So I have 46 gallon saltwater tank with some rock and it has sort of been neglected for about a year. The other day I bought a new filter and did a 95% water change. God only knows what is going on in there but the two fish that I have are alive (Damsel and maroon clown).
What measures should I take to get it back to where it should be?
