I use thefishcave frysavers which have their own airdriven pump but sometimes the intake can get blocked and the saver gets full of crud build up. An extra airstone helps a little but not a lot.

This Aquarworld IP250L 4.5watt, is a filter small enough to fit in a frysaver and is fantastic for the current loving pleco fry. Its basically just a sponge, a rotor and a spraybar.
At 250lph its got plenty of grunt, just direct the spraybar to suit in terms of intensity of current and the little short rotor hardly ever gets blocked.
The sponge can be removed and rinsed during water change and its good to go again.

I have tried other sorts but they are more expensive or too tall for the saver or block up too easy with very little current.

Using this filter I have had up to 100 little fry in a frysaver and raised the lot no troubles with a very good growth rate.

Just thought I would share. I got myself a couple more for other frysavers today from here: http://www.theaquariumcompany.com.au/pages/products/product/250-aquarworld-internal-filter

Here is a photo of thefishcave fry saver from their website. As you can see, the gauze covered intake is inside the fry saver and is designed to remove debris and new water is pulled in through the large sponge at the side.


This works well until a bit of cucumber or wood shavings from panaque fry clogs the gauze bit on the intake and you don't notice its happened.

As well, there is no surface movement of the water so any oxygen in the water is dependant on what gets pulled in from the main tank.
I usually add an air stone to the fry saver just to make sure there is oodles of air in there especially for a large spawn of fry.

Usually I have several little bits of wood in the saver for cover for the fry and if they are bristlenoses or panaques, for them to gnaw on.
All those little tiny useless bits of drift wood you would normally discard do come in handy in a fry saver.

The trouble is, if the fry are only little with little swishy tails, they aren't going to be able to push enough of the debris over to the pump intake and it just sits around in layers amongst the wood and rots. Bad for fry to eat.

So I do like to add an itty little power filter. This is where the little AquarWorld filter with the spray bar comes in handy. It clears that debris either into the pump intake if its not blocked and/or to the sponge in the filter itself.

Other power filters have an added carbon filter section which makes the filter too tall to fit into a fry saver. Although half the time my aquarworld filter isn't even suctioned onto the side of the saver, the spray bar does at least hold it in some semblance of an upright position.






Little short rotor with a nice big fan, hardly ever needs cleaning.


The rotor cover has an adjustment to control the level of power. My first filter is so old I have lost the adjustment bit and the two suction cups which tend to fall out when you disassemble it but it still works just as well.


Quite important with the sponge, make sure the hole part matches up with the rotor on the correct side. The hole creates a current vortex with the rotor and really draws the debris into the sponge well.
If you are cutting your own replacement sponge, make sure you also cut a hole in that spot.
