How Many Bubbles Per Second Should I Be Aiming To Have Entering My Co2 Diffuser?

After being out of the hobby for 15+ years, I am soon to be setting up a small 130ltr Aquastyle tank. I am aiming to scape a live planted tank and I still have my co2 bottles, gauge, etc. but no diffuser, but have totally forgotten the important numbers, I wonder if someone could advise me on amounts of co2 I should be using. I intend to buy a JBL inline diffuser, a system I have never used before now and would appreciate any hints/tips on its set-up, specifically the bubble count.
Also, I have read good things about the "1-2-grow" range and would like to hear your opinions on them or would you suggest any other supplier of live plants?

Yet the tissue culture range are very good for getting a lot of baby plants which you can grow on. With co2 injection you should be able to do this fairly quickly. I would highly recommend though getting some floating plants or something very fast growing such as elodea in the first few month of your aquariums life if you go with all tissue culture plants as you need good plant mass from the get go to avoid algae. These can of course be removed layer down the line.

CO2 injection is not something I normally use as I'm a fan of a low energy approach. However, rather than focusing on the number of bubbles, what you really need to do is a pH profile through a day testing minimum every hour. This will allow you to identify if you drop the pH sufficiently before lights on, if the pH remains stable through the lighting period etc etc. Roughly I would suspect 2 bubbles per second but the pH profile is the way to be able to identify what you actually need for your setup.  Thinking on co2 has developed significantly in the last 15 years and basically I'd recommend doing a bit more research to fully understand the up to date methodologies to maximise your chances of success.

 Cheers Matt, good sensible advice which I will take onboard and act on. I imagine a few searches using our friend Mr Google, will find me the facts and figures I need to successfully get my tank up and running without making too many beginner's errors. Thanks again...

  Hi JPC, thanks for taking the time to reply. Your advice on the number of bubbles will be invaluable when the time comes for me to set everything up. I was extremely lucky to follow a number of links on YT just yesterday, which took me to George Farmer, the aquascaper, and one of his videos explained the use of the "co2 drop checker" (lime green is go, all other colours fail, lol), so armed with my, as yet unpurchased, drop checker(more of a colour checker surely, oh well!) and your help re bubbles, I hope to get off to a less shaky start than would otherwise have been possible. Many thanks, TCS...

  Thanks again JPC, looks like I'll just have to rely on the "green is good" glassware. Luckily I am determined not to rush and therefore make silly errors, as I have done in the distant past. I realise now that by taking your time and getting all the parameters spot on before moving to the next stage is absolutely the right way to go.
BTW, I'm fascinated about your BC experiments. Please let me know when you have something working.
Kind regards, TCS....
