I am considering consolidating my 45g attempt at a brackish planted tank into a 20g freshwater planted tank with lots of snails (for my puffers) and a few fish.
I would be using a 50/50 60 watt PC
, so 3 watts/gallon.
I don't know much about C02 or particularly want to spend the money on a system, so just wondering if algae would take over at this lighting level or if I need C02 injection.
If I do need it, is there a supplement I could use rather than having to inject it?
If there's no way of getting around c02 injection, can anyone recommend me an idiot-proof kit that would be suitable for a tank this size?
Any input is appreciated,
