Hello all, When i first started this tank my goal was to go skimmer-less ala David Grigor and rely more on the ATS and refugium for nutrient export. So far my ATS (an L2 from Turbo) runs decently and i have been getting okay harvests. It is hard to see how well it is doing since my tank is still very young. I am also running a GFO/Carbon dual reactor. I have been running a HOB Remora Skimmer for when i add new livestock and a couple of times over the weekend. The pull has varied, with some times getting a nice dark skimmate, and other times nothing productive at all. Here is my question: I think my current ATS is not big enough to handle a skimmer-less filtration. I am trying to decide if i want to get another ATS or if i should give in and just get a skimmer. First off, i liked the idea of ATS- the notion of using algae as a filtration/nutrient export just appeals to me. Second, i was very wary of malfunctioning skimmers, with skimmate cups overflowing, or noise, or other issues. I am again left with the question of whether or not i should try and still go skimmer-less (and get another ATS) or are skimmers worth it? I know they seem ubiquitous but i am not sure why. To give context, my tank is mostly going with soft coral, with some LPS and maybe just maybe in the far future a piece or two of SPS which seems to be the ones that require nutrient-clear water. My understanding is that softies like having a bit more in terms of nutrients in the water. I know this is not a black or white answer, but i wanted to see if i was missing something to consider.
