Try a low-tech crypt tank. Some recommendation.
Lights: 1.5 to 2 wpg
CO2: none
Substrate: good base fert + peat (0.5~1cm) + gravel
Fertilisation: no need to fertilise so frequently... only when needed
Water change: about 1 every 1 month or 2, after tank stabilised
Try to plant as densely as possible from the begining. Start with some hardy Crypt species like C. wendtii, C. albida or C. undulata. Sensitive crypts can potentially melt down and fouls the tank, especially when it has not stabilised.
