In my two Dennerle 10g’s I have always used GLA atomic diffusers as well as Dennerle Eckfilters.
These are both shrimp tanks containing BKK, Blue Bolts, & various neocaridinas, which is irrelevant...
I find that cleaning the Dennerle Eckfilters can be quite a pain in the butt, also it’s lack of biofiltration after cleanings.
I use sponge filters in my other shrimp tanks but because these two tanks run CO2 I have chosen not to have an air pump running all day (only when the lights are off).
I have made a few changes to a sponge filter thinking that maybe I can figure out a way around this problem.
I’ve attached a small submersible pump to the top of the sponge filter to avoid using the air pump. Where the air tubing would normally attach I was thinking about hooking my CO2 line.
I am very hopeful that this might help CO2 dissolve better into the water column after running through the submersible pump.
Does anyone know if I will be able to get away with this setup without having to use any type of diffuser INSIDE of the sponge filters tubing, or if this will be safe to run?
I have considered that I possibly might need to make some type of spray bar and have the CO2 line come in at the base of the bar where it meets the pump so that I do not have air bubbles running through the pump if it turns out that it could be damaging it.
