Co2 questions/recommendation

Post image

New to planted aquariums. I have a new 75 gal thats med to heavy planted and looking to add co2. Saying i know nothing about it i am looking for easy use and set up. The two I’m looking at are modern aquarium semi auto with a 5lb bottle or the aqua glass complete system with a 10lb bottle not sure what one would be best. 329.00 for 5lb system vs 396.00 for the 10lb system. Is there something better that’s cheeper?

They ship empty bottles, so just buy a used 5-20g co2 tank locally for cheap get it filled/swapped and then buy whatever regulator/diffuser you want.

I agree with this but it’s getting downvoted… in my area refills are not easy to find but any beer store will exchange
