I have my fry in two different 200 gallon tanks with water filled only half way. I took about half of my water hycinths out after the eggs hatched but noticed that the floor of the tanks were really dirty with all the roots of the hyacinths floating around and dead leaves. How do you guys clean that up with hurting the fry or destroying them. I have four 8" airstones in there only and no filter. Do you guys have a filter, if you do how do you clean the bigger debris without destroying the fry.
Also when you guys do a water change how much water do you change and how often are the water changes. I plan on doing only once a week.
Thanks
