I recently planted some C balansae in my 400 litre tank, which is fairly mature, in the hope that it would act as a nice contrasting background plant to my broader leaved swords. My question is, given my parameters detailed below, how long should it take for this plant to reach maturity? The plants have been in situ now for 2 weeks and i have seen no sign either of melt or new growth. The tank is 70 cm high so i was hoping the plants would reach this height over a period of time. Parameters: temp - 28C Nirtrate - 10ppm dosing - 40% wc weekly - Seachem trace and flourish dosed. Potassium dosed weekly. No N or P as both dosed with fish bioload. kh - 4 degrees Substrate - all EC I use RO water remineralised. I know these plants tend to be slow growers?
