Need chem help!

[Tadersalid]

For the last 7 years I have set up / moved several tanks, but after about 6 months they always seam to fade the corals. I have never done any dosing just water changes every 2 weeks. I was thinking I need to start adding something to the water to help the established tank out. I was thinking about the part A and B but figured I would ask to see what would be good to dose my tank.

can we get a little more tank info please? Type of light, how old are your bulbs? And tank parameters?

 

[Wicked Color]

filtration? tank size, copper test?

Yeah, before you start putting anything in your tank you need to know what the current levels are for all the standard params: calc,alk,mag,PH,temp

Also what kinds of corals are you keeping? Obviously soft corals with have far different demands than hard corals.
