I've been running a jebo R390 ( 200L ) with CO2 for about 4 weeks now, my first tropical tank.My other tank is a 360L reef system, so i'm not new to fish keeping however i am new to tropical.
I think its the same with everything if you buy all in one units you probably wont get the best of every thing.
So if you don't over stock with fish or want plants with high lighting needs there not to bad for the price, also i was drawn to them for the seamless curved corners on the front of the tank.
Looking at the lighting hood and overhead filter they can quite easily be upgraded to house more powerful lights and add an external filter if needed.
but the way i see it is to try and create an ecosystem that requires minimal man made filtration.
Nature dose it all be it on a much grander scale, i don't see why we cant have our own little bit at home.
So i guess that says that jebo get my thumbs up, do your home work and buy a system that will suit the type of habitat you are trying to create.
Not a well known brand anyhoo, I would just recommend juwel
