sponge filter
 

yeah im going to setup a molly breeding tank and im afraid of the wee little fry being sucked up by my filter. does anyone have a good link on how i can convert my filter into a sponge filter?? and also do undergravel filters suck up fry??

Re: sponge filter
 

What filter do you use?
I don't think it would do harm on the livebearer fry but it will be a different story for fry of egg-layers especially when they are kept in pits dug by their parents. As the livebearer fry are pretty much well-developed, the chances of them being sucked by UG filter may not be high.

ok. i have 2 filters in there right now for my 2 fat and small goldfish that ill soon be moving to a 30 gal. but there just little filters that came in a kit. i think ones an aqua tech 5-15 and the others a some kind of brand 10-20.

place an aqua clear 30 sponge over ur filter intakes. dig out a lil hole in the sponge for the pipe to fit in, being careful not to tear through to the outside.

something like this? http://www.fishforum.com/viewtopic.php?t=1501 that one has carbone in it but i made one with just a sponge

Here's asimple idea for you, but it may get removed.
