Hey so...... I have had my BioCube up and running since June os this year, and I am having to replace the Filter cartridges ever week if not every 4 days or so, and at $5 a filter, that's costly. :wow2::wow2:Want to know from all you guys if there is an alternate filtration to put in place of the $5 a pop cartridges....... Any input would be greatly appreciated!! 


Thanks!
