Breeding Tank Filtration

[Tal]

Hi,

I'm thinking of installing 215L tank external canister filter of 150LPH with sponge pre-filter.

Currently using sponge filter with air pump.

What is the best practice in breeding tank filtration? does low LPH won't disturb fertilization of eggs?

Thanks!
Tal.

Sponge filter. Cheap and simple. All you need.

Aight :) thanks.

I think you have to stop any external or canister filtration when the eggs go to wigglers, otherwise they can get sucked up, or stuck to an intake sponge. At that stage they don't have much strength or control, and the main challenge is for them to attach to the parents, so that's why everyone uses sponge filters. No currents in the tank. I just had a batch go through this, and now that they're about the size of a nickel or better (U.S.), I've started up a canister filter to improve circulation. Just my own routine. -Don

Nice idea, having external canister on when no fry or eggs are inside the tank.

So a Maxi-jet 1200 connected to a sponge filter might be too much then? Just use airline?

Best practices in breeding tanks is to avoid water flow. Male spreads liquid to fertilize the eggs, that liquid might get swept away with the flow and by that reduce significantly the success of the spawning.
