hi, i am trying to get in use with this planted tank hobby

but not sure if the planted tank must have co2 tank?

coz i see got some people can grow the plant without co2 tank, so how he/she do it? only use special soil and some lighting?

thanks for both well reply


hmm..looks like i need to start this new venture hobby with a small tank...then put some soil and sand...and choose the plant that have minimum co2 requirement

i must say, ur guys have really amusing planted tanks, feel like really in the nature

just went to local fish shop somewhere in ampang, near to mrr2 highway (got 1.5 foot banjar red and 9 foot aquarium at the shop main entrance)


i noticed got 1 co2 device, just a small tank, like a ridsect or something, price tag RM58, the shopper say, just press 1 for a day and it will supply enough co2 for planted tank


and another option is automatic 1, RM148, refill available

is it ok to use that instead of big co2 tank?
