im struggleing here... please help me understand something. in simple terms, the amount of water passed through the sump. if it is more then the intake of the skimmer, then the skimmer will not function to its potential. correct? example: 600 gph return on return pump with a 300gph skimmer, would mean only half of what pass through the sump would get skimmed. ok, so then how do you get the entire amount of water passing through the sump to be skimmed? my only solution would be a external skimmer, that is fed with a downdraft. i have a open sump with no baffles, is it better to have baffles, or a skimmer with a larger intake rating then my return gph? one more question? with the rite kind of thought process, and planning (careful planning) can any skimmer be turned into a recirculating configuration, where an external feed can be installed? thanks.
additional info. my tank is a 150 tall with a 25 gallon sump. i keep sps and i love fish! lol ive been battling nitrates as well as phosphates. lets say money is not a concern and see what info i get. what ive been looking at the most is the skimz 162 external and anything with a bb 3000 on it. thanks.
