Switching to low light plants

[squall99e]

Recently switch to low light plants like nana, Aponogeton boivinianus, Blyxa japonica, Cryptocoryne balance, Cryptocoryne wendtii, Echinodorus horemanii, Echinodorus Rose, moss and Hygrophila lacustris(the only high light plant)

For such tank, do I need to maintain 20-30ppm CO2?
Nutrients like PO4, NO3, K and trace be maintain like in high light tank but does less often?

I have 4 X 36 FL light 6500k currently on 3 to make it 1.98watt/G.

What points do I need to take note when maintain low light tank?

You would need to consider whether your current bioload is high or not...the rest is basically the same unless you want to go the non-CO2 way which is another whole new ball game.

Peter,
My bioload is not high before I try this low light tank as i need to add additional PO4 and NO3 every 4-5days. Just have to monitor for the next few days. To me CO2 is a must.[]

Thanks for reply
