Loved the glycerin tip - I knew people used something other than water, but didn't know what it was until now. Thanks!

Been following this man and the team over at Green Aqua for so many years when it comes to freshwater.

I think using glycerin is my last mistake to fix. I knew I'd heard someone mention something besides water in the bubble counter before, but couldn't find it. Glad it was mentioned here!

Gute, nützliche Tipps zum Thema CO2! 😉

While a drop checker is better than bbs, it’s not actually that accurate.

What about inline diffusers? Glycerin was a good tip, I’ll try that one.

Thanks so much. I just bought my first co2 regulator from co2art. I cannot get the diffuser to bubble. Now I believe I have water in the line. I'm going to open the regulator and let it flow and see if it starts to bubble.

Diffusers can take a bit to show bubbles. Sometimes bigger ones first then smaller ones. You can crank up the flow temporarily to push it through and get it going faster then back the flow down.

Was just cursing my bubble counter being out of water again, not 20 minutes before watching. Glycerin will be here tonight. Thanks for the tip.

Glad to hear this helped!

Is glycerin safe for the ultra fine defusers that warn against using mineral oils or any kind of 'bubble counter fluid'?

If glycerin or mineral spirits were to get to your diffuser, you would need to replace it. But that is unlikely to happen (at least in our experience)

If i don't like CO2 bubbles... Can i set my difuser under de filter? The bubbles goes inside the filter and back to the water... Can it work?

Do you still add plant fertiliser to your tanks alongside the co2? I'm just in the process of learning about it and want to add a co2 kit and was hoping to cut bk on all the chemical fertilisers in my tank

May depend a bit on your set up - but while the combo of CO2 and ferts will likely result in the best plant growth, if your goal is to cut back on ferts go ahead and just use CO2. We have multiple setups with only CO2, no ferts, and they are doing great. That said, when your planted substrate deteriorates (maybe after a year) ferts may be a needed supplement for your root feeders if you’re not otherwise using root tabs or changing the substrate.

I have a bubble counter with water but.... it has a special hole where u refill it with a syringe. So no need to unplug anything. Its made by aquapros. Really handy.

What type of glycerin do you use?

Just a vegetable glycerin works fine

Glycerin, eh? Off I go get me some then!!

Is vegetable glycerine the same thing? It’s all i can find. And can you add food coloring to it to make it different colors?

That should work the same, but let us know if you get a different result.

maybe oil instead of glicerine??

Baby oil has been known to work as well. The viscosity will be different between water, baby oil, and glycerin. Just make sure you are checking your CO2 checker and adjusting the flow for whatever you are using.
