with your problem with fry going up the filter i had this problem once and i had some sponge from the fish shop cut to fit on the end co that they wouldn't go up but the filter is ot completely blocked so the water is still filtered
Hmmmm proplem with fry going up filter.
You could use the toe end of some large tights or stockings.
The filter is not completely blocked and water can still filter through.
