I'm looking to make an external refugium out of a 10 gal. tank and LS and LR from my main tank. What kind of filtration(would a powerhead alone be enough)is needed and what kind of lighting.???
Just how good or bad are sand sifting stars??? I have 100 pds LS in an 85 gal. and have just purchased a sand sifting star. I always thought they were benefical but is this a myth?? Do they cause more problems than they can solve???
