Okay , planted tank gurus need some sense shoved in my brain so i can sleep better....
I met few hobbyists here and we were talking and the discussion got into planted tanks, me being a total failure in this area could not debate much so i was more of a listener with embarassing head nods every now and then like i knew everthing...
My question is how do i connect all the below to make more sense to me.....or how do i determine how much of "each question" below do i need to have a good planted tank....
1 = they say if you have 2-3 times WPG lighting then there is no need for Co2 ????
2 = BUT Co2 makes plants grow faster
3 = BUT plant growth is based on substrate also
4 = substrate is fine BUT you need ferts dosing...
5 = What on earth is micro and macro nutrients ( i hated going to chemistry classes by the way )
6 = BUT there is low tech and high tech planted tanks
How do i find the perfect balance.....
I did not want to post back in the fish forum here fearing the embarassment of asking such silly questions but being on IAH for over 5 years would give me some credit i guess

1) CO2 for plants, is like oxygen for us guys.....without which plants will die. Its is necessary.
WPG - watt per gallon is the amount of light needed to grow plants. its an APPROXIMATE ratio, of the volume of your tank and how much watts of light you would need. WPG works most of the time.
2) More CO2 will increase plant growth. - true
3)Plants need nutrients, CO@ and light to grow. All in balance = Planted tank, not in balance = algae tank.
4)Ferts = source of Potassium, Nitrogen and Phosphorus. Carbon is got from CO2. These are required in large quantities, hence they are called macro ferts
5)Micro nutrients are required in small quantities eg: iron, copper, boron, etc (this is not a complete list, just what i remember at the moment)
6)High tech and Low tech planted tanks are a misleading title. Guys who go for expensive substrate, high wattage lighting , branded ferts, with pressurised CO2 call their tanks High tech. Guys who use mud, DIY CO2 and less light in their tanks term them as low tech.
