Adding liquid CO2
#1
I’ve read online that the best time to add liquid CO2 is just before lights on. This doesn’t work for me as I’m at work during the day so when should I add?

My lighting is:
1pm - 30mins very low blue moonlight
1.30pm - 30mins sunrise low blue and white
2pm - 7 hours full daytime white/red/green
9pm - 30 mins sunset low white/green/red
9.30pm - 30 mins very low blue moonlight
10pm - off

All LED.

When I finally get round to setting up the tiny tank I’ll have a similar photo period just without the sunrise/set as the light won’t be as clever. So I’ll need to know when best to dose that too?

Total novice when it comes to plants etc Big Grin

When to dose for liquid "co2" isnt that critical to be honest as it's basically just an algaecide. Based on the photo period you want, I would just dose before you leave in the morning.

I would however go for a shorter light period, at least initially. Maybe like 6 hours. If your not home till 6pm then have the lights come on then and then dose the liquid co2 then.

I dose mine when i leave in the morning ( 7:20am ) and my lights don't come on till 10am. Keep it consistent and the time doesn't really matter.

Been reading up on Liquid CO2 and some of them (saw one on Amazon) uses 2% Glutaraldehyde in the solution. This chemical was banned in the NHS donkeys years ago and is only allowed in certain things such as cosmetics up to 0.1%.

Done a bit of googling about glutaraldehyde and it’s a bit of a minefield isn’t it.

What I can make out is the proper branded versions (of which mine is) used at the correct dosage with common sense precautions you should take when dealing with any chemical you shouldn’t have any adverse effects.

Obviously using anything not proprietary or using too higher dose or sniffing it etc will have the potential to cause issues.

With the dosing if time of day isn’t a major factor just consistency then I’ll do it first thing I think as that’s an easier routine to keep to.
