Actually there is a way of removing the suspended silt. Put the water in a holding container and then let the silt settle out. Then siphon off the top layer into your tanks.
The problem you guys have is that your populations of critters can't keep up with the algae that is being produced (have you introduced them yet or you just have green water in the tanks?). You could introduce FW clams or mussels, they do a great job but you are also introducing potential contaiminations into your water depending on what you are doing with your critters after they grow (ie. feeding them to larval fish etc).
If you don't have critters in your tanks, depending on how big the tanks are, you can empty them and clean them out, then refill them with unfiltered water and let that sit and then use a siphon hose and gravel vac the bottom.
Just how big are the tanks anyways?
