our amazon swords are starting to look a little sickly, with the bigger leaves going translucent. Is this due to not having enough lighting, or can anyone suggest anything else that might be wrong? currently, I'm using the standard Juwel Rio 180 built in lights (2*30W tubes with reflectors). The tank has a gravel/flourite mix substrate and JBL Co2 system.
thanks
Nik
