CORALINE IS TURNING WHITE!!! WHY????
 
THE CORALINE IN MY TANK IS TURNING FROM PURPLE TO WHITE.
IM NOT SURE WHY... RIGHT NOW IM WORKING ON DROPING THE NITRATE LEVEL. IT IS HIGH. I DONT KNOW WHY. I JUST ADDED A GOLD STIPE CLOWN TO MY TANK AND REMOVED A TOMATOE AND VELVET DAMSEL JUST 2 WEEKS AGO. ANY ADVISE TO CONTROL THIS HIGH LEVEL. I JUST DID A 5 GAL WATER CHANGE. I DONT THINK THAT HELPED THE LEVEL WAS THE SAME. IM THINKING OF DOING A 15 TO 20 GAL WATER CHANGE.. I AM ALSO GETTING A SLIGHT COAT OF BROWN ALGE ON MY GLASS.
I HAVE A PURPLE TANG A GOLDEN STRIP CLOWN, A SCOOTER BLENNY.
A CARPET AND CONDY, AND A FEATHER DUSTER. ALSO 2 CRABS AND 2 TURBO SNAILS. 55 GAL WITH CRUSHED CORAL. POWER COMPACTS 260 WATTS.
THANKS

I AM USING A API MASTER TEST KIT. THE AMMONIA NITRITE AND PH ARE IN GOOD RANGE I DONT RECALL WHAT THEY WERE BUT THE NITRATE WAS VERY HIGH. I HAVE BEEN DOING MONTHLY WATER CHANGES OF 5 GAL. AND TOP OFF DAILY. MAYBE NOT ENOUGH WATER CHANGES HUH???I DID THE WATER CHANGE THE FIRST SUNDAY THIS MONTH AND I DID IT AGAIN THIS PAST SUNDAY AFTER SEENING THE NITRATE LEVEL.
DO YOU WANT ME TO RETEST EVERYTHING ??? 55 GAL/..

Do you vacuum your CC substrate? Sometimes that can trap waste and lead to high nitrAtes. 5 gallons of water is probably not enough. I usually do about 15-20 (it may be a little less, since my bucket doesn't have any markings on it).

HELP
 
YES I TRY AND GO OVER ALL THE C-C WHEN I DO A WATER CHANGE. IT LOOKS PRETTY DIRTY WHEN I VACCUM IT. SHOULD I REMOVE MY ROCK AND VACCUM THE SUBSTRATE THOROGHLY, THEN DO A BIG WATER CHANGE??? ARE MY LIGHT GOOD ENOUGH Orbit Extreme 2x65 watt 2x65 watt DAYLIGHT AND ACITIC

You`ll need to test for Calcium and Alkalinity. This link will help to let you know where you need to be. Weekly PWC`s will help to replenish you calcium and alk levels. Also when you type in capital letters that means you are screaming or hollering. Just letting you know. Post your calcium and alk levels. I`ll bet they are low.

How often do you change your media out in your filter? Does your filter use sponges? A 20-25% PWC is a good idea for a 55g tank.

I agree with melosu58 - I'll put money on Ca at about 300-320 ppm. I know my purple started fading when my Ca hit 320ppm. Before that, I didn't realize it sucked that much up.

Once you know your Ca/Alk levels, give this one a read too...

...assuming low Ca is the problem. But I got a feeling it is. (Don't ignore the high nitrates though!)

Ack, sorry I didn't answer your question about the coraline, I got caught up in the nitrAtes. Thank guys for the assist! (even though the title asks about coraline....)
