jmetzger72 6,976 Posted August 21, 2015 (edited) It is messy (just like ProGold) as it crumbles quickly. You can totally see the difference between my two double stacked tanks at feeding time. The lower tank has various sizes of fish who get a mix of NLS Thera-A and Hikari Lionhead while the upper tank has two very large fish that get the Sho Impact. The lower tank remains clean and clear, but the upper tank is a disaster for about 15 minutes Edited August 21, 2015 by Jared 0 Quote Share this post Link to post Share on other sites
