So tell me if people think this will work. The pump I have that I trust and doesn't appear to be too loud is the wet/dry aq-6000. It seems to have plenty of power. (Up to 900 gph).
Now the problem with the sump... I sort of can't get anything under that thank that is larger than 12x20x30inches. which means I can't do a 55. I was thinking of the following.
Basically since there are 4 drilled holes, and I don't want dead water I will drain out of two holes. Each will run into its own in essence strong garbage can with sponges. Then those will have two holes (low and high)... piped into another garbage basket full of bio balls (I have some any might as well use them...) From there I will pipe midway and high to a 4th can that will only hold the pump which will return through either 1 or 2 holes. (I don't know what would be better split the pump exit on the top or the bottom? My physics mind says that each turn will cause a large loss in water flow so the later the better, hence me thinking only 1 hole.)
I will draw some quick sketches tomorrow seeing as it is ~2:30 am I think I need some sleep.
