How quickly is it growing back? It might grow back too quickly, but you could try.

Using a siphon to suck it out should work pretty well. If you use a small diameter hose (like airline or a sniff bigger) you will get out more of the dinos and less of the water so you should be able to suck it all out in one go. Turn all the pumps off while you're siphoning so you get minimal dinos into the water column.

If you could catch the fish you could put them in a Rubbermaid with airstone, heater, and some hiding places while you do the cleaning then run HEAVY carbon for a few hours, then put the fish back and do the black out.
