness in humans. I found out after getting a CO2 meter (Aranet4), although this is not an endorsement for that brand in particular. However, I do that knowing the levels of CO2 in your house is worthwhile. Once I took actions to reduce...

A newish tank (2 months old) with low nutrients and no algae, has low pH 7.8-8.0. It is a 30G tank running a canister filter (crazy, I know) with SeaChem Matrix and ROX activated carbon. I dose live phyto twice per day. There is no sump There is no skimmer There is no space under the tank for...

This thread is to study the effects of operating a super saturated small media bed CaRx (S3MBR) using the super saturation of CO2. The premise is that a S3MBR should be able to to achieve performance equal to, or exceed the performance of traditional larger CaRx reactors that rely on media...

Trying to figure out the best way to give co2 to multiple tanks Can I get away with just using fans? If I have relatively high c02 in the air how much is actually available under water? Is there an advantage to using citric acid/baking soda or yeast/sugar or refilling a standard co2 canister...

Hi everyone! I need some advice and this is the best place in the world for high quality reef advice, so please bear with me and thanks in advance for your help! Basically I was skimmerless for a couple of weeks after removing my previous skimmer to prepare the sump for a skimmer upgrade and...

Hi all, I will give some more details to the title. I recently started my adventure for the first time with saltwater aquaristic, so I have no N years of experience for supporting my claims. I come from freshwater, and before that terraristic (bearded dragons, newts, frogs etc) and a common...
