Well if you have a bare bottom, I'd say you could add more. If you have a sand bed, then I think I'd not buy any more. I'm not sure what 75lbs of liverock looks like but I'm guessing your scape isn't "minimalist" and there might not be much more swimming space. Too many people only hear "50 gallon tank", when there are many factors to consider. I wont even talk about bioload...I'm assuming if you have that many fish already you know what the deal is lol.
May i ask why it would be ok to add more if he had a bb?
