Hey all,
in my 5.5 I'm having issues with very timid dwarf emerald Rasboras... that is a topic of its own and its likely I will resolve the issue by relocating the hyperactive danios to another tank of ours....
My questions is about the filter... I have a "10 gallon" sponge filter and for a base it has a canister of substrate I assume is for biological purposes (I regret not replacing the stones with ceramic bio nodes for the cycle) and on full air pressure with a "10 gallon" whisper pump, there is a knocking sound caused by the build up and then popping of air pockets in the canister of substrate under the sponge. I miraculously was able to remove the bubbler and replace it with an airstone with some ingenuity, and that didn't help. If I turn the air down substantially, the knocking goes away, but my though it, as an ONLY MEANS of filtration, the more bubbles, the more "flow"
BUT, does the knocking make the timid fish even more stressed?
on a side note, this has inspired me to build, from PCV, bio nodes, sponge, and filament, my own air powered filter, I just need to do so in an unpopulated tank to make sure it works before I risk my tank with it
Thanks
Drew
