Just starting out with Aqua Marine 900 set up with Marisys 240 Series 2, got 28kilo of live rock and 3-4" depth of live sand. Have 4 x 1600 circulation pumps going. Cannot seem to get rid of the micro bubbles and also totally confused by the mixed info given by different retailers. Already have carbon in the Marisys (came with), advised to remove the ceramic sub. Been told now to add phosphate by one retailer but told not to by another. Can anyone advise me which way is right. All advise gratefully received. Got to this point and now totally confused about how to move forwards. Although really enjoying rock watching and amazed to find that already have feather dusters appearing in abundance on one of the smaller rocks. Worried about doing the wrong thing and losing them! Can anyone help and talk me through the next stages?
