hay jim do you have to use a sponge filter for betta fry i read on your website that you use java moss to get infusoria for the fry but do you have to use a sponge filter for betta fry or you dont have to because sponge filter create to much turbulance anf force co2 out of your tank not good for plant but no sponge filter no water turbulance on surface and water tension to high kill all your fry what is the best setup to raise betta fry and grow plant at the same time. - Ha

Ha,

We always use a small sponge filter, but it is only with an extremely slow stream of bubbles. So slow that the water surface on the other end of the 10 gallon tank is not disturbed. The plants would be fine without the filter and the loss of CO2 is easily made up with a small amount of light. The reason for both the plants and the filter started with the concept of improving water quality for the fry. The side effect of both has been the infusorian sources for the fry. The filter needs to have air moving through it to keep the bacteria (those for both converting nitrites and ammonia) alive.

CO2 and O2 can both reach 100% saturation in the same aquarium setup. The two are not mutually exclusive…so a tank can have a high percentage of oxygen for the fish and a high percentage of CO2 for the plants. Any excess is loss through the surface. It is not possible (in an aquarium setting) to have “too much” of either gas.

The challenge with most plants is their need for a carbon source. Normally that is light. Some plants can do very well with less light, hence our choice of Java Moss. Most of the moss-like plants do fairly well to good in less intensive light environments. Anubias in generally are the same way. In high CO2 environments, more light is generally needed, so your plant choice can change, but then you are probably going to want to increase the amount of light. We have always felt that Bettas do better in moderate light situations and and not particularly “happy” in the bright lights of a intensive light setup…and that is why we decided to use J-moss…low light, lots of places for fish and fry to hide…covered with infusoria…it seemed to be a good choice (and still does).

Hope this helps a bit.

Take care,
