I´m a cichlid and aquatic plant lover myself, and these two often come into conflict
Some vegetarian cichlids eat them, and many carnivorous cichlids tend to ust rip them up.
For me aquatic plants serve a dual purpose, beside their aesthetic value, their ability to use nitrate is a main draw.
So I use planted sumps to fill both aesthetic and nitrate detoxification
My 180 gal cichlid tank is filter with a 125 gal heavily plant sump


When living in the states I did the same thing.
For every 2 or 3 cichlid tanks, I´d employ a large heavly planted sump


In most cases because I would only keep a pair of cichlids per 6 ft tank, a planted sump like the one below, could easily handle the nitrates porduced in 3 or 4 cichlid tanks, reducing concentration to below 5 ppm.
