How to stop fry from being sucked into the filter??

I have a little 10g "nursery tank" and my 3 pg platties have given birth (so far I only see 2 little newborns, but there may be more). Problem I have is that I have the filter that came with the tank - an Aqua-Tech Power Filter 5/15 that has a pretty powerful air flow (stronger than I would like in this tank) and the suction will suck up anything that wanders by the intake. I tried putting some small netting material over it, but it restricted too much of the detrius and got the tank kinda polluted. I just don't want the fry being sucked up into the filter... Any ideas for preventing the fry intake but not the "crud" intake?

One thing you could do is put a nursery net into the tank - the fine mesh kind. That will stop the fry from being sucked into the filter, and will also make feeding easier.

Kateyoup, the only negative about that is that I would have to put the mommies in the net waiting for birth, and that kinda defeats the purpose of having a nice peaceful 10g for the purpose of waiting it out. In fact they would have gone nuts already in a net - they've been looking like they will explode any second now (and in the 10g) for about 2 weeks. They would have aborted, commited suicide, or something terrible in a net for 2 weeks plus (since they haven't all given birth yet, and the one that is, isn't through based on the size of her belly). I want them to be happy and swim around like normal rather than be in a tiny little cage - which I could have done in the "mother tank" (my 55g livebearer tank that they came out of to have a peaceful maternity area). I'm stumped. I really hate the super strong flow that the out put of the filter shoots out as well, it's very powerful and the smaller fish have trouble swimming thru it.

Help... anyone with more ideas??

take a CLEAN sponge with nothing in it and rap it around the intake then take a rubber band and put it on it. :D this should hold.

i've heard of people putting panthose onthe end of the filter. it is small enough for babies to not get through and porous enough for the water to still get filtered. i have't tried it personally but it sounded cheap and logical. though you would prob want to change it fairly often.

Thanks guys for the info, though honestly I don't see any difference in these ideas and the small plastic mesh (like oranges come in - but smaller holes). It lets more thru than panty hose or a sponge would, and still clobbers up the tank. Things like little tiny pieces of plant matter that the fish break off, small/tiny pieces of zucchini and cucumber and peas that they bite off, and little leaf pieces from the plants - these are the things that are polluting the tank, not the water per se.

A stocking is very fine and can cause clogging easier. Plus it can easily can get torn and does not last long. On my Marineland 280 and 400 filters, I use netting, but from a fish net. I cut up an old fish net and just wrapped it around the intake and use a rubberband to secure it. I later made it permanent and used aquarium silicone to secure it to make them look like this...

Since it's made from the net, it's very durable and can be cleaned and scrubbed without worries about ripping. Since silicone isn't a permanent bond, I can easily remove it by picking and pealing the silicone off.

On my Eheim and Rena filter intakes, I use a sponge.

eddie, that's about what my small mesh cover looked like on my little aqua-tech filter - but it kept clogging up with veggi matter (zucchini, carrots, cucumbers, and peas) along with little pieces of plant roots and leaves (things that were small enough to go into the filter had I not had the mesh on it). It just got nasty looking and I had all kinds of "stuff" floating around in the tank. When I took the mesh off again, it only took about 30 minutes or so to clear up the tank again. I am almost hesitant to put it back on again... How do you keep it from getting clogged up? I know this seems like such a dumb question, but when I would take it off to clean it, everything just turned loose in the tank mucking it up again.

I do get some plants getting caught on there, but I just leave it, becuase it doesn't really slow down the flow on my filters. As far as food being on there, eventually, my fish/shrimps pick at it or it eventually breaks down that I don't have to worry about it. If I feel like it, I just suck up the plants that get stuck during a gravel vac.

Since you have an AC filter and the intake is round, tube like, I suggest using a sponge. Many people using the AC sponge media and cut a hole in the middle to insert the filter intake. The best way is to soak the sponge with water and freeze it, then drill the hole. This leaves a cleaner looking hole.

Would this then be what I should be getting?

If so maybe the adapters it mentions would make it the right one for a 10g.
