co2

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...

Hi everyone, I have a brand new Victor dual stage CO2 regulator for sale. I was planning on getting back into the hobby because our new baby, my wife and I think it is better to wait and as result will be selling the few equipment pieces that I have. The regulator is a victor 4000-9429...

Hi all, Brand new user here, and praying this gets some traction. I'm embarking on a sort of ridiculous project that it seems like this forum is uniquely poised to help with. I am a PhD student at Duke University studying the functional genomics of how calcifying marine invertebrates (think...

Hello so I have a 75G mixed reef but mainly SPS dominant I have a lot of frags not yet mini colonies only about 3 are but not very big anyways. I was running my pH 7.8-8.05 before anything then I purchased a co2 scrubber and recirculating it I’ve raised my pH to a low of 8.0-8.2 with a high of...

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...

Hi all, I'm looking for a bit of input on how I can hook my ozone generator up so everything is as safe as can be. The picture below is how my set up looks right now. I have the BRS CO2 scrubber connected directly to the X-120 skimmer. I haven't been able to find much info on connecting Ozone...

Bought this new a few years ago. Used it on a freshwater planted setup for about 8 months then took that tank down and this has been in the box since. The tubing is Co2 resistant. The diffuser is high quality and ceramic. I cannot recall the brand name at the moment. The tank is 24oz and...

Hey Guys, I am working on a project that can measure how much dissolved co2 is in my aquarium. I have overcome a few of the major obstacles, but I have hit a bit of a wall. Has anyone done this? I am using henry's law to figure it out, if that means anything to anyone here. My current problem...

Hey guys, According to my Seneye Reef, my pH is at 7.8 and has been dropping for a while until now, not dramatically but over a long period of time and seems to be settling at 7.8. I've been testing my alkalinity during this process and my alkalinity comes out at more often around 3 Meq/L...

Is there any use in a reef for spent soda lime or a way to rejuvenate it to use it again? I have medical grade that changes colors, probably what BRS uses but didn't get from them.

Since R2R has been such an amazing source of knowledge for me through out my years in the hobby I want to share this idea with you all.

Hello all! My freshwater Co2 tank has a little aqauaponics HOB filter..Planted In that I put Forget-me-not seeds. They all sprouted and are growing from ambient light, some sprouts even took to latch on my waterfall, haha..Under the T5 fixture. Well this morning I have noticed very pretty...

I’ve never made a build thread. Figured I’d give it a shot. I currently have a 105g DSA tank and have tangs and a trigger that are outgrowing it. I purchased a 140g tank that has been floating around a few local members and was never set back up. Tank is 60x30x18 and the fish should like it...

This regulator is in good condition. Im asking $80 shipped.
