If you want to raise your own in a separate fry ( I use one of these vegetable bins which holds about 200 gals of water) tank, an underwater filtration system would work temporarily. You could "DIY" an underwater gravel filter.
By a small cheapie circulating pump. Put it at the bottom and in the middle of the tank. Get some 3" or 4" PVC pipes and 4 elbows and use it as a framing around the inside of the tank (Must be high enough to clear the height of the pump, which will create a gap for water circulation underneat). Get what they call "Egg Crates" looks like one of those flouresent light fixtures made out of plastic with grids, and put that on top, then line the top with some stainless window screening. Put Aquarium Gravel on top (not sand). The return line could be splashed back into a corner of the tank through some large rocks to create some aeration.
You could put a splitter on the return line and the end of one of them would have a valve going outside the tank for when you want to dump and replace water.
I want to stress that this is just temporarily since the gunk is getting trapped inside the sand and at the bottom of the tank. Minor disease problems can be controlled with a little Methelyne Blue. But all we're trying to do here is keep the water clear until the fish are big enough that we can modify the setup for proper filtration. It doesn't take long for fry's to get big enough so that they don't get sucked into the pump. Under proper conditions, it takes about 3 weeks to a month.
Hope this makes sense.
Best Regards
