I have had my Remora Pro HOB now for about 8months and in the last month have purchased the overflow box for it. Before using the overflow box, I would get a decent amount of wet skimmate in the collection box. But since putting on the overflow i get minimal skimmate. I have the collection box pushed down as far as possible so i can still grab it out. I get some noticeable foam at the top of the tube yet no mass quantities. Also since putting in the overflow, my surface water is much cleaner without any of the brown slimecoating like it used to have. My question is am I doing everything write or is my tank just cleaner. I did lose two fish and now only have a sailfin tang, coral beauty, sixline, flamehawk, and three small yellow damsels. Also i have the Rio1400 on it. And the only filtration is LR and skimmer. any advice would be wonderful
