So you set this tank up last month and you already have:
1 volitan lion fish
1 yellow eye tang
1 dragon goby
1 tomato clown
1 yellow tail damsel
1 picasso triggerfish
#1 You have added too many fish in too short a period of time. You should be adding fish at a rate of 1 - 2 per month.
#2 Maintaining a SW
tank requires that you have water test kits on hand to test your water weekly at a minimum for at least the first year. Get good quality liquid/powder based kits (I use Salifert for most).
Telling us that a water parameter is high is meaningless. You must know and post actual numbers. Ammonia and Nitrite even in small quantities are toxic to fish.
So let's start with the newbie questions:
What size is your tank? 55 gallon
How old is your tank ? 6 weeks?
How did you cycle your tank and when?
What has changed in your tank (new livestock, additives, partial water change, etc.)
How much LR
, a/o LS
is in the tank?
Was the LR
cured ? (when)
What inhabitants do you have ? listed above or in your 'tank" profile
What filter(s) are you running ?
What Power Heads are you running?
How are you making you salt water for PWCs?
What kind of H20 are you using ? Distilled , tap , RO
How often and how large are your partial water changes?
Are you using any additives?
What are your water parameters ?
(Specific Gravity / Salinity)
Measured with a refactometer or hydrometer (swing arm?)
