Putting my 12 gallon fuge online and I have it setup with a spraybar fed from my return pump manifold. It's getting low turnover of maybe 50gph. My chaeto doesn't seem to really be getting enough flow to "aggitate" or tumble and I'm looking to add a small ph. Would you guys think a Koralia nano to be enough or should I step up to a Koralia 1? I also have MJ 600, 900, and 1200's sitting around but not a huge fan of the direct flow produced by the MJ's in a fuge.
