what are your Nitrate levels?
This can give an indication of whether or not you are doing enough water changes.
It also depends on how much waste is accumulating on the bottom of the tank, if there is quite a lot when you do your vacuuming, then more would be beneficial before it breaks down to produce toxins.
10g Fry / Hospital / QT tank (as needed)
75g Saltwater Reef, Ocellaris Clownfish, Lyretail Antias (baby), Lemon damsel, Longtail Fairy Wrasse, purple dottyback, snails, crabs and a few LPS corals.
220g Still sitting empty (come on Lottery I need the numbers to come up!)
