Kittiwakes low light tank
Tank 180L(47.5g) Lighting 2.4wpg, no CO2 injection, no significant plant feeding except regular water changes, fish waste and the occasional plant food dosing (~once a month). Whilst things don’t grow like crazy there is reasonable growth. If I spent a bit of effort on the plants I could probably get better growth but I am happy with how it is. Only problem is Amazon sword grows out of tank then frazzles its leaves on the luminaire.
