hey
i am using a spa pool type filter. You can buy them from wetpets for 170. you cann't get anything cheaper in town too, i tried.
So if you have smaller tanks it will take a while to catch up to that.
i wish i could alan but i am just a whimp when it comes to big wigs like that. I too felt like doing more than that at the time, but oh well onward and upwards
