Well I am new to this hobby and I learning so please bear with me. I have a 55 gal set Saturday. I have 60 pounds of Eco complete substrate and marineland penguin 350 hob filter. My question is will my filter be enough for discus? I was thinking of running two but one of my lps chains said it will hurt more then help. I did take it with grain of salt because he told me tiger barbs go good with goldfish. I wont over board on the questions just yet!
