as for maintenance, i do about a 20 gallon water change any where from 4 -6 weeks and i use c-balance every day, and i use coral-vite, strom/mag and essential elements once a week on different days. and i stopped moving things around all the time.
the cleaner has been in there about 3 years, i have pretty good luck with them, he also eats spectrum food the super small size and flake food if i crumble it up.
the cap on the back wall is a beast it started the size of a silver dollar and has taken over i keep breaking off pieces and giving them to people,
thanks for the kind words about the tank, when things are going well its a lot of fun.
