Hi there all,

Great post.

I had lost 25 platty fry due to powerful filter, did alittle mod & stopped losing fry but they were still having dificulty with flow near filter. Then I saw this topic.

Made mine with a Nutrafin Cycle 250ml bottle with top cut off, Fluval 3 blue filter element (old style, long round with central hole), 20mm white plastic water pipe & two heater suction clips (lugs cut off & cable tied to bottle). No need for gravel as suckers keep it in place.

Haven't had it set up long enough to see it it keeps the stats right but water flow seems good.

Will be making another for my second tank as that could have fry in it shortly.

Thanks for the ideas.

Norman

Hi all, just want to say thanks, this just may well save my fry which came as a bit of a surprise.

I didnt have time to be able to go my nearest LFS to get equipment, so i used a small food container from asda that i had laying around, with a couple of snippets of mature filter foam and gravel from my big tank (240 litres).

I used a piece of sleeving from an old rounded ide cable that i had kept after snapping a connector off of it.

It works beuatifully, i can see its drawing water in because theres small bits of food trapped on top.

The top of my tube is about 3mm below the water surface and is turned down really low via a inline control valve.

The fry aren't being battered about and hopefully, they'll grow up to be big and strong guppies.

Thanks again, absolutely brilliant idea and thanks for sharing.

Hi. Im quite new to this site. I had a read of this topic and noticed a lot of people asking questions about how the water gets in...
Hopefully this quick pic will help others.
The central pipe is the outlet for the air and filtered water.
When the air is pumped into the central pipe, it rises. When it rises, it pulls some water with it. This water is then replaced with water that has come from the tank, down thru the filter and gravel then up the central pipe again.
Note that the top of the central pipe is below the water line. This makes the water flow out into the tank easier.
Well, here goes.

hi, would it also work like this

so the gravel keeps the air tube in place also and the air will be coming out at the same spot at the bottom of the wider tube

Wow! I'm glad I was looking around & found this. I'll have some fry in the near future & wasn't seeing any of of the sponge filters online at Petsmart or Petco. I used them years ago in my cichlid fry tanks and was wondering if they even offered them anymore. Now it doesn't matter. I'll probably cut up one of my Eheim coarse filter pads for that top sponge. Thanks! :good:

is this safe to use in a fry tank or will they get sucked in? :unsure:

They will not get sucked in, as there is sponge on the top to prevent this and other materials getting sucked in (thats the idea of the filter lol). I must say this is a GREAT idea for a sponge filter, I really love this idea and I get you a 10/10 for creativity and ease of creation.

yes you can use any type of pot you want as long as you are sure it is safe to put in an aquarium. any food safe plastic is fine :good:
