I used a koralia magnum 7 in a 40 breeder... Lol... I have also used many others up to my vortechs... I personally don't care for them and feel they aren't suffice in SOME cases, and are jus mediocre quality products in other cases, at best... Not telling u to go out and buy ecotech products, but there are better choices than koralias, ESPECIALLY when using them in a wave maker way...
Jus IMO... Nothing more...
