Retirement and forum shutdown (17 Jan 2022)
Hi,
John Howell who has managed the forum for years is getting on and wishes to retire from the role of managing it.
Over the years, he has managed the forum through good days and bad days and he has always been fair.
He has managed to bring his passion for fish keeping to the forum and keep it going for so long.
I wish to thank John for his hard work in keeping the forum going.
With John wishing to "retire" from the role of managing the forum and the forum receiving very little traffic, I think we must agree that forum has come to a natural conclusion and it's time to put it to rest.
I am proposing that the forum be made read-only from March 2022 onwards and that no new users or content be created. The website is still registered for several more years, so the content will still be accessible but no new topics or replies will be allowed.
If there is interest from the ITFS or other fish keeping clubs, we may redirect traffic to them or to a Facebook group but will not actively manage it.
I'd like to thank everyone over the years who helped with forum, posted a reply, started a new topic, ask a question and helped a newbie in fish keeping. And thank you to the sponsors who helped us along the away. Hopefully it made the hobby stronger.
I'd especially like to thank John Howell and Valerie Rousseau for all of their contributions, without them the forum would have never been has successful.
Thank you
Darragh Sherwin

You can go as high as you want with the CO2 in a plants only set-up, when adding fish you need to be more careful as you can kill them. I have a JBL permanent CO2 test, but it's not very reliable, so I just stopped short of fish gasping for air. It is trickier to get the balance right, but your fish will be the best test of the amount of CO2 in the tank.

If you are using T5 High outputs and the Tank depth is around 18 Inches, you will have no problem growing the easier Plants.

T5 Lighting works well as long as you have a good mixture of light CO2 AND air-
The CO2 is really setup easy.
Ask away what help you need.
Most of them are co2 tank,air bubbler valve,co2 diffuser and some connect to the external filter. with the diffuser.You could also buy a solenoid valve that will open and close on a timer for whenyou have bubbles per minute setup

The purpose in adding CO2 is to get more carbon dioxide into the water, presumably to increase plant growth or sometimes to lower the pH (it does this notwithstanding). Any device that causes surface disturbance or excessive water movement increases the exchange of gasses at the surface, by expelling CO2 faster and bringing oxygen in faster. So in this regard, the two systems are working at cross purposes.
Assuming your use of CO2 is for plant growth, this can only help during the daylight since plants do not photosynthesize during darkness. Therefore, CO2 diffusion is usually turned off during darkness, otherwise it is just wasted and may cause a serious depletion of oxygen. At the same time, those with heavily planted tanks sometimes suggest running an airstone at night to ensure sufficient oxygen. This is only necessary in tanks with CO2 diffusion during the day.
