Hi to all,
As it says in the title, I would like to know how often I can do a water change. The tank is new, and a little high in nitrates, and the water changes will only really be to get this down to a manageable level so I can start thinking about more inverts and corals.
It is a Fluval Edge 46l, with no sump, or skimmer, so unless someone knows of an easy way to reduce nitrates in a tank like this, water changes seem to be the only option.
I've got enough live rock, 2 small clowns, a hermit crab and a snail.
Thanks in advance.
