you can always find our sponsor for help.. thus the price offered may be better.. reef octo pump is not that hot though.. and u may not wan to use rio as ur return.. as i find that it wont last u that long.. and ur wave make and stuff, u can buy 2nd from the forumn.. as it will save u alot more.. and for the tank u going to have, the seio 820 is not enough.. the flow is too little.
