don't forget you need a good strong airpump at least 30 ltr of air per minute per bucket at least 3 6 inch airstones plenty of bubbles plenty of air tubing I think for everything for a complete set up would cost around £100 to £150 that would get you 2 buckets air pump to run both airstones and all the parts when I get a chance to order it I will do a step by step so you can watch me fuck it up :smoking:
