Most of us are aware that stable CO2 levels are necessary to help prevent algae issues.
My question is can we drop CO2 levels without causing an algae bloom?
Here's my situation.
I have been injecting silly amounts of CO2, as I have no fauna in the aquarium. We're talking 50+ppm CO2, probably.
Now I want to stock some fish, obviously I need to reduce this to 30ppm CO2 maximum to be on the safe side. Ideally I'd like around 20ppm, as I've noticed most fish tend to be more active and eat better with CO2 levels below 30ppm. This is anecdotal evidence, but enough for me to believe it.
So am I likely to experience algae issues by dropping the CO2 by such a considerable amount?
Tank specs -
24w HO T5 over 60 litres.
Planting is around 20% footprint coverage of hairgrass.
Ferts - 5ml TPN+ and 5ml Liquid Carbon per day.
Filter - 1200lph external.
Water changes 2x 50% per week.
As I'm writing this I think I should be ok, with the combination of moderate-low lighting, decent filtration, liquid carbon, and water change schedule.
Thoughts welcome, especially from the likes of Clive, our resident Neo...
