poor water quality my fish are loosing their bright colors

[natureboy1]

I am breaking down my 55 that doesnt have the greatest water quality . i do a 5 percent water change every week and have a preety good skimmer hooked up to it , but have around 10 to 15 fish i have one #6 koralia hooked up to it but have some deasd spots and too much of a bio load . I noticed one or two of my fish have been loosing their bright colors , i am upgrading everything this week to a 90 gallon drilled tank with a aqua medic metal hylide fixture with 2 150 watt 14k bulbs and a deltec 600 skimmer new rowa phas in my phos ban reactor and going to run carbon .
do you think this change will bring back their color ??
thanks for your help

IMHO, here is my $0.02

I'll suggest to test your water first to see if your water quality within acceptable range.

fish also needs time to settle in a changed enviroments so can show it's color.

food preparation is also possible to affect fish color, will suggest to buy enriched foods with vitamins, also foods such as cyclop-eeze, spectrum marine formula... all are good to bring fish to it's best color.

a healthy fish will show it's bright color, there're many factors, sick, water quality, or lack of proper nutrition.

browse around this great forum, believe you can have lots of information to get back your fish color in the right path...
