Guys . those protein skimmer u all talk about is external or internal ? cause if i use internal. then the space in my tank is even smaller. But, for external. I dunno how the thing is going to work. For the JEBO HOF. i think that is more suitable. But i dunno the effieciency of it. Sorry guys. I know i sounded real dumb . haha . but i already try reading alot alot of it. And right infront of me now is 5 books about marine fishes ! . And Violence, i know abt the risk of nitrites in my tank. But will growing the algae helps ? will anyone recommend doing that?
