I try to give up on Berlin Filter Socks, so many times, YES is pain in the neck, but I don't believe , is something better ( mechanical filter , except Protein Skimmer) to keep tank clean and healthy. CMantis is right NOT big deal for Diatom Filter, u may buy one used, or even broke, pump fall, I hate that pump, I use few times a year, if may leak, mean , u don't install the top cover correct, u have to hold w/one hand down to jar (hold some pressure) the w/anther hand start tide the screws (cross) if your sand go everywhere , may be wrong size, hard to say more Flow, when your Aqua scope may be not the best choice. If u have Nitrate , I suspect your fuge, If I was u, I will grow more chaeto Macro Algae , skip the Rowa. If you like, keep the Diatom Filter in one 5 gal. bucket when u run.
