Yea, No refugium and it needs it a few times a week. I only do the front of my tank. I don't use a magfloat. I have one but it sometimes gets a grain of sand in it and it will scratch the acrylic. So now I have the Kent pole and soft mop head thing. Which works great if I use it every day. I usually use a hand mit. That works great in my seamless bends in the acrylic. The plaztic scraper head for the kent pole works awsome as well. Just some of my thoughts on acrylic cleaning products.
